World's Largest Chip Maker Will Lose $250M For Not Patching Windows 7 Computers (networkworld.com) 108

A major virus infection forced the closure of Taiwan Semiconductor Manufacturing Company (TSMC) factories last weekend..." writes Slashdot reader Mark Wilson, noting that it's the largest semiconductor manufacturer in the world, selling chips to Apple, Nvidia, AMD, Qualcomm, and Broadcom, and "responsible for producing iPhone processors."

Now Network World reports: The infection struck on Friday, August 3, and affected a number of unpatched Windows 7 computer systems and fab tools over two days. TSMC said it was all back to normal by Monday, August 6. TSMC did not say it was WannaCry, aka WannaCrypt, in its updates, but reportedly blamed WannaCry in follow-up conference calls with the press.... The company said this incident would cause shipment delays and additional costs estimated at 3 percent of third quarter revenue. The company had previously forecast revenues of $8.45 billion to $8.55 billion for its September quarter. A 3 percent loss would mean $250 million, though actual losses may come out lower than that. Still, that's a painful hit. TSMC also said no customer data was compromised....

TSMC isn't directly to blame here; someone [an infected production tool provided by an unidentified vendor] brought WannaCry into their offices and behind their firewall, but TSMC is still culpable because it left systems unpatched more than a year after WannaCry hit.

AMD Creates Quad Core Zen SoC with 24 Vega CUs for Chinese Consoles (anandtech.com) 93

An anonymous reader shares a report: AMD has cornered the x86 console market with its handy semi-custom mix of processors and graphics. While we slowly await the next generation of consoles from Microsoft and Sony, today AMD and Zhongshan Subor announced that a custom chip has been made for a new gaming PC and an upcoming console for the Chinese market.

The announcement states that a custom chip has been created for Subor that is based on four Zen cores running at 3.0 GHz and 24 compute units of Vega running at 1.3 GHz. The chip is supported by 8GB of GDDR5 memory, which the press release states is also embedded onto the chip, however it is likely to actually be on the package instead. [...] Assuming that this custom chip is a single chip design, with CPU and GPU, this means that AMD is handily gaining custom contracts and designing custom chip designs for its customers, even for consoles that won't have the mass western appeal such as the Xbox or Playstation.

Researchers Detail New CPU Side-Channel Attack Named SpectreRSB (bleepingcomputer.com) 39

An anonymous reader writes: "Scientists from the University of California, Riverside (UCR) have published details last week about a new Spectre-class attack that they call SpectreRSB," reports Bleeping Computer. "Just like all 'Spectre-class' attacks, SpectreRSB takes advantage of the process of speculative execution -- a feature found in all modern CPUs that has the role of improving performance by computing operations in advance and later discarding unneeded data. The difference from previous Spectre-like attacks is that SpectreRSB recovers data from the speculative execution process by attacking a different CPU component involved in this 'speculation' routine, namely the Return Stack Buffer (RSB)." In a research paper, academics say they've used SpectreRSB attacks to recover data belonging to other processes, and have even tricked the RSB into spilling SGX secrets. The attack works on Intel, AMD, and ARM processors, known to use RSB. The attack can also bypass all the mitigations put in place for the original Spectre/Meltdown flaws.

Apple Partnered With Blackmagic On An External GPU For MacBooks (techcrunch.com) 102

Apple has worked with cinema company Blackmagic on an external GPU based around an AMD Radeon Pro 580 graphics card with 8GB of DDR5 RAM. The Blackmagic eGPU features "an HDMI port, four USB 3.1s and three Thunderbolt 3s, the latter of which makes it unique among these peripherals," reports TechCrunch. From the report: The company says the on-board cooling system operates pretty quietly, which should fit nicely alongside those new, quieter MacBook keyboards. Many developers will no doubt prefer to configure their own, but for those who want an easier solution for playing resource-intensive games or graphics rendering on with a MacBook, this is a fairly simple solution. The [$699] eGPU is available now through Apple's retail channels.

Apple Refreshes MacBook Pro Lineup (arstechnica.com) 217

Apple said on Thursday it is refreshing the 13-inch and 15-inch MacBook Pro models. Neither machines are getting major redesigns, but the innards are getting a spec update. For starters, both the models are powered by the 8th-generation Intel processors and house more cores than before -- a maximum of six cores on the 15-inch model (compared to four in last year's models) and four in the 13-inch model (compared to two). That means faster performance for many use cases. Maximum SSD capacity is also doubled, and the MacBook Pro line offers DDR4 RAM for the first time. ArsTechnica: The laptops also borrow some features from the iMac Pro and the iPad Pro -- the T2 chip and True Tone, respectively -- and feature a revised butterfly keyboard, the third generation of the design Apple introduced in 2016 (the revision is a little more significant this time around). Apart from those tweaks to the keyboard, the basic design of the MacBook Pro is unchanged. The top configuration of the 15-inch model includes an 8th-generation, six-core Intel Core i9 CPU clocked at 2.9GHz. Six-core Intel Core i7 processors are also options. The 2017 iteration of the MacBook Pro featured DDR3 memory with a maximum configuration of 16GB. This time, it's DDR4, and the maximum is 32. The faster memory uses more energy, so a bigger battery is now included -- but Apple's battery life estimate remains the same as last year's. The GPU in the top standard configuration is listed as an AMD Radeon Pro 555X.

The 13-inch model has different specs, of course. It still only offers integrated Intel graphics, for one thing -- Intel Iris Plus 655, this time with 128MB of eDRAM. But the maximum number of cores are again doubled -- in this case to four -- in 8th-generation Intel Core i5 or Core i7 CPUs, which run at up to 2.7GHz. Maximum SSD capacity is also doubled; it's now 2TB. The maximum memory is still 16GB. Apple claims the 13-inch model is up to twice as fast as its predecessor, though it will of course depend on the application.
ArsTechnica says the keyboard on the new MacBook Pro models, though look similar to the one in the predecessor lineup, feel a little different to type on. The price of 13-inch starts at $1,799 while the 15-inch starts at $2,399.

AV1 is Well On Its Way To Becoming a Viable Alternative To Patented Video Codecs, Mozilla Says (mozilla.org) 66

Here's a surprising fact: It costs money to watch video online, even on free sites like YouTube. That's because about 4 in 5 videos on the web today rely on a patented technology called the H.264 video codec. From a report: It took years for companies to put this complex, global set of legal and business agreements in place, so H.264 web video works everywhere. Now, as the industry shifts to using more efficient video codecs, those businesses are picking and choosing which next-generation technologies they will support. The fragmentation in the market is raising concerns about whether our favorite web past-time, watching videos, will continue to be accessible and affordable to all.

Over the last decade, several companies started building viable alternatives to patented video codecs. Mozilla worked on the Daala Project, Google released VP9, and Cisco created Thor for low-complexity videoconferencing. All these efforts had the same goal: to create a next-generation video compression technology that would make sharing high-quality video over the internet faster, more reliable, and less expensive. In 2015, Mozilla, Google, Cisco, and others joined with Amazon and Netflix and hardware vendors AMD, ARM, Intel, and NVIDIA to form AOMedia. As AOMedia grew, efforts to create an open video format coalesced around a new codec: AV1. AV1 is based largely on Google's VP9 code and incorporates tools and technologies from Daala, Thor, and VP10.

Mozilla loves AV1 for two reasons: AV1 is royalty-free, so anyone can use it free of charge. Software companies can use it to build video streaming into their applications. Web developers can build their own video players for their sites. The second reason we love AV1 is that it delivers better compression technology than even high-efficiency codecs -- about 30% better, according to a Moscow State University study.

China Begins Production Of x86 Processors Based On AMD's IP (tomshardware.com) 189

Chinese-designed "Dhyana" x86 processors based on AMD's Zen microarchitecture are beginning to surface from Chinese chip producer Hygon. From a report: The processors come as the fruit of AMD's x86 IP licensing agreements with its China-based partners and break the decades-long stranglehold on x86 held by the triumvirate of Intel, AMD and VIA Technologies. Details are also emerging that outline how AMD has managed to stay within the boundaries of the x86 licensing agreements but still allow Chinese-controlled interests to design and sell processors based on the Zen design.

AMD's official statements indicate the company does not sell its final chip designs to its China-based partners. Instead, AMD allows them to design their own processors tailored for the Chinese server market. But the China-produced Hygon "Dhyana" processors are so similar to AMD's EPYC processors that Linux kernel developers have listed vendor IDs and family series numbers as the only difference. In fact, Linux maintainers have simply ported over the EPYC support codes to the Dhyana processor and note that they have successfully run the same patches on AMD's EPYC processors, implying there is little to no differentiation between the chips.

As Cryptocurrency Values Plummet, Graphics Card Pricing Improves Dramatically (hothardware.com) 242

MojoKid writes: In recent months, the cryptocurrency industry has taken a sharp downturn in valuations of virtually all major currencies, from Bitcoin to Ethereum. As a result, cryptocurrency mining itself has become significantly less lucrative for the average miner. In addition, demand on GPUs from the major OEM suppliers like NVIDIA and AMD, has fallen off dramatically as well. Cryptocurrency miner demand for graphics cards has fallen so much so, that pricing of board partner brands like EVGA, Asus, MSI, Gigabyte and others, has returned basically to MSRP levels. This is compared to the sharp price gouging that was going on earlier in 2018 and late last year, when demand was far out-stripping supply. In fact, reports are emerging now that another approximate 20 percent price drop could be coming to GPUs this month, especially as NVIDIA is expected to launch its next generation gaming graphics card very soon. Whether or not this is indicative of some sort of cryptocurrency bubble burst remains to be seen. However, for now, gamers and PC enthusiasts are likely breathing a sigh of relief, as better supply/demand dynamics are clearly in sight.

Laptop Vendors Are Left Sitting On the Sidelines Waiting For the Next Waltz To Start (pcper.com) 87

An anonymous reader shares a report: Intel's delayed release of a new processor is going to have a noticeable effect on the laptop market this year. As there is little chance of seeing anything new until towards the end of this year, laptop designers will not be able to offer new models for the holidays and will instead have to rework existing products. DigiTimes suggests we will see trimmed down models with lower price tags to try to entice consumers into purchasing something, as they expect lower demand than we saw last year. Hopefully some gaming machines may become more affordable, or we will start to see models incorporating AMD's new chips become more common.

Nvidia Looks To Gag Journalists With Multi-Year Blanket NDAs (hardocp.com) 126

The German website Heise reports that Nvidia's new non-disclosure agreements (NDAs) last for five years and are more far reaching than product-specific information. HardOCP explains what NDAs are and shares an excerpt from Heise's report: First and foremost, I should tell you that NDAs in the tech world are nothing new, but those non-disclosure agreements usually are product-specific and date-specific. Say we agree to get a review sample of video card X. Many times we will get an NDA that is specific to releasing any information shared by card X's representative and a date when we can share that information with you, often referred to as the "embargo date."

[Here's the excerpt from Heise about Nvidia's new NDA]: "The NDA should apply to all information provided by Nvidia, so it did not refer to a specific product or information. There was also no concrete expiration date. It was also full of conditions that ran counter to journalistic principles. Our legal department clapped their hands over their heads as they read the document. In other words, journalists are allowed to write only what fits Nvidia in the junk. In doing so, Nvidia downgrades the independent press into a marketing tool."
There are several forums discussing Nvidia's new NDA. HardOCP has shared a copy of the NDA for you to read and make up your own mind.

Intel Is in an Increasingly Bad Position in Part Because It Has Been Captive To Its Integrated Model (stratechery.com) 238

Once one of the Valley's most important companies, Intel is increasingly finding itself in a bad position, in part because of its major bet on integration model. Ben Thompson, writing for Stratechery: When Krzanich was appointed CEO in 2013 it was already clear that arguably the most important company in Silicon Valley's history was in trouble: PCs, long Intel's chief money-maker, were in decline, leaving the company ever more reliant on the sale of high-end chips to data centers; Intel had effectively zero presence in mobile, the industry's other major growth area. [...] [Analyst] Ben Bajarin wrote last week in Intel's Moment of Truth. As Bajarin notes, 7nm for TSMC (or Samsung or Global Foundries) isn't necessarily better than Intel's 10nm; chip-labeling isn't what it used to be. The problem is that Intel's 10nm process isn't close to shipping at volume, and the competition's 7nm processes are. Intel is behind, and its insistence on integration bears a large part of the blame.

The first major miss [for Intel] was mobile: instead of simply manufacturing ARM chips for the iPhone the company presumed it could win by leveraging its manufacturing to create a more-efficient x86 chip; it was a decision that evinced too much knowledge of Intel's margins and not nearly enough reflection on the importance of the integration between DOS/Windows and x86. Intel took the same mistaken approach to non general-purpose processors, particularly graphics: the company's Larrabee architecture was a graphics chip based on -- you guessed it -- x86; it was predicated on leveraging Intel's integration, instead of actually meeting a market need. Once the project predictably failed Intel limped along with graphics that were barely passable for general purpose displays, and worthless for all of the new use cases that were emerging. The latest crisis, though, is in design: AMD is genuinely innovating with its Ryzen processors (manufactured by both GlobalFoundries and TSMC), while Intel is still selling varations on Skylake, a three year-old design.

Nvidia Appears To Have A GPU Inventory Problem (seekingalpha.com) 83

Reports out of Taiwan now suggest that Nvidia has a gaming GPU inventory problem. An anonymous reader writes: Tech news site SemiAccurate which covers the GPU space pretty closely, and has broken stories like AMD's acquisition of ATI Technologies and Nvidia's Bumpgate, just published an article on why Nvidia has delayed their new gaming GPUs. It seems the Hot Chips 30 agenda cancellation and Jensen's no new GPUs for 'a long time' comment have created enough of a stir to get journalists and industry insiders asking questions. While curiosity amongst all this confusion is natural, I was surprised to discover that people were starting to speculate Nvidia's delay was due to technical issues with their new GPUs. This had never been a concern of mine, and as it turns out, it's clearly not the case. So, what the problem? Nvidia has overestimated pent-up gaming demand and underestimated the impact of declining mining demand.

Shots Fired Again Between CPU Vendors AMD and Intel (tomshardware.com) 146

Highdude702 shares a report from Tom's Hardware: AMD's feud with Intel took an interesting turn today as the company announced that it would swap 40 Core i7-8086K's won from Intel's sweepstakes with a much beefier Threadripper 1950X CPU. At Computex 2018, Intel officially announced it was releasing the Core i7-8086K, a special edition processor that commemorates the 40th anniversary of the 8086, which debuted as the first x86 processor on June 8, 1978. Now AMD is offering to replace 40 of the winners' chips with its own 16-core 32-thread $799 Threadripper processors, thus throwing a marketing wrench into Intel's 40th-anniversary celebration.

AMD has a list of the complete terms and conditions on its site. But it is also noteworthy that "winners" of AMD's competing sweepstakes will have to pony up for a much more expensive X399 motherboard with the TR4 socket, which currently retail for more than $300, instead of Intel's less-expensive 300-series motherboards. Regardless, those who do swap their Intel Core silicon for an AMD Threadripper chip will gain 10 cores and quad-channel memory, not to mention quite a bit of resale value.
In response, Slashdot reader Highdude702 said: "AMD is shooting back at Intel like its easy for them, even though 40 out of 8086 is kind of stingy. They are acting like they have the horsepower now. I believe it is going to be an interesting time for consumers and enthusiasts coming soon. Maybe we will even get better prices."

Intel responded via its official verified "Intel Gaming" Twitter account, tweeting: ".@AMDRyzen, if you wanted an Intel Core i7-8086K processor too, you could have just asked us. :) Thanks for helping us celebrate the 8086!"

Sony's PlayStation 5 Will Launch In 2020 Powered By An AMD Navi GPU, Says Report (theinquirer.net) 95

According to a new report from WCCFtech, citing "sources familiar with the entire situation," Sony's PlayStation 5 (PS5 for short) will launch in 2020 and be powered by AMD's Navi GPU chip. "While it was previously reported that the much-anticipated console will be using AMD's Ryzen CPU tech, it looks like the chip maker will have some involvement in the PS5's graphics chip, too," reports The Inquirer. From the report: The report also suggests this is the reason behind AMD not announcing a new GPU at Computex this year, because it has found custom-applications for consoles a much more financially attractive space. "Here is a fun fact: Vega was designed primarily for Apple and Navi is being designed for Sony - the PS5 to be precise," the report states, right before going on to explain AMD's roadmap for Navi and how it's dependent on Sony.

"This meant that the graphics department had to be tied directly to the roadmap that these semi-custom applications followed. Since Sony needed the Navi GPU to be ready by the time the PS5 would launch (expectedly around 2020) that is the deadline they needed to work on."
It's anyone's guess as to when the successor to the PlayStation 4 will be launched. While the source for this report is seen as reputable in the games industry, last month the head of PlayStation business said the next console is three years off.

Another Day, Another Intel CPU Security Hole: Lazy State (zdnet.com) 110

Steven J. Vaughan-Nichols, writing for ZDNet: The latest Intel revelation, Lazy FP state restore, can theoretically pull data from your programs, including encryption software, from your computer regardless of your operating system. Like its forebears, this is a speculative execution vulnerability. In an interview, Red Hat Computer Architect Jon Masters explained: "It affects Intel designs similar to variant 3-a of the previous stuff, but it's NOT Meltdown." Still, "it allows the floating point registers to be leaked from another process, but alas that means the same registers as used for crypto, etc." Lazy State does not affect AMD processors.

This vulnerability exists because modern CPUs include many registers (internal memory) that represent the state of each running application. Saving and restoring this state when switching from one application to another takes time. As a performance optimization, this may be done "lazily" (i.e., when needed) and that is where the problem hides. This vulnerability exploits "lazy state restore" by allowing an attacker to obtain information about the activity of other applications, including encryption operations.

Laptops With 128GB of RAM Are Here (theverge.com) 364

An anonymous reader quotes a report from The Verge: Brace yourself for laptops with 128GB of RAM because they're coming. Today, Lenovo announced its ThinkPad P52, which, along with that massive amount of memory, also features up to 6TB of storage, up to a 4K, 15.6-inch display, an eighth-gen Intel hexacore processor, and an Nvidia Quadro P3200 graphics card. The ThinkPad also includes two Thunderbolt three ports, HDMI 2.0, a mini DisplayPort, three USB Type-A ports, a headphone jack, and an Ethernet port. The company hasn't announced pricing yet, but it's likely going to try to compete with Dell's new 128GB-compatible workstation laptops. The Dell workstation laptops in question are the Precision 7730 and 7530, which are billed as "ready for VR" mobile workstations. According to TechRadar, "These again run with either 8th-gen Intel CPUs or Xeon processors, AMD Radeon WX or Nvidia Quadro graphics, and the potential to specify a whopping 128GB of 3200MHz system memory."

Intel Says Its First Discrete Graphics Chips Will Be Available in 2020 (marketwatch.com) 99

Ryan Shrout, reporting for MarketWatch: Intel CEO Brian Krzanich disclosed during an analyst event last week that it will have its first discrete graphics chips available in 2020. This will mark the beginning of the chip giant's journey toward a portfolio of high-performance graphics products for various markets including gaming, data center and artificial intelligence (AI). Some previous rumors suggested a launch at CES 2019 this coming January might be where Intel makes its graphics reveal, but that timeline was never adopted by the company. It would have been overly aggressive and in no way reasonable with the development process of a new silicon design. In November 2017 Intel brought on board Raja Koduri to lead the graphics and compute initiatives inside the company. Koduri was previously in charge of the graphics division at AMD helping to develop and grow the Radeon brand, and his departure to Intel was thought to have significant impact on the industry.

'We've an Unexpected Manufacturing Advantage For the First Time Ever': Intel's Manufacturing Glitch Opens Door For AMD (theinformation.com) 136

Over at The Information (paywalled), reporter Aaron Tilley has a splendid interview of Forrest Norrod, a senior executive who joined AMD four years ago. Mr. Norrod describes the challenge AMD has faced over the years and how, for the first time ever, it sees a real shot at making a significant dent in the desktop market. From the report: Advanced Micro Devices' battle with chip giant Intel has often seemed like a gnat fighting an elephant, with AMD struggling in recent years to gain even a tenth of the market for the chips that power PCs and data center servers. Forrest Norrod, a senior executive who joined AMD four years ago, says the company suffered from "little brother syndrome" where it tried and failed to compete with Intel on lots of different chips. Now, though, AMD may have a shot at coming out with a faster, more powerful chip than Intel for the first time. Intel in April said it was delaying the release of a more advanced chip manufacturing process until sometime in 2019. AMD has its own new, advanced chip, which it will now be able to release earlier than Intel, potentially giving it an edge in the market for high-performance chips for PCs and data center computers.

It's a market opportunity worth around $50 billion. That's what Intel makes from selling chips for PCs and data center servers, and it dominates both markets. The data center market is particularly important because of the growth of new technologies like artificial intelligence-related applications, much of which is handled in the cloud. Companies that buy chips for data centers or PCs could gravitate to AMD chips as a result of Intel's delay. "I think we have a year lead now," said Mr. Norrod, who oversees AMD's data center business. AMD now has "an unexpected [manufacturing] advantage for the first time ever," he added.

Researchers Crack Open AMD's Server VM Encryption (theregister.co.uk) 50

Shaun Nichols, reporting for The Register: A group of German researchers have devised a method to thwart the VM security in AMD's server chips. Dubbed SEVered (PDF), the attack would potentially allow an attacker, or malicious admin who had access to the hypervisor, the ability to bypass AMD's Secure Encrypted Virtualization (SEV) protections.

The problem, say Fraunhofer AISEC researchers Mathias Morbitzer, Manuel Huber, Julian Horsch and Sascha Wessel, is that SEV, which is designed to isolate VMs from the prying eyes of the hypervisor, doesn't fully isolate and encrypt the VM data within the physical memory itself.
