MojoKid writes from a report via HotHardware: If you've had any doubts of Intel's upcoming Kaby Lake processor's capabilities with respect to overclocking, don't fret. It's looking like even the most dedicated overclockers are going to have a blast with this series. Someone recently got a hold of an Intel Core i7-7700K chip and decided to take it for an overclocking spin. Interestingly, the motherboard used is not one of the upcoming series designed for Kaby Lake, but the chip was instead overclocked on a Z170 motherboard from ASRock (Z170M OC Formula). That bodes well for those planning to snag a Kaby Lake CPU and would rather not have to upgrade their motherboard as well. With liquid nitrogen cooling the processor, this particular chip peaked at just over 7GHz, which helped deliver a SuperPi 32M time of 4m 20s, and a wPrime 1024M time of 1m 33s. It's encouraging to see the chip breaking this clock speed, even with extreme methods, since it's a potential relative indicator of how much headroom will be available for overclocking with more standard cooling solutions.

An anonymous reader shares a report: Data from the builds on PCPartPicker show an interesting trend among the buyers of AMD CPUs. Of the 25,780 builds on PCPartPicker from the last 31 months with a price point between $450âS - $5,000, 19% included an AMD CPU. This is in-line with the Steam Hardware Surveys, but things have changed recently. Builds with AMD CPUs tend to be much less expensive than those with Intel CPUs. The builds with an AMD CPU were $967 on average versus the Intel CPU builds, which were on average $1,570. In the last 31 months, brand loyalty to AMD seemed to push AMD CPU builders to choose AMD graphics cards at a much higher rate than Intel CPU builders. 55% of machines with an AMD CPU also had an AMD GPU; whereas, only 19% of builds with an Intel CPU included an AMD GPU. In the last six months, AMD has started to lose even more ground to Intel and to Nvidia. On the CPU builds, only 10% of gamers building on PCPartPicker were opting to buy an AMD CPU. Among these, the percentage that decided to pair their AMD CPU with an AMD GPU dropped to 51%. The challenges that AMD is seeing in the overall GPU market are being felt even amongst their loyal supporters.

MojoKid writes from a report via HotHardware: AMD has just officially unveiled that desktop variants of its Zen processor family will now be branded RYZEN. Zen-based processors will eventually target desktops, servers, and mobiles device, but the first wave of products will be targeted at the performance desktop market, where gamers and VR continue to spur growth. AMD is positioning RYZEN as a high-performance option and though there will be other core configurations as well, AMD has disclosed that one of the high-end options in the initial RYZEN line-up will feature 8 cores (16 threads with SMT) and at minimum a 3.4 GHz base clock, with higher turbo frequencies. That processor will also be outfitted with 20MB of cache -- 4MB of L2 and 16MB of L3 -- and it will be infused with what AMD is calling SenseMI technology. SenseMI is essentially fancy branding for the updated branch predictor, prefetcher, and power and control logic in Zen. AMD's upcoming AM4 platform for RYZEN will be outfitted with all of the features expected of a modern PC enthusiast platform. AM4 motherboards will use DDR4 memory and feature PCIe Gen 3 connectivity, and support for USB 3.1 Gen 2, NVMe, and SATA Express. Performance demos of RYZEN shown to members of the press pit a stock Intel Core i7-6900K (3.2GHz base, 3.7GHz turbo) with Turbo Boost that was enabled on the 6900K, versus RYZEN with boost disabled running at 3.4GHz flat. In the demo, the RYZEN system outpaced the Core i7-6900K by a few seconds.

Reader MojoKid writes: AMD is announcing a new series of Radeon-branded products today, targeted at machine intelligence and deep learning enterprise applications, called Radeon Instinct. As its name suggests, the new Radeon Instinct line of products are comprised of GPU-based solutions for deep learning, inference and training. The new GPUs are also complemented by a free, open-source library and framework for GPU accelerators, dubbed MIOpen. MIOpen is architected for high-performance machine intelligence applications and is optimized for the deep learning frameworks in AMD's ROCm software suite. The first products in the lineup consist of the Radeon Instinct MI6, the MI8, and the MI25. The 150W Radeon Instinct MI6 accelerator is powered by a Polaris-based GPU, packs 16GB of memory (224GB/s peak bandwidth), and will offer up to 5.7 TFLOPS of peak FP16 performance. Next up in the stack is the Fiji-based Radeon Instinct MI8. Like the Radeon R9 Nano, the Radeon Instinct MI8 features 4GB of High-Bandwidth Memory (HBM) with peak bandwidth of 512GB/s. The MI8 will offer up to 8.2 TFLOPS of peak FP16 compute performance, with a board power that typical falls below 175W. The Radeon Instinct MI25 accelerator will leverage AMD's next-generation Vega GPU architecture and has a board power of approximately 300W. All of the Radeon Instinct accelerators are passively cooled but when installed into a server chassis you can bet there will be plenty of air flow. Like the recently released Radeon Pro WX series of professional graphics cards for workstations, Radeon Instinct accelerators will be built by AMD. All of the Radeon Instinct cards will also support AMD MultiGPU (MxGPU) hardware virtualization technology.

"As expected, today, December 11, 2016, Linus Torvalds unleashed the final release of the highly anticipated Linux 4.9 kernel," reports Softpedia. prisoninmate shares their article: Linux kernel 4.9 entered development in mid-October, on the 15th, when Linus Torvalds decided to cut the merge window short by a day just to keep people on their toes, but also to prevent them from sending last-minute pull requests that might cause issues like it happened with the release of Linux kernel 4.8, which landed just two weeks before first RC of Linux 4.9 hit the streets... There are many great new features implemented in Linux kernel 4.9, but by far the most exciting one is the experimental support for older AMD Radeon graphics cards from the Southern Islands/GCN 1.0 family, which was injected to the open-source AMDGPU graphics driver...

There are also various interesting improvements for modern AMD Radeon GPUs, such as virtual display support and better reset support, both of which are implemented in the AMDGPU driver. For Intel GPU users, there's DMA-BUF implicit fencing, and some Intel Atom processors got a P-State performance boost. Intel Skylake improvements are also present in Linux kernel 4.9.
There's also dynamic thread-tracing, according to Linux Today. (And hopefully they fixed the "buggy crap" that made it into Linux 4.8.) LWN.net calls this "by far the busiest cycle in the history of the kernel project."

An anonymous reader writes from a report via BleepingComputer: The security protocol that governs how virtual machines share data on a host system powered by AMD Zen processors has been found to be insecure, at least in theory, according to two German researchers. The technology, called Secure Encrypted Virtualization (SEV), is designed to encrypt parts of the memory shared by different virtual machines on cloud servers. AMD, who plans to ship SEV with its upcoming line of Zen processors, has published the technical documentation for the SEV technology this past April. The German researchers have analyzed the design of SEV, using this public documentation, and said they managed to identify three attack channels, which work, at least in theory.

[In a technical paper released over the past weekend, the researchers described their attacks:] "We show how a malicious hypervisor can force the guest to perform arbitrary read and write operations on protected memory. We describe how to completely disable any SEV memory protection configured by the tenant. We implement a replay attack that uses captured login data to gain access to the target system by solely exploiting resource management features of a hypervisor." AMD is scheduled to ship SEV with the Zen processor line in the first quarter of 2017.

Advanced Micro Devices, or AMD is launching an update for its Radeon graphics drivers that will help PC gamers enjoy more power-efficient gameplay during the holiday season. Radeon Software Crimson ReLive Edition offers high-performance gaming and better stability for consumers, professionals, and developers. From a report on VentureBeat: The new edition enables power-efficient gameplay with Radeon Chill and seamless in-game screen capture and streaming with Radeon ReLive. For designers, content creators, and game developers, Radeon Pro Software Crimson ReLive Edition delivers productivity and stability with up to 30 percent performance improvements in key applications. With Radeon ReLive, gamers can "relive" their gameplay by capturing, streaming, and sharing recorded gaming sessions. Highly efficient with minimal impact to gameplay, Radeon ReLive enables seamless playback of ReLive recordings via an easily accessible in-game toolbar, and offers quick and convenient customizable settings, custom scene layouts, and more, AMD said. With Radeon ReLive, gamers now have a way to capture gaming highlights, and share their gaming exploits and conquests with online friends and competitors -- all integrated within Radeon Software.

Jeremy Hellstrom, writing for PC Perspective (edited):Compared to Q2 2016, total GPU shipments including discrete and integral chips in the mobile and desktop markets increased by 20%; good but not enough to recover from the volume we saw in Q3 2015. Individually, total AMD sales increased by 15%, and Intel saw 18% boost, but it was NVIDIA that was the most successful with an impressive 39% increase. In AMD's case, it saw sales of its aging desktop APUs drop by 10% but that was quickly offset by a jump in discrete GPU sales of 34.7% and an increase in laptop demand by 19.1%. The discrete GPU market as a whole has grown by 35.6% compared to the last quarter and by 10.1% when compared to last year. This is not bad news for AMD or Intel but it is certainly NVIDIA which has the most to celebrate.

Google Cloud will add GPUs as a service early next year, the company has said. Amazon Web Services, Microsoft Azure and IBM's Bluemix all already offer GPU as a service. From a report on GeekWire: Google may be seeking to distinguish itself, however, with the variety of GPUs it's offering. They include the AMD FirePro S9300 x2 and two offerings from NVIDIA Tesla: the P100 and the K80. And Google will charge by the minute, not by the hour, making GPU usage more affordable for customers needing it only for short periods. CPU-based machines in the cloud are good for general-purpose computing, but certain tasks such as rendering or large-scale simulations are much faster on specialized processors, Google explained. GPUs contain hundreds of times as many computational cores as CPUs and excel at performing risk analysis, studying molecular binding or optimizing the shape of a turbine blade. Google's GPU services will be available in early 2017 through Google Compute Engine and Google Cloud Machine Learning.

Whereas Apple's new 13-inch MacBook Pros feature integrated Iris Pro graphics, the 15-inch MacBook Pros feature dedicated AMD graphics, resulting in significant performance improvements over previous MacBook Pro models. Ars Technica's Andrew Cunningham found the Radeon Pro 455 graphics chip in particular to be a "significant boost" over the dedicated GPUs available in the 2012-2015 MacBook Pro models, such as the Nvidia GeForce GTX 650M, Nvidia GeForce GTX 750M, and AMD Radeon R9 M370X. MacRumors reports: AMD's Polaris-based Radeon Pro 450, Radeon Pro 455, and built-to-order Radeon Pro 460 GPUs in the new 15-inch MacBook Pro support up to six displays, whereas Intel's integrated GPUs affixed to the logic board can drive a total of three displays. The expanded support enables the new MacBook Pro to drive two of Apple and LG's new UltraFine 5K displays at 60Hz simultaneously. Intel's GPUs can't because, due to bandwidth limitations of the DisplayPort 1.2 spec, the two 5K displays technically function as four displays. This method is known as Multi-Stream Transport (MST). Apple could have used Nvidia's faster Pascal-based GPUs, which support DisplayPort 1.3, but Thunderbolt 3 and most monitors do not support the higher-bandwidth spec yet. In the meantime, Nvidia's GPUs can only drive up to three displays beyond the main MacBook Pro screen -- not enough for dual 5K displays over MST. Apple officially says the 15-inch MacBook Pro offers up to 130% faster graphics performance, and up to 2.5x more computing power per watt, compared to the previous-generation 15-inch MacBook Pro, but those stats are based on the built-to-order Radeon Pro 460 chip that costs between $100 and $200 extra.

At an event on Thursday, Apple unveiled the new 2016 MacBook Pro. The redesigned MacBook Pro comes with "incredible extreme" all-metal body. The main attraction of the new MacBook Pro is an OLED touch strip at the top that Apple is calling the Touch Bar. The Touch Bar comes with a fingerprint scanner Touch ID that users can tap to log-in quickly to their computer as well as make online payments. The touch strip offers on-screen button that changes according to the application you're running. Schiller, Apple SVP, said it was time Apple gotten rid of the dedicated function keys. The new MacBook Pro is thinner and lighter than the existing model, and it is powerful too. It comes in two screen sizes: 13-inch, which weighs 3 pounds and measures 14.9mm -- down from 18mm from older MacBook Pro. The trackpad is larger too, Apple says, twice as larger than the older one. Also, it's Force Touch trackpad. ArsTechnica adds: Both laptops are still recognizably MacBook Pros, but in keeping with Apple's design priorities they've got slimmer profiles and smaller footprints. This is made possible in part by the move to USB Type-C ports like the one in the MacBook, all four of which support Thunderbolt 3. All four ports can be used to charge the system, too. Compared to the measly one port in the MacBook, the MacBook Pros are much more appealing to people who plug lots of stuff into their computers at once. Apple has also made the cowardly decision to retain the headset jack. Both systems include new Intel Skylake processors -- dual-core chips in the 13-inch Pro and quad-core chips in the 15-inch model, just like before. The 13-inch Pros ship exclusively with Intel Iris 540 GPUs, while the 15-inch models ship with Polaris-based AMD Radeon graphics at the high-end.The 13-inch model MacBook Pro starts at $1,799, whereas the 15-inch model starts at $2,399.

It's been 18 months since the original Mintbox Mini launched, and this week saw the release of the new Mintbox Mini Pro (which costs just $100 more). BrianFagioli quotes BetaNews: That extra money gets you a faster processor, more powerful graphics, double the storage, twice the RAM, improved Wi-Fi, Bluetooth, and an additional Ethernet port... This diminutive desktop is the same size as the previously-released Mintbox... Thankfully, it retains the same cute appearance and Linux Mint branding.
Their article calls it a "beautiful little computer that comes pre-loaded with Linux Mint 18 Cinnamon (64-bit)," and the Linux Mint blog promises this fanless device offers "better passive cooling thanks to an all-metal black housing" -- and comes with six different USB ports.

You asked, he answered!

Raspberry Pi founder and CEO Eben Upton has responded to questions submitted by Slashdot readers. Read on for his answers.

Sony's PlayStation 4, which will go on sales in two months, comes loaded with rendering pipeline and some proprietary upscaling techniques that can improve lower resolution base signals to take fuller advantage of a 4K display. Microsoft is seemingly upset with how Sony is marketing this, and it is not shying from telling people that no amount of upscaling can fill in those missing 4K pixels and the hardware inefficiency to produce native and "true 4K" images that the Project Scorpio, its gaming console that is coming next year can. Microsoft has also said that any game that it will launch during the Scorpio timeframe will "natively render at 4K." But the debate is anything from over because Microsoft keeps reminding everyone that the processor and GPU in its upcoming console is more powerful. As ArsTechnica explains: With Scorpio, Microsoft seems to be arguing that every first-party game at launch will be able to generate and render nearly 8.3 million pixels (four times as many as a 1080p game) at an acceptable frame rate (i.e., at least 30 times a second). That would be quite an achievement. As we noted back at E3, it currently takes pricey, high-end PC graphics cards like the Nvidia GTX 1080 or the AMD R9 Fury X -- cards that run $300 or much higher -- to "barely scrape by" with a native 4K, 30fps game. And those PC cards seem to have significantly more raw power than what is being claimed by Microsoft -- 9 and 8.4 teraflops, respectively, vs. a claimed 6 teraflops for Scorpio (and 4.2 teraflops for the PS4 Pro).Microsoft's head of Xbox planning, Albert Penello said, "I know that 4.2 teraflops is not enough to do true 4K." In an interview with Eurogamer, Penello adds:I think there are a lot of caveats they're giving customers right now around 4K. They're talking about checkerboard rendering and up-scaling and things like that. There are just a lot of asterisks in their marketing around 4K, which is interesting because when we thought about what spec we wanted for Scorpio, we were very clear we wanted developers to take their Xbox One engines and render them in native, true 4K. That was why we picked the number, that's why we have the memory bandwidth we have, that's why we have the teraflops we have, because it's what we heard from game developers was required to achieve native 4K.

MojoKid writes: There was quite a stir caused recently when it was determined that Microsoft would only be fully supporting Intel's Kaby Lake and AMD's Zen next-generation processor microarchitectures with Windows 10. It's easy to dismiss the decision as pure marketing move, but there's more to consider and a distinction to be made between support and compatibility. The decision means future updates and optimizations that take advantage of the latest architectural enhancements in these new processors won't be made for older OS versions. Both of these microarchitectures have new features that require significant updates to Windows 10 to optimally function. Kaby Lake has updates to Intel's Speed Shift technology that make it possible to change power states more quickly than Skylake, for example. Then there's Intel's Turbo Boost 3.0, which is only baked natively into Windows 10 Redstone 1. For an operating system to optimally support AMD's Zen-based processors, major updates are likely necessary as well. Zen has fine-grained clock gating with multi-level regions throughout the chip, in addition to newer Simultaneous Multi-Threading technology for AMD chips. To properly leverage the tech in Zen, Microsoft will likely have to make updates to the Windows kernel and system scheduler, which is more involved than a driver update. Of course, older versions of Windows and alternative operating systems will still install and run on Kaby Lake and Zen. They are x86 processors, after all.

An anonymous reader writes: Buried in the announcement of the new Kaby Lake (seventh-generation) processors and a rash of incoming notebooks set to use them is the confirmation that they will have a Windows 10 future. Microsoft has been warning people for ages that Kaby Lake will not run on anything older than Windows 10, and it looks like AMD's upcoming Zen chip will be going the same way. Microsoft said, "As new silicon generations are introduced, they will require the latest Windows platform at that time for support. This enables us to focus on deep integration between Windows and the silicon, while maintaining maximum reliability and compatibility with previous generations of platform and silicon." "We are committed to working with Microsoft and our ecosystem partners to help ensure a smooth transition given these changes to Microsoft's Windows support policy," an Intel spokesperson said. "No, Intel will not be updating Win 7/8 drivers for 7th Gen Intel Core [Kaby Lake] per Microsoft's support policy change." An AMD representative was equally neutral. "AMD's processor roadmap is fully aligned with Microsoft's software strategy," AMD chief technical officer Mark Papermaster said, via a company spokeswoman. Slashdot reader MojoKid via HotHardware has some more details on Intel's Kaby Lake 7th Gen Core Series Processors for those yearning to learn more.

An anonymous reader writes from a report via Ars Technica: HP has announced today two new desktop PCs: HP Elite Slice and Pavilion Wave. The HP Elite Slice is a modular machine, with USB Type-C for power and I/O. The base unit contains all the core guts of the PC -- up to a 35W Core i7-6700T processor, up to 32GB of RAM, up to 512GB NVMe storage, gigabit Ethernet, 802.11ac Wi-Fi and several ports. The top cover of the main unit is modular, while the bottom of the unit contains a special connector that can allow for additional modules to be stacked. HP has an audio module that includes speakers and a microphone array, and an optical drive module. It should be available later this month, starting at $699. The Pavilion Wave on the other hand combines a PC and a speaker in a 10.3 inch tall triangular box. As for specs, it features a 35W processor, up to an i7 processor, up to 16GB RAM, with up to 1TB SSD or 2TB HDD. An AMD R9 M470 is optional. In addition to the speaker, the Wave features a microphone array for Cortana support.

Reader MojoKid writes: Intel is readying a new family of processors, based on its next-gen Kaby Lake microarchitecture, that will be the foundation of the company's upcoming 7th Generation Core processors. Although Kaby Lake marks a departure from Intel's "tick-tock" release cadence, there have been some tweaks made to its 14nm manufacturing process (called 14nm+) that have resulted in significant gains in performance, based on clock speed boosts and other optimizations. In addition, Intel has incorporated a new multimedia engine into Kaby Lake that adds hardware acceleration for 4K HEVC 10-bit transcoding and VP9 decoding. Skylake could handle 1080p HEVC transcoding, but it didn't accelerate 4K HEVC 10-bit transcoding or VP9 decode and had to assist with CPU resources. The new multimedia engine gives Kaby Lake the ability to handle up to eight 4Kp30 streams and it can decode HEVC 4Kp60 real-time content at up to 120Mbps. The engine can also now offload 4Kp30 real-time encoding in a dedicated fixed-function engine. Finally, Intel has made some improvements to their Speed Shift technology, which now takes the processor out of low power states to maximum frequency in 15 milliseconds. Clock speed boosts across Core i and Core m 7th gen series processors of 400-500 MHz, in combination with Speed Shift optimizations, result in what Intel claims are 12-9 percent performance gains in the same power envelope as its previous generation Skylake series, and even more power efficient video processing performance.

Reader MojoKid writes: AMD has been talking about the claimed 40% IPC (Instructions Per Clock) improvement of its forthcoming Zen processor versus the company's existing Excavator core for ages. Zen's initial availability is slated for late this year, with lager-scale roll-out planned for early 2017. However, last night, at a private press event in San Francisco, AMD unveiled a lot more details on their Zen processor architecture. AMD claims to have achieved that 40 percent IPC uplift with a newly-designed, higher-performance branch prediction and a micro-op cache for more efficient issuing of operations. The instruction schedule windows have been increased by 75% and issue-width and execution resources have been increased by 50%. The end result of these changes is higher single-threaded performance, through better instruction level parallelism. Zen's pre-fetcher is also vastly improved. There is 8MB of shared L3 cache on board now, a unified L2 cache for both instruction and data, and separate, low-latency L1 instruction and data caches. The new archicture offers up to 5x the cache bandwidth to the cores versus previous-gen offerings. However, after all the specsmanship was out of the way, AMD actually showcased a benchmark run of an 8-core Zen Summit Ridge procesor versus Intel's Broadwell-E 8-core chip, both running at 3GHz and processing a Blender rending workload. In the demo, the 8-core Zen CPU actually outpaced Intel's chip by a hair. Blender may have been chosen for a reason but this early benchmark demo looks impressive for AMD and its forthcoming Zen architecture.

Marius Nestor, writing for Softpedia: After a few weeks from its official release, it finally happened, Linux kernel 4.7 has just landed in the stable software repositories of the popular, lightweight and highly customizable Arch Linux operating system. Linux kernel 4.7 is the most stable and advanced kernel branch, and only a few GNU/Linux distributions have adopted since its launch on July 24, 2016. It's still marked as "mainline" not "stable" or "longterm" on the kernel.org website, which means that it didn't receive a maintenance update at the moment of writing this article. As for its new features, Linux kernel 4.7 comes with an updated AMDGPU graphics driver with support for AMD Radeon RX 480 GPUs, LoadPin, a brand new security module that ensures all modules loaded by the kernel originate from the same filesystem, and support for upgrading firmware using the EFI "Capsule" mechanism. Linux kernel 4.7 also marks the sync_file fencing mechanism used in the Android mobile operating system as stable and ready for production, implements support for generating virtual USB Device Controllers in USB/IP, supports parallel directory lookups, and introduces the "schedutil" frequency governor, which is faster and more accurate than the current ones.
