AMD Just Leaked Its Nvidia RTX Voice Competitor in a (Now Deleted) Video (theverge.com) 8

AMD looks to be on the cusp of releasing a competitor to RTX Voice, a feature for Nvidia graphics cards that cancels out background noise when you're on a call or otherwise using your mic. From a report: That's according to a trailer that AMD posted to its YouTube channel (apparently in error), Tom's Hardware reports. Thankfully, a copy of the trailer was downloaded before it was deleted by Reddit user u/zenobian and uploaded to the AMD subreddit. The leaked trailer suggests that AMD's Noise Suppression feature will work very similarly to Nvidia's RTX Voice (which has subsequently been rolled into Nvidia's Broadcast app). It uses "a real-time deep learning algorithm" to offer "two-way noise-reduction" that filters background noise out of both outgoing and incoming microphone audio, and is apparently built into AMD's existing Adrenalin software.

How the FSF Runs Using Nothing But Freedom-Respecting BIOS (fsf.org) 54

A senior systems administrator at the Free Software Foundation points out that they're running free software in two data centers and over a hundred virtual machine — each and every one with "a freedom-respecting BIOS."

But the "how" is surprisingly intricate: [E]arlier this week, we replaced "Columbia", the last of any FSF-run machines running a nonfree BIOS....

At FSF, our current standard is ASUS KGPE-D16 motherboards with AMD CPUs 6200 series CPUs released in 2012. For the BIOS, we install Libreboot, the easy-to-install, 100% free software replacement for proprietary BIOS/boot programs, or a version of Coreboot that is carefully built to avoid including any nonfree blobs. They are fast enough for our needs, and we expect this to be the case for many more years to come. They are also very affordable systems. We are also working toward supporting Raptor Computer Systems' newer and more powerful Talos II, as well as Blackbird motherboards that use IBM POWER9 CPUs. The POWER9 CPU architecture is called "PowerPC 64-bit little endian," abbreviated "ppc64el...." The Raptor motherboards come with entirely free firmware — and even have free hardware designs!

However, this type of migration has its challenges. For example, the first thing we needed to address before using these motherboards is that the main operating system we use, Trisquel GNU/Linux, didn't previously run on pp64el. So, earlier this year, we set up a Raptor POWER9 computer running Debian (without using any nonfree parts of Debian repositories) and loaned it to the maintainers of Trisquel for as long as needed. And now, we are proud to say that the upcoming Trisquel 11 release will support POWER9...!

Before I decommissioned Columbia, I ran a dmidecode, which told me that the BIOS program fit within a single megabyte of space. Often, very simplistic firmware becomes more complicated in later models, and that also usually means it has a growing significance for a user's software freedom. Some newer nonfree BIOSes have grown into operating systems in their own right, sometimes with large programs such as a full Web browser.

There is no fully-free BIOS available for x86 Intel and AMD CPUs released after about 2013. The key blocking factor is that those CPUs require certain firmware in the BIOS, like Intel Management Engine. Those CPUs will also refuse to run firmware that hasn't been cryptographically signed by private keys controlled by AMD and Intel, and AMD and Intel will only sign their own nonfree firmware. At the FSF, we refuse to run that nonfree firmware, and we applaud the many people who also avoid it. For those people who do run those Intel or AMD systems, running Coreboot or Osboot is still a step up the Freedom Ladder for the software freedom of your BIOS.

The road to freedom is a long road. We hope our dedication to achieve milestones like these can inspire the free software movement.

Lenovo Patches UEFI Code Execution Vulnerability Affecting More Than 70 Laptop Models (securityweek.com) 20

Lenovo has released a security advisory to inform customers that more than 70 of its laptops are affected by a UEFI/BIOS vulnerability that can lead to arbitrary code execution. SecurityWeek reports: Researchers at cybersecurity firm ESET discovered a total of three buffer overflow vulnerabilities that can allow an attacker with local privileges to affected Lenovo devices to execute arbitrary code. However, Lenovo says only one of the vulnerabilities (CVE-2022-1892) impacts all devices, while the other two impact only a handful of laptops. "The vulnerabilities can be exploited to achieve arbitrary code execution in the early phases of the platform boot, possibly allowing the attackers to hijack the OS execution flow and disable some important security features," ESET explained. "These vulnerabilities were caused by insufficient validation of DataSize parameter passed to the UEFI Runtime Services function GetVariable. An attacker could create a specially crafted NVRAM variable, causing buffer overflow of the Data buffer in the second GetVariable call," it added.

Lenovo has also informed customers about Retbleed, a new speculative execution attack impacting devices with Intel and AMD processors. The company has also issued an advisory for a couple of vulnerabilities affecting many products that use the XClarity Controller server management engine. These flaws can allow authenticated users to cause a DoS condition or make unauthorized connections to internal services.

New Working Speculative Execution Attack Sends Intel and AMD Scrambling (arstechnica.com) 66

Some microprocessors from Intel and AMD are vulnerable to a newly discovered speculative execution attack that can covertly leak password data and other sensitive material, sending both chipmakers scrambling once again to contain what is proving to be a stubbornly persistent vulnerability. Ars Technica reports: Researchers from ETH Zurich have named their attack Retbleed because it exploits a software defense known as retpoline, which was introduced in 2018 to mitigate the harmful effects of speculative execution attacks. Speculative execution attacks, also known as Spectre, exploit the fact that when modern CPUs encounter a direct or indirect instruction branch, they predict the address for the next instruction they're about to receive and automatically execute it before the prediction is confirmed. Spectre works by tricking the CPU into executing an instruction that accesses sensitive data in memory that would normally be off-limits to a low-privileged application. Retbleed then extracts the data after the operation is canceled. [...] The ETH Zurich researchers have conclusively shown that retpoline is insufficient for preventing speculative execution attacks. Their Retbleed proof-of-concept works against Intel CPUs with the Kaby Lake and Coffee Lake microarchitectures and AMD Zen 1, Zen 1+, and Zen 2 microarchitectures.

In response to the research, both Intel and AMD advised customers to adopt new mitigations that the researchers said will add as much as 28 percent more overhead to operations. [...] Both Intel and AMD have responded with advisories. Intel has confirmed that the vulnerability exists on Skylake-generation processors that don't have a protection known as enhanced Indirect Branch Restricted Speculation (eIBRS) in place. "Intel has worked with the Linux community and VMM vendors to provide customers with software mitigation guidance which should be available on or around today's public disclosure date," Intel wrote in a blog post. "Note that Windows systems are not affected given that these systems use Indirect Branch Restricted Speculation (IBRS) by default which is also the mitigation being made available to Linux users. Intel is not aware of this issue being exploited outside of a controlled lab environment." AMD, meanwhile, has also published guidance. "As part of its ongoing work to identify and respond to new potential security vulnerabilities, AMD is recommending software suppliers consider taking additional steps to help guard against Spectre-like attacks," a spokesman wrote in an email. The company has also published a whitepaper.

[Research Kaveh Razavi added:] "Retbleed is more than just a retpoline bypass on Intel, specially on AMD machines. AMD is in fact going to release a white paper introducing Branch Type Confusion based on Retbleed. Essentially, Retbleed is making AMD CPUs confuse return instructions with indirect branches. This makes exploitation of returns very trivial on AMD CPUs." The mitigations will come at a cost that the researchers measured to be between 12 percent and 28 percent more computational overhead. Organizations that rely on affected CPUs should carefully read the publications from the researchers, Intel, and AMD and be sure to follow the mitigation guidance.

Magic Leap 2 AR Headset Arrives Sept 30, Starting at $3,299 (cnet.com) 26

Magic Leap's next AR headset is coming this fall, and it's not cheap. The self-contained Magic Leap 2 glasses, which CNET tried earlier this year, will cost at least $3,299, and be available Sept. 30. From a report: Unlike the first Magic Leap headset, which launched back in 2018 and aspired to be for creative consumers, the Magic Leap 2 is entirely business-focused. The smaller glasses have their own dedicated AMD hip-worn processor puck. They offer a wider field of view than any other AR headset we've tried recently, and a unique feature that dims parts of the real world to make virtual objects seem less ghostly. The headset will come in three variations: the $3,299 Magic Leap 2 Base is the hardware plus a one-year warranty; while the Magic Leap 2 Developer Pro comes with extra developer-focused software and sample projects for $4,099. A Magic Leap 2 Enterprise version, with two-year support for enterprise-ready software, costs $4,999. Magic Leap's website will indicate where headsets will be available to buy: in the US, UK, Germany, France, Spain, Italy and Saudi Arabia on Sept. 30, and Japan and Singapore by the end of the year.

Six Ground-Breaking New Linux Laptops Released in the Last Two Weeks (beehiiv.com) 84

In the last two weeks, six new Linux laptops have hit the market (or were announced). "The Linux hardware scene is getting better by the day," writes the site FOSS Weekly:
  • MNT Research introduces a "more affordable" 7-inch mini Linux laptop, the MNT Pocket Reform.
  • KDE's Slimbook 4 is here with AMD Ryzen 7 5700U processor and a better battery, starting from $1,000. "Buying from Slimbook supports KDE development too," notes Gaming on Linux, adding that there's a choice of 14 or 15.6 inch displays.
  • TUXEDO's Pulse 15 — Gen2 (also with an AMD Ryzen 7 5700U processor) has a 15-inch HiDPI WQHD 165Hz display, along with eight cores and 16 threads. (And the Register notes its twin cooling fans, "allowing them to overclock the chip and run it at 35W," and a choice of distros.)
  • Pre-orders have opened for the Roma — the first RISC-V Laptop (which may ship in September). Ars Technica reports they're offering "free Silicon upgrades" — that is free system-on-a-chip and system-on-module upgrades for its quad-core RISC-V CPU. And there's also a companion NPU/GPU, notes a blog post at RISCV.org, "for the fastest, seamless RISC-V native software development available." (As well as "early access to next-generation laptop and accessory upgrades at generous discounts or for free.") The blog post calls it a "Web3-friendly platform with NFT creation and publication plus integrated MetaMask-style wallet."

TSMC May Surpass Intel In Quarterly Revenue For First Time (theregister.com) 9

Wall Street analysts estimate TSMC will grow second-quarter revenue 43 percent quarter-over-quarter to $18.1 billion. Intel, on the other hand, is expected to see sales decline 2 percent sequentially to $17.98 billion in the same period, according to estimates collected by Yahoo Finance. The Register reports: The potential for TSMC to surpass Intel in quarterly revenue is indicative of how demand has grown for contract chip manufacturing, fueled by companies like Qualcomm, Nvidia, AMD, and Apple who design their own chips and outsource manufacturing to foundries like TSMC. This trend has created a quandary for Intel. The semiconductor giant has traditionally manufactured the chips it designs as part of its integrated device manufacturing model but the company is now increasingly reliant on TSMC and other foundries for certain components, while expanding its own manufacturing capacity in the West.

The kicker is that Intel plans to use this increased capacity to produce more of its own chips while also supporting its revitalized foundry business, which hopes to take business from TSMC and South Korea's Samsung, the industry's other leading-edge chipmaker, in the future. This new strategy by Intel is called IDM 2.0, and it means the chipmaker will have to juggle two somewhat conflicting objectives:

- taking foundry market share away from TSMC and Samsung by convincing various fabless chip designers to use its plants;
- and using leading-edge nodes from TSMC and Samsung for certain components to compete with fabless companies like AMD and Nvidia.
"Samsung has already surpassed Intel as the largest semiconductor company by revenue, so TSMC potentially growing larger than the x86 giant further underscores the tentative position Intel is in," concludes the report.

RansomHouse Extortion Group Claims AMD as Its Latest Victim (techcrunch.com) 16

AMD said it is investigating a potential data breach after RansomHouse, a relatively new data cybercrime operation, claims to have extorted data from the U.S. chipmaker. From a report: An AMD spokesperson told TechCrunch that the company "is aware of a bad actor claiming to be in possession of stolen data," adding that "an investigation is currently underway." RansomHouse, which earlier this month claimed responsibility for a cyberattack on Shoprite, Africa's largest retailer, claims to have breached AMD on January 5 to steal 450 GB of data. The group claims to be targeting companies with weak security, and claimed it was able to compromise AMD due to the use of weak passwords throughout the organization.

"An era of high-end technology, progress and top security... there's so much in these words for the crowds. But it seems those are still just beautiful words when even technology giants like AMD use simple passwords to protect their networks from intrusion," RansomHouse wrote on its data leak site. "It is a shame those are real passwords used by AMD employees, but a bigger shame to AMD Security Department which gets significant financing according to the documents we got our hands on -- all thanks to these passwords." Brett Callow, a ransomware expert and threat analyst at Emsisoft, told TechCrunch there's no reason to doubt the group's claims.

Intel Just Asked the EU For $624 Million To Pay It Back For Overturned Anti-AMD Fine (pcgamer.com) 46

Intel is seeking to be paid interest of $624 million on the overturned $1.1 billion fine it received from the European Commission back in 2009. From a report: The antitrust ruling was overturned at the beginning of the year, and so Intel has gone to EU General Court seeking compensation and interest on the fine. In fact, Intel is claiming back almost half of that original fine, based on the European Central Bank's refinancing rates. In case you need a reminder on all of this: Intel allegedly took part in anti-competitive practices that saw it offer conditional rebates to key OEMs such as Dell, HP, and Lenovo, making it difficult for competitors (read AMD, or ARM if you prefer, but really AMD) to compete with their own CPUs. The European Commission concluded in 2009 that Intel had indeed behaved in such a way between October 2002 and December 2007 and hit it with one of the largest ever fines at the time at a cool $1.1 billion. Intel appealed the decision unsuccessfully in 2012, but in 2014 it brought the case to the European Court of Justice, which sent it back to the General Court in 2017. The case has been going back and fourth ever since.

A New Vulnerability in Intel and AMD CPUs Lets Hackers Steal Encryption Keys (arstechnica.com) 30

Microprocessors from Intel, AMD, and other companies contain a newly discovered weakness that remote attackers can exploit to obtain cryptographic keys and other secret data traveling through the hardware, researchers said on Tuesday. From a report: Hardware manufacturers have long known that hackers can extract secret cryptographic data from a chip by measuring the power it consumes while processing those values. Fortunately, the means for exploiting power-analysis attacks against microprocessors is limited because the threat actor has few viable ways to remotely measure power consumption while processing the secret material. Now, a team of researchers has figured out how to turn power-analysis attacks into a different class of side-channel exploit that's considerably less demanding.

The team discovered that dynamic voltage and frequency scaling (DVFS) -- a power and thermal management feature added to every modern CPU -- allows attackers to deduce the changes in power consumption by monitoring the time it takes for a server to respond to specific carefully made queries. The discovery greatly reduces what's required. With an understanding of how the DVFS feature works, power side-channel attacks become much simpler timing attacks that can be done remotely. The researchers have dubbed their attack Hertzbleed because it uses the insights into DVFS to expose -- or bleed out -- data that's expected to remain private. The vulnerability is tracked as CVE-2022-24436 for Intel chips and CVE-2022-23823 for AMD CPUs. The researchers have already shown how the exploit technique they developed can be used to extract an encryption key from a server running SIKE, a cryptographic algorithm used to establish a secret key between two parties over an otherwise insecure communications channel.

AMD Details RDNA 3 Graphics, Zen 4 Performance and Phoenix Point Laptop Products (hothardware.com) 16

Slashdot reader MojoKid writes: AMD unveiled new details of its technology roadmap Thursday at its 2022 Financial Analyst Day. Chief among them were disclosures on the company's next-gen RDNA 3 GPU architecture, Zen 4 CPU architecture and Phoenix Point laptop SoC. AMD's new RDNA 3 GPU architecture for Radeon graphic cards and mobile will be a chiplet-based design, much like the company's Ryzen CPU offering. AMD also confirmed that RDNA 3 GPUs would be fabricated on a 5nm process, likely TSMC N5. The company continued to note that an "optimized graphics pipeline" will enable yet higher clock rates, while the GPU's "rearchitected compute unit" will have ray-tracing performance improvements over RDNA 2 as well. AMD says that RDNA 3 GPUs are coming later this year, with RDNA 4 arriving likely in late 2023.

Meanwhile, AMD's Zen 4 is set to be the "world's first 5nm CPU," arriving later this year with an 8 to 10 percent instructrions per clock lift and greater than 15 percent single-threaded performance gain. Zen 4 will also support DDR5, AVX-512 extensions for AI workloads and a massive 125 percent increase in memory bandwidth. AMD is claiming a 35% multithreaded performance lift for Zen 4.

And, its Phoenix Point laptop platform SoC will be both Zen 4 and RNDA 3 infused. This is a first for AMD, since typically its laptop product's integrated graphics trail the company's current-gen GPU architecture by at least a generation. Phoenix point is set to arrive likely in the first half of 2023.

Apple Will Allow Linux VMs To Run Intel Apps With Rosetta In macOS Ventura (arstechnica.com) 35

An anonymous reader quotes a report from Ars Technica: One of the few things that Intel Macs can do that Apple Silicon Macs can't is run operating systems written for Intel or AMD processors inside of virtual machines. Most notably, this has meant that there is currently no legal way to run Windows on an Apple Silicon Mac. Apple Silicon Macs can, however, run operating systems written for Arm processors inside of virtual machines, including other versions of macOS and Arm-compatible versions of Linux. And those Linux VMs are getting a new feature in macOS Ventura: the ability to run apps written for x86 processors using Rosetta, the same binary translation technology that allows Apple Silicon Macs to run apps written for Intel Macs.

Apple's documentation will walk you through the requirements for using Rosetta within a Linux guest operating system -- it requires creating a shared directory that both macOS and Linux can access and running some terminal commands in Linux to get it set up. But once you do those steps, you'll be able to enjoy the wider app compatibility that comes with being able to run x86 code as well as Arm code. Some developers, including Hector Martin of the Asahi Linux project and Twitter user @never_released, have already found that these steps can also enable Rosetta on non-Apple ARM CPUs as long as they're modern enough to support at least version 8.2 of the Arm instruction set. As Martin points out, this isn't strictly legal because of macOS's licensing restrictions, and there are some relatively minor Apple-specific hardware features needed to unlock Rosetta's full capabilities.

Apple's New MetalFX Upscaling System Will Compete With AMD FSR, Nvidia DLSS (arstechnica.com) 44

At this year's WWDC, Apple announced a surprising new system coming to its Metal 3 gaming API that may sound familiar to PC gamers: MetalFX Upscaling. Ars Technica reports: The system will leverage Apple's custom silicon to reconstruct video game graphics using lower-resolution source images so that games can run more efficiently at lower resolutions while looking higher-res. This "temporal reconstruction" system sounds similar to existing offerings from AMD (FidelityFX Super Resolution 2.0) and Nvidia (Deep Learning Super-Sampling), along with an upcoming "XeSS" system from Intel. Based on how the system is described, it will more closely resemble AMD's system, since Apple has yet to announce a way for MetalFX Upscaling to leverage its custom-made "Neural Engine" system.

By announcing this functionality for some of the world's most popular processors, Apple is arguably letting more game developers build their games and engines with image reconstruction -- even if MetalFX Upscaling isn't open source, unlike AMD's FSR 2.0 system. Still, these image reconstruction systems typically have temporal anti-aliasing (TAA) in common. So long as game devs keep that kind of anti-aliasing in mind with their games and engines, they'll be more likely to take advantage and thus run more efficiently on a wide range of consoles, computers, and smartphones.
The report notes that Metal 3 also includes "a new 'resource-loading' API designed to streamline asset-loading processes in video games." The same Metal 3 API benefits will also come to iPadOS 16 later this year.

'Doom' Game Ported To Run As a Coreboot BIOS Payload (phoronix.com) 17

"Yes, it's possible to get the game Doom running atop this system firmware," reports Phoronix.

Tom's Hardware explains: Originally known as LinuxBIOS, which provides a better clue to its utility value, Coreboot 4.17 supports new motherboards, delivers a new bootloader, supports AMD Platform Secure Boot (PSB), comes with a handful of fixes, and... a port of Doom.

Coreboot is a free and open-source BIOS implementation that supports numerous extensions known as Payloads. These Payloads add functionality to the minimal code that is the basis of Coreboot. Therefore, a great deal of customizability is available to Coreboot users to determine exactly what their BIOS ROMs contain via Payload choices.

To configure Coreboot for a usable setup, one might typically start by adding a bootloader, with a choice of eight available currently according to the official Wiki. Then there is support for various popular OSes, a handful of utilities provided as Payloads, and even some games. If your BIOS flash memory space is large enough, you could even shoehorn in a Linux distribution.

There's a few caveats. (There's no sound or "save game" feature, "and your system will hang on exiting the game.")

But their article still calls Doom "a great new choice if you are bored of the Grub Invaders (Space Invaders) and Tint (Tetris) clone Payloads, bringing 3D gaming to your BIOS."

HP Dev One Laptop Running System76's Ubuntu Linux-based Pop!_OS Now Available (betanews.com) 54

An anonymous reader shares a report: Last month, the open source community was abuzz with excitement following a shocking announcement from System76 that HP was planning to release a laptop running the Pop!_OS operating system. This was significant for several reasons, but most importantly, it was a huge win for Linux users as yet another hardware option was becoming available. Best of all, HP employees have been trained by System76 to offer high-quality customer support. If you aren't aware, System76 support is legendary.

At the time of the announcement, details about the hardware were a bit scarce, but I am happy to report we now have full system specifications for the 14-inch HP Dev One laptop. Most interestingly, there is only one configuration to be had. The developer-focused computer is powered by an octa-core AMD Ryzen 7 PRO 5850U APU which features integrated Radeon graphics. The notebook comes with 16GB RAM and 1TB of NVMe storage, both of which can be user-upgraded later if you choose.
The laptop is priced at $1,099.

US Retakes First Place From Japan on Top500 Supercomputer Ranking (engadget.com) 29

The United States is on top of the supercomputing world in the Top500 ranking of the most powerful systems. From a report: The Frontier system from Oak Ridge National Laboratory (ORNL) running on AMD EPYC CPUs took first place from last year's champ, Japan's ARM A64X Fugaku system. It's still in the integration and testing process at the ORNL in Tennessee, but will eventually be operated by the US Air Force and US Department of Energy. Frontier, powered by Hewlett Packard Enterprise's (HPE) Cray EX platform, was the top machine by a wide margin, too. It's the first (known) true exascale system, hitting a peak 1.1 exaflops on the Linmark benchmark. Fugaku, meanwhile, managed less than half that at 442 petaflops, which was still enough to keep it in first place for the previous two years. Frontier was also the most efficient supercomputer, too. Running at just 52.23 gigaflops per watt, it beat out Japan's MN-3 system to grab first place on the Green500 list. "The fact that the world's fastest machine is also the most energy efficient is just simply amazing," ORNL lab director Thomas Zacharia said at a press conference.

'Why Won't Corsair and Dell Just Let Apple's Touch Bar Die Already?' (macworld.com) 86

An anonymous reader shares an excerpt from an opinion piece, written by Macworld's Michael Simon: Apple killed its Touch Bar on the 14-inch and 16-inch MacBook Pro last year, but PC makers seem determined to prove the company wrong. First Dell introduced the XPS 13 Plus which sports a "new capacitive touch experience that allows you to switch between media and function keys easily." The laptop is available for purchase but back-ordered for weeks, and there haven't been any reviews so we don't know for sure how it will be received, but Dell's touch bar concept seems even less useful than Apple's: the buttons are static, they merely float above the actual keyboard, and they don't appear to add any functionality. Then Dell added a touch bar to the trackpad on the Latitude 9330. [...]

Now there's a new PC touch bar, this time on the Voyager a1600, Corsair's first-ever gaming laptop. Corsair hasn't named or even officially announced the new feature -- it only appeared as a sneak peek -- but the company told The Verge that the strip features "10 easy-access customizable S-key shortcut buttons." [...] Corsair's Touch Bar doesn't replace the row of function keys but it is in an odd location -- on the hinge below the display. Even in pictures, it looks incredibly uncomfortable to reach. According to renders, you can still access the Touch Bar when the laptop is closed, which seems like an accident waiting to happen (not to mention a battery drain).

But the biggest question I have is: why? No one shed a tear for the Touch Bar when it was killed. While it has its merits, it was never a proper pro-level feature and the implementation didn't evolve past the original idea. It was too skinny, lacked tactile feedback, required constant scrolling, and didn't actually save time. It looked nice, but even Apple didn't seem to know what to do with it. The MacBook Pro Touch Bar was one of Apple's most polarizing features and it never really caught on with developers. Maybe a niche use like gaming or video conferencing will have better results, but ultimately the Touch Bar, Apple's or otherwise, is a failed concept that should stay in the past.

Samsung Allegedly Assembling a 'Dream Team' To Take Down Apple's M1 In 2025 (neowin.net) 47

Samsung is rumored to be assembling a special task force dubbed "Dream Platform One team" tasked with designing a custom in-house Samsung mobile Application Processor (AP) that can take on Apple Silicon. Neowin reports: It's probably fair to say that Samsung hasn't had the best time with its Exynos offerings when compared against rivals like Qualcomm or Apple. To shake its fortunes up, the company also paired up with AMD for its Exynos 2200 GPU, and results were a mixed bag. Both the AMD RDNA 2 Xclipse 920 graphics and the Exynos 2200 CPU were found to be pretty disappointing in terms of power efficiency as they were not much better than the previous Exynos 2100 offering. In a nutshell, the new CPU was around 5% faster while the AMD graphics was around 17% better, both of which were clearly not enough (via TechAltar on Twitter). However, the company is looking to get real serious and down to business come 2025. The new report coincides with a separate report suggesting that Samsung was working on a custom chipset for its Galaxy S series. The downside is that it's not slated for 2025 and will obviously have to compete against whatever Apple offers at that time.

AMD Ryzen 7000 Smokes Alder Lake In Computex Keynote Zen 4 Tease (hothardware.com) 59

"AMD's Computex 2022 keynote marks the first appearance of company's new Zen 4-based Ryzen 7000 desktop chip in the flesh," writes Slashdot reader MojoKid. "And in its first quick benchmark tease, it's looking pretty buff." Here's an excerpt from a report via HotHardware: AMD Ryzen 7000-series processors that will be the first to ship with Zen 4 cores will include one or two 5nm Zen 4 CCDs -- topping out at 16 cores, just like Zen 3 -- as well as a new cIOD fabricated on 6nm chip process technology. The new cIOD will include PCIe 5.0 and DDR5 support, as well as an RDNA 2-based GPU for basic display support. [...] Initial performance claims regarding solid state storage weren't the only ones made during AMD's Computex keynote, however. As the keynote was wrapping up, Dr. Su showed two demos powered by a Ryzen 7000 series processor.

AMD Ryzen 7000-series processors that will be the first to ship with Zen 4 cores will include one or two 5nm Zen 4 CCDs -- topping out at 16 cores, just like Zen 3 -- as well as a new cIOD fabricated on 6nm chip process technology. The new cIOD will include PCIe 5.0 and DDR5 support, as well as an RDNA 2-based GPU for basic display support. In the second demo, a custom Ryzen 7000 3D image was being rendered in Blender, with an Intel Core i9-12900K 16-core / 24-thread processor running alongside an AMD Ryzen 7000 series 16-core / 32-thread processor. In the time-lapsed demo, the Ryzen 7000-based system finished the render 31% faster than the Intel system.

While AMD wasn't willing to commit to any specific date, the company did confirm that Zen 4 will be here this year, and well before the holiday shopping season. Dr. Su set a timeframe of "Fall" for availability of the new Ryzen 7000 CPUs, as well as the motherboards that will help enable the entire platform.
