Microsoft-owned GitHub has finally moved its snapshot of all active public repositories on the site to a vault in Norway. ZDNet reports: GiHub announced the archiving plan last November and on February 20 followed through with the 21 terabyte snapshot written to 186 reels of film. GitHub cancelled plans for a team to "personally escort the world's open-source code to the Arctic" due to the coronavirus pandemic, leaving the job to local partners who received the boxed films and deposited them in an old coal mine on July 8. The archive is being stored in Svalbard, Norway, a group of islands that's also home to the global seed bank.

"The code landed in Longyearbyen, a town of a few thousand people on Svalbard, where our boxes were met by a local logistics company and taken into intermediate secure storage overnight," said Julia Metcalf, director of strategic programs at GitHub. "The next morning, it traveled to the decommissioned coal mine set in the mountain, and then to a chamber deep inside hundreds of meters of permafrost, where the code now resides fulfilling their mission of preserving the world's open-source code for over 1,000 years." The repository includes public code repositories and significant dormant repos. The snapshot consists of the HEAD of the default branch of each repository, minus any binaries larger than 100kB in size. Each repository is then packaged as a single TAR file, and for efficiency's sake, most of the data will be stored as QR codes. A human-readable index and guide will itemize the location of each repository and explain how to recover the data.

A Wall Street Journal investigation found that Google gives its online video service YouTube the advantage when choosing the best video clips to promote from around the web. From the report: Take a clip of basketball star Zion Williamson that the National Basketball Association posted online in January, when he made his highly anticipated pro debut. The clip was popular on Facebook Inc., drawing more than one million views and nearly 900 comments as of March. A nearly identical YouTube version of the clip with the same title was seen about 182,000 times and garnered fewer than 400 comments. But when The Wall Street Journal's automated bots searched Google for the clip's title, the YouTube version featured much more prominently than the Facebook version.

The Journal conducted Google searches for a selection of other videos and channels that are available on YouTube as well as on competitors' platforms. The YouTube versions were significantly more prominent in the results in the vast majority of cases. This isn't by accident. Engineers at Google have made changes that effectively preference YouTube over other video sources, according to people familiar with the matter. Google executives in recent years made decisions to prioritize YouTube on the first page of search results, in part to drive traffic to YouTube rather than to competitors, and also to give YouTube more leverage in business deals with content providers seeking traffic for their videos, one of those people said. A Google spokeswoman, Lara Levin, said there is no preference given to YouTube or any other video provider in Google search. "Our systems use a number of signals from the web to understand what results people find most relevant and helpful for a given query," Ms. Levin said. She declined to comment on the specific examples cited in the article.

An anonymous reader quotes a report from The Drive: With select bucket seats from the 911 and 718 as well as various classic car parts -- including clutch release levers for the 959 -- already being produced using 3D printing, Porsche is more familiar with the technology than most. Now, the automaker is taking things even further, 3D printing entire pistons for its most powerful 991-gen 911, the GT2 RS. Although it doesn't sound like these 3D-printed pistons will actually be found in many production Porsches anytime soon, they represent a bit more than just an engineering flex. There are some very real mechanical benefits here. For starters, they weigh 10 percent less than their forged equivalents and feature an integrated and closed cooling duct in the piston crown that's apparently unable to be reproduced using traditional manufacturing methods. The decrease in weight and temperature results in an extra 30 horsepower on top of the GT2 RS's already mighty 700.

Produced in partnership with German auto part maker Mahle and industrial machine manufacturer Trumpf, the pistons are made out of a high-purity metal powder developed in-house by the former using the laser metal fusion process, essentially a laser beam that heats and melts the metal powder into the desired shape. The end result is then validated using measurement technology from Zeiss, the German optics company best known for camera lenses.

"One of the main reasons we're not all driving electric vehicles is the price," argues a transportation writer in Forbes — explaining how Tesla hopes to finally change that: The company is placing a huge bet on rechargeable battery technology that doesn't use cobalt. This is one of the main elements making lithium ion batteries so expensive. It's also fraught with political issues, since the mining can be in conflict areas like the Congo, and its production is considered quite polluting of the environment. But cobalt is used because it enables the energy density required in batteries intended to last for hundreds of miles per charge. A couple of months ago, it was revealed that Tesla was working with CATL on lithium iron phosphate (LFP) batteries, and these could be the real gamechanger. LFP batteries don't use cobalt and have a roadmap to push well past the magical $100 per kWh (wholesale) that is considered the threshold for EVs being cheaper than Internal Combustion Engine (ICE) vehicles...

Tesla has also recently patented technology for cathodes that significantly improves the number of charge cycles... The new Tesla technology, patented by the company's battery team led by Jeff Dahn, can increase charge cycles to nearly 4,000, which would be more like 75 years if charged once a week — hence the talk of million-mile batteries. More recently, the Tesla team headed by Jeff Dahn patented some new technology for lithium metal/anode free batteries, which could drastically improve energy density and thereby considerably reduce costs. These technologies, if they become commercially viable, could revolutionize battery durability and price, and there's another technology called all-polymer batteries on the horizon that is being developed by a former Nissan senior researcher, which he claims could cut 90% off the current price.

But these are improvements for the future that may not happen, and cobalt-free lithium iron phosphate batteries are here now. Tesla will be using LFP for the batteries in its Chinese Model 3, after receiving government approval to do so. It is estimated that using LFP batteries will allow a 15-20% reduction in manufacturing cost. Taking calculations regarding how much of a car's cost is batteries into account, this could make EVs a mere 10% more expensive than ICE instead of 30%, which will be easy to regain in cheaper running costs over a year or two of ownership. It will also give EVs an even greater lead over fuel-cell technology, making it even less likely that hydrogen will be the future of electric cars.

The time is fast approaching when EVs are not just more ecological and cheaper to run than ICE cars, but cheaper to buy too, and batteries free of cobalt are a key step in that direction. That's why Tesla's shift to LFP is so significant — it could be the final nail in the coffin for fossil fuel vehicles.

Research continues in a field which involves using the spin and magnetism of electrons in solid-state devices — spintronics.

hackingbear shared this report from Nature: Electric control of magnetic vortex dynamics in a reproducible way on an ultrafast time scale is a key element in the quest for efficient spintronic devices with low-energy consumption. Researchers in China and Germany demonstrated a simple method for controlling magnetic patterns that are useful for data storage and information processing.

Magnetic nanostructures are engineered as to host swirling magnetic vortices. The vortex intrinsic properties such as the vortex sense of rotations or polarity are well defined and thus are predestinate as digital information carriers. Furthermore, the magnetic nanostructures are readily integrated in existing computers. Chenglong Jia from Lanzhou University, Jamal Berakdar from Martin-Luther Universitat Halle-Wittenberg and their co-workers demonstrated how to process the so stored information swiftly by switching both the vortex's sense of rotation and the orientation of its magnetic field using at a simple sequence of ultra-short, low average-energy electric-field pulses. The team believe that their method is scalable, non-invasive, reliable and reversible, fullfing thus important prerequisites for practical implementation.

A new Motherboard article interviews William, a ventilator refurbisher who's repaired at least 70 broken ventilators that he's bought on eBay and from other secondhand websites, then sold to U.S. hospitals and governments to help handle a spike in COVID-19 patients.

He's part of a grey-market supply chain that's "essentially identical to one used by farmers to repair John Deere tractors without the company's authorization and has emerged because of the same need to fix a device without a manufacturer's permission..." The issue is that, like so many other electronics, medical equipment, including ventilators, increasingly has software that prevents "unauthorized" people from repairing or refurbishing broken devices, and Medtronic will not help him fix them... Faced with a global pandemic, hospitals, biomedical technicians, right to repair activists, and refurbishers like William say that medical device manufacturers are profiteering by putting up artificial barriers to repair that drive up the cost of medical care in the United States and puts patient lives in danger. They describe difficulty getting parts and software, delays in getting service from "authorized" technicians, and a general sense of frustration as few manufacturers appear ready to loosen their repair restrictions during the COVID-19 crisis.

For the past decade, medical device manufacturers have refused to sell replacement parts and software to hospitals and repair professionals unless they pay thousands of dollars annually to become "authorized" to work on machines. The medical device industry has lobbied against legislation that would make it easier to repair their machines, refused to release repair manuals, and used copyright law to threaten those who have made repair manuals available to the public. The technicians who are unable to gain access to repair parts, manuals, and software are not random people who are deciding on a whim to try to fix complex medical equipment that is going to be used on sick patients. Hospitals and trained professionals are regularly unable to fix the equipment that they own unless they pay for expensive service contracts or annual trainings from manufacturers.

While hospitals deal with a resurgent coronavirus that is overtaxing intensive care units across the country, their biomedical technicians are wasting time on the phone and in Kafkaesque email exchanges with medical device manufacturers, pleading for spare parts, passwords to unlock diagnostic modes, or ventilator repair manuals.
The article notes that newer medical devices even have "more advanced anti-repair technologies built into them. Newer ventilators connect to proprietary servers owned by manufacturers to verify that the person accessing it is authorized by the company to do so."

At Tyson's 26,000-square-foot, multi-million dollar Manufacturing Automation Center near its headquarters in Springdale, Arkansas, the company will apply the latest advances in machine learning to meat manufacturing, with the goal of eventually eliminating jobs that can be physically demanding, highly repetitive and at times dangerous. Bloomberg reports: Advances in technology are making it possible to make strides in automation. For example, machine vision is now accurate and speedy enough to apply to meat production, which is highly labor intensive compared with other food manufacturing. Also, a lot of washing and sanitizing occurs in a meat-packing plant, which has traditionally been difficult on robots, but now the machines are built to withstand that. At Tyson's new facility, a series of laboratories showcase different types of robots. Mechanical arms in glass cases use smart cameras to sort colorful objects or stack items. In another room, a larger machine called a palletizer performs stacking tasks. There's also a training space.

Many of the types of robots that a meatpacking plant would need are not on the market currently, so the company needs to innovate and collaborate with partners to create them, said Doug Foreman, a director in engineering at Tyson. But the technology is ready. The processing capabilities of cameras are "so advanced even from a few years ago," Foreman said. "Processing-speed-wise, it's there now for us."

An anonymous reader quotes a report from Engadget: The PC industry bounced back in the second quarter of 2020 after its weakest quarter in years mostly due to shelter-in-place orders prompted by the coronavirus pandemic. According to both Gartner and IDC, PC shipments grew year-over-year in the second quarter -- the former says shipments totaled 64.8 million units (a 2.8 percent increase from Q2 2019), while IDC says global shipments reached 72.3 million units, which is 11.2 percent higher compared to the same period last year.

Both organizations attribute the growth to PC production ramping up after supply chains were disrupted in the first quarter and to strong demand, now that more people need computers to work or study from home. "After the PC supply chain was severely disrupted in early 2020 due to the COVID-19 pandemic, some of the growth this quarter was due to distributors and retail channels restocking their supplies back to near-normal levels," Gartner research director Mikako Kitagawa said. The mobile PC or laptop segment did very well, in particular, due to people's remote learning and working needs. However, both organizations are skeptical that the demand would continue beyond 2020. Gartner and IDC also noted that traditional PC shipments exceeded expectations in the U.S. and in the Europe, Middle East and Africa (EMEA) region. "HP and Lenovo topped the list of PC vendors worldwide, with Dell coming in third for both IDC and Gartner," adds Engadget.

An anonymous reader quotes a report from Bloomberg: Lithium-ion batteries play a central role in the world of technology, powering everything from smartphones to smart cars, and one of the people who helped commercialize them says he has a way to cut mass production costs by 90% and significantly improve their safety. Hideaki Horie, formerly of Nissan Motor Co., founded Tokyo-based APB Corp. in 2018 to make "all-polymer batteries" -- hence the company name. The making of a cell, every battery's basic unit, is a complicated process requiring cleanroom conditions -- with airlocks to control moisture, constant air filtering and exacting precision to prevent contamination of highly reactive materials. The setup can be so expensive that a handful of top players like South Korea's LG Chem Ltd., China's CATL and Japan's Panasonic Corp. spend billions of dollars to build a suitable factory.

Horie's innovation is to replace the battery's basic components -- metal-lined electrodes and liquid electrolytes -- with a resin construction. He says this approach dramatically simplifies and speeds up manufacturing, making it as easy as "buttering toast." It allows for 10-meter-long battery sheets that can be stacked on top of each other "like seat cushions" to increase capacity, he said. Importantly, the resin-based batteries are also resistant to catching fire when punctured. In March, APB raised $74 million, which is tiny by the wider industry's standards but will be enough to fully equip one factory for mass production slated to start next year. Horie estimates the funds will get his plant in central Japan to 1 gigawatt-hour capacity by 2023.

tlhIngan writes: For those worried that the transition Apple is doing to ARM-based Macs will drop Thunderbolt, Apple has stated that they will continue to support Thunderbolt. This was a worry since Thunderbolt is primarily an Intel design (formerly known as Light Peak) with Apple collaboration, and that none of Apple's ARM based devices support it (not even the ARM Developer Transition Kit).

Today, Qualcomm is announcing an update to its extremely successful Snapdragon 865 SoC: the new Snapdragon 865+. AnandTech reports: The new Snapdragon 865+ is a new binned variant of the [Snapdragon 865] with higher peak frequencies on the part of the "prime" CPU as well as the GPU, promising +10% performance on both aspects. Whilst in relative terms the new chipset's +10% clock improvement isn't all that earth-shattering, in absolute terms it finally allows the new Snapdragon 865+ to be the first mobile SoC to break past the 3GHz threshold, slightly exceeding that mark at a peak 3.1GHz frequency. Ever since the Cortex-A75 generation we've seen Arm make claims about their CPU microarchitectures achieving such high clock frequencies -- however in all those years actual silicon products by vendors never really managed to quite get that close in commercial mass-production designs.

We've had a chat with Qualcomm's SVP and GM of mobile business Alex Katouzian, about how Qualcomm achieved this, and fundamentally it's a combination of aggressive physical design of the product as well as improving manufacturing yields during the product's lifecycle. Katouzian explained that they would have been able to achieve these frequencies on the vanilla Snapdragon 865 -- but they would have had a lower quantity of products being able to meet this mark due to manufacturing variations. Yield improvements during the lifecycle of the Snapdragon 865 means that the company is able to offer this higher frequency variant now. [...] There will be a power increase to reach the higher frequencies, however this will only be linear with the increased clock speed, meaning energy efficiency of the new SoC will maintain the same excellent levels of that of the Snapdragon 865, so battery life will not be affected. [...] Amongst other new novelties of the Snapdragon 865+ platform is the ability for vendors to bundle with the new FastConnect 6900 Wi-Fi chips from Qualcomm, the company's new Wi-Fi 6 chipsets with 6GHz band capability (Wi-Fi 6E).

Zoom is teaming up with four video conferencing hardware makers to launch Zoom Hardware as a Service, designed to make Zoom Rooms and Zoom Phone more available to enterprises. ZDNet reports: The hardware providers in the package are DTEN, Neat, Poly, and Yealink. The hardware and Zoom bundles give tech buyers a monthly fixed price that varies by system and support by Zoom. Neat and DTEN have already designed hardware systems revolving around Zoom, which has become a household name with growth to match following the remote work shift during the COVID-19 pandemic. Zoom's Hardware as a Service (HaaS) pricing varies depending on hardware. For instance, Zoom Phone hardware runs from $5.99 per device for the Poly VVX 250 to $50 a month for the Yealink CP960. Zoom Hardware as a Service doesn't include software license costs.

The Zoom Rooms Hardware as a Service plans are pricier than Zoom Phone options. Pricing for Zoom Rooms hardware range from the Neat.bar with Neat.Pad controller at $110 a month per device to Poly systems that range from $100 a month to $150 a month. Software licensing costs aren't included. Zoom HaaS like other as-a-service efforts provides low upfront costs and predictable budgeting as well as the ability to scale up or down and get managed support.

MojoKid writes: Last month, AMD made its Ryzen 3000XT series processors official, after weeks of leaks and speculation. Ryzen 3000XT series processors are tweaked versions of the original 3000X series products, but with higher clocks and the ability to maintain turbo frequencies longer. Launching today, AMD's new Ryzen 5 3600XT is a 6 core/12-thread processor, with a 3.8GHz base clock and a 4.5GHz max boost clock. That's a 100MHz increase over the 3600X. The Ryzen 7 3800XT is an 8-core/16-thread processor with a base clock of 3.9GHz and a max boost clock of 4.7GHz, which is 200MHz higher than the original 3800X. Finally, the Ryzen 9 3900XT is a 12-core/24-thread processor with a base clock of 3.8GHz with a max boost clock of 4.7GHz, which is a 100MHz increase over the original Ryzen 9 3900X.

AMD also notes these new processors can maintain boost frequencies for somewhat longer durations as well, which should offer an additional performance uplift, based on refinements made to the chip's 7nm manufacturing process. In testing, the new CPUs offer small performance gains over their "non-XT" namesakes, with 100MHz - 200MHz increases in boost clocks resulting in roughly 2% - 5% increases to both their single and multi-threaded performance in most workloads. Those frequency increases come at the expense of slightly higher peak power consumption as well of course. The best news may be that AMD's original Ryzen 5 3600X, Ryzen 7 3800X, and the Ryzen 9 3900X will remain in the line-up for the time being, but their prices will be slashed a bit, with the new Ryzen 5 3600XT, Ryzen 7 3800XT, and Ryzen 9 3900XT arriving with the same $249, $399, and $499 introductory prices as the originals.

Nokia has become the first major telecom equipment maker to commit to adding open interfaces in its products that will allow mobile operators to build networks that are not tied to a vendor. Reuters reports: The new technology, dubbed Open Radio Access Network (Open RAN), aims to reduce reliance on any one vendor by making every part of a telecom network interoperable and allowing operators to choose different suppliers for different components. Currently, Nokia along with Ericsson and Huawei supplies most of the equipment for building telecom networks and mobile operators can only pick one for each part of their network.

As part of the implementation plan, Nokia plans to deploy Open RAN interfaces in its baseband and radio units, a spokesman said. An initial set of Open RAN functionalities will become available this year, while the full suite of interfaces is expected to be available in 2021, the company said. Nokia, unlike other vendors, had been promising to participate in the development of open RAN technology and have joined several industry alliances.

An anonymous reader quotes a report from The Guardian: A giant flywheel in north-east Scotland could soon help to prevent blackouts across Britain by mimicking the effect of a power station but without using fossil fuels. The trailblazing project near Keith in Moray, thought to cost about 25 million British pounds, will not generate electricity or produce carbon emissions -- but it could help keep the lights on by stabilizing the energy grid's electrical frequency. The Norwegian energy company Statkraft hopes that from next winter the new flywheel, designed by a division of General Electric, will be able to mimic the spinning turbines of a traditional power station, which have helped to balance the grid's frequency at about 50 hertz for decades.

Currently, the National Grid Electricity System Operator (ESO) is forced to shut down windfarms and run gas power stations even when there is more than enough renewable energy to meet Britain's electricity demand, in order to keep the grid's frequency steady. By simulating the spinning metal mass of a power station turbine without producing emissions, Statkraft should be able to help ESO rely less on fossil fuels and use renewable energy more. This is the first time a project of this kind will be used anywhere in the world and ESO believes it could be a "huge step forward" in running a zero-carbon electricity grid.

According to Nikkei Asian Review, much of the PlayStation's success can be attributed to an unassuming factory in Japan that is almost entirely operated by robots. From the report: On the outskirts of Kisarazu, a large, white building towers over an otherwise suburban landscape. Once inside, visitors are greeted by the whirring of motors as dozens of robots seamlessly churn out PlayStation 4 consoles. Just a few humans were present to deal with a handful of tasks -- two to feed bare motherboards to the line, and two to package the finished consoles. But the actual assembly is done entirely by articulated robots, supplied by Mitsubishi Electric. The 31.4-meter line, completed in 2018, has the ability to churn out a new console every 30 seconds.

The Kisarazu plant is operated by Sony Global Manufacturing & Operations, or SGMO, the group's manufacturing arm. The unit has worked with video game unit Sony Interactive Entertainment to bring cutting-edge technologies to the facility. One of the plant's crowning achievements is the use of robots to attach wires, tape and other flexible parts to the consoles. Twenty-six out of 32 robots at the Kisarazu plant are dedicated to the task, deftly handling materials most robots would find too finicky. "There's probably no other site that can manipulate robots in this manner," said an engineer. Every process -- all the way to final packaging -- is automated. The blend of robotic and human labor is painstakingly optimized with a priority on return on investment.

German lawmakers have finalized the country's long-awaited phase-out of coal as an energy source, backing a plan that environmental groups say isn't ambitious enough and free marketeers criticize as a waste of taxpayers' money. From a report: Bills approved by both houses of parliament Friday envision shutting down the last coal-fired power plant by 2038 and spending some $45 billion to help affected regions cope with the transition. The plan is part of Germany's 'energy transition' -- an effort to wean Europe's biggest economy off planet-warming fossil fuels and generate all of the country's considerable energy needs from renewable sources. Achieving that goal is made harder than in comparable countries such as France and Britain because of Germany's existing commitment to also phase out nuclear power by the end of 2022. "The days of coal are numbered in Germany," Environment Minister Svenja Schulze said. "Germany is the first industrialized country that leaves behind both nuclear energy and coal." Greenpeace and other environmental groups have staged vocal protests against the plan, including by dropping a banner down the front of the Reichstag building Friday. They argue that the government's road map won't reduce Germany's greenhouse gas emissions fast enough to meet the targets set out in the Paris climate accord.

An anonymous reader quotes a report from Wired: A new generation of reactors coming online in the next few years aims to make nuclear meltdowns a thing of the past. Not only will these reactors be smaller and more efficient than current nuclear power plants, but their designers claim they'll be virtually meltdown-proof. Their secret? Millions of submillimeter-size grains of uranium individually wrapped in protective shells. It's called triso fuel, and it's like a radioactive gobstopper. Triso -- short for "tristructural isotropic" -- fuel is made from a mixture of low enriched uranium and oxygen, and it is surrounded by three alternating layers of graphite and a ceramic called silicon carbide. Each particle is smaller than a poppy seed, but its layered shell can protect the uranium inside from melting under even the most extreme conditions that could occur in a reactor.

Paul Demkowicz is the director of the Advanced Gas Reactor Field Development and Qualification Program at Idaho National Laboratory, and a large part of his job is simulating worst-case scenarios for next-generation nuclear reactors. For the past few years, Demkowicz and his colleagues have been running qualification tests on triso fuel that involve putting them in a reactor and cranking the temperature. Most nuclear reactors today operate well below 1,000 degrees Fahrenheit, and even the next generation high-temperature reactors will top out at about 2,000 degrees. But during the INL tests, Demkowicz demonstrated that triso could withstand reactor temperatures over 3,200 degrees Fahrenheit. Out of 300,000 particles, not a single triso coating failed during the two-week long test. "In the new reactor designs, it's basically impossible to exceed these temperatures, because the reactor kind of shuts down as it reaches these high temperatures," says Demkowicz. "So if you take these reactor designs and combine them with a fuel that can handle the heat, you essentially have an accident-proof reactor."

One of the two leading manufacturers of tape cartridge storage, FujiFilm, claims that they have a technology roadmap through to 2030 which builds on the current magnetic tape paradigm to enable 400 TB per tape. AnandTech reports: As reported by Chris Mellor of Blocks and Files, Fujifilm points to using Strontium Ferrite grains in order to enable an areal data density on tape of 224 Gbit-per-square-inch, which would enable 400 TB drives. IBM and Sony have already demonstrated 201 Gbit-per-square-inch technology in 2017, with a potential release of the technology for high volume production in 2026. Current drives are over an order of magnitude smaller, at 8 Gbit-per-square-inch, however the delay between research and mass production is quite significant.

Strontium Ferrite would replace Barium Ferrite in current LTO cartridges. Strontium sits on a row above Barium in the periodic table, indicating a much smaller atom. This enables for much smaller particles to be placed into tracks, and thankfully according to Fujifilm, Strontium Ferrite exhibits properties along the same lines as Barium Ferrite, but moreso, enabling higher performance while simultaneously increasing particle density. [...] Fujifilm states that 400 TB is the limit of Strontium Ferrite, indicating that new materials would be needed to go beyond. That said, we are talking about only 224 Gbit-per-square-inch for storage, which compared to mechanical hard disks going beyhind 1000 Gbit-per-square-inch today, there would appear to be plenty of room at the top if the technologies could converge.

An anonymous reader quotes a report from Ars Technica: After years of repackaging the same basic smartwatch chip over and over again, Qualcomm has graced Wear OS with a modern smartwatch SoC. Meet the Snapdragon Wear 4100, a Qualcomm smartwatch chip that, for the first time ever, is faster than the previous chip. The Wear 4100 uses four 1.7GHz Cortex A53 CPUs built on a 12nm manufacturing process, a major upgrade from the 28nm Cortex A7s that every other Qualcomm smartwatch chip has been up until now. It's not the state-of-the-art 7nm process that Qualcomm's high-end chip uses, and the Cortex A53 is an old CPU design, but for Qualcomm, it's a major upgrade. Between the new CPU, the Adreno 504 GPU, and faster memory, Qualcomm is promising "85% faster performance" compared to the Wear 3100.

There are actually two versions of the 4100, the vanilla "4100" and the "4100+." The plus version is specifically for smartwatches with an always-on watch face, and like previous Wear SoCs, comes with an extra low-power SoC (based around a Cortex-M0) to keep the time updated and log sensor data (like step counts). Qualcomm is promising a better display image quality in this low-power mode, with more colors and a smoother display. There are also dual DSPs now, which Qualcomm says are for "optimal workload partitioning, support for dynamic clock and voltage scaling, Qualcomm Sensor Assisted Positioning PDR Wearables 2.0, low power location tracking support, and an enhanced Bluetooth 5.0 architecture." There are also dual ISPs with support for 16MP sensors (on a smartwatch?). As usual, connectivity options are plentiful, with onboard LTE, GPS, NFC, Wi-Fi 802.11n, and Bluetooth 5.
