Intel to Accelerate Basin Falls Unveil, Coffee Lake Launch

According to DigiTimes, sources among Taiwan-based PC vendors have indicated that Intel's upcoming Basin Falls platform, which includes Skylake-X and Kaby Lake-X processors on a new X299 chipset, will be unveiled at Computex 2017 (May 30th, June 3rd), in Taipei - two months earlier than expected. This move comes accompanied by an accelerated launch of the Coffee Lake microarchitecture, which still uses the 14 nm process, to August 2017 from an initial January 2018 launch. If true, this is big in a number of ways - that Intel would bring forward a product launch 4 months has some interesting implications - or at least, confirmations.

Remember that Coffee Lake is supposed to carry an increased number of cores in its mainstream designs. And we all know how Intel's line-up has almost been torn apart by Ryzen's aggressive core and thread-count, with AMD offering more cores and threads than Intel at virtually all price-points. And even if an argument is made regarding Intel's better gaming performance, that's one scenario out of many. Future proofing, professional work, multimedia, all of these assert AMD's dominance in a pure price-performance ratio. I, for one, would gladly give up some FPS in some games and accept an increased number of cores than go the other way around (especially with AMD's platform support and the number of patches that have increased game performance on Ryzen CPUs.)

AMD Ryzen Machine Crashes to a Sequence of FMA3 Instructions

An AMD Ryzen 7-1800X powered machine was found to be crashing upon execution of a very specific set of FMA3 instructions by Flops version 2, a simple open-source CPU benchmark by Alexander "Mystical" Yee. An important point to note here is that this little known benchmark has been tailored by its developer to be highly specific to the CPU micro-architecture, with separate binaries for each major x64 architecture (eg: Bulldozer, Sandy Bridge, Haswell, Skylake, etc.), and as such the GitHub repository does not have a "Zen" specific binary.

Members of the HWBot forums found that Ryzen powered machines crash on running the Haswell-specific binary, at "Single-Precision - 128-bit FMA3 - Fused Multiply Add." The Haswell-specific binary (along with, we imagine, Skylake), adds support for the FMA3 instruction-set, which Ryzen supports, and which lends some importance to the discovery of this bug. What also makes this important is because a simple application, running at user privileges (i.e. lacking special super-user/admin privileges), has the ability to crash the machine. Such a code could even be executed through virtual machines, and poses a security issue, with implications for AMD's upcoming "Naples" enterprise processor launch.

AMD Talks Zen 3, "Raven Ridge," and More at Reddit AMA

AMD, at its post-Ryzen 7 launch Reddit AMA, disclosed some juicy details about its other upcoming socket AM4 chips, beginning with the rest of the Ryzen 5 and Ryzen 3 "Summit Ridge" processor roll-out, and a little bit about its 8th generation socket AM4 APU, codenamed "Raven Ridge." To begin with, AMD CEO Lisa Su stated that "Raven Ridge" will also be sold under the Ryzen brand. This would mark a departure from the less-than-stellar A-series branding for its performance APUs. "Raven Ridge" likely combines a "Zen" quad-core CPU complex (CCX) with an integrated GPU based on one of AMD's newer GPU architectures (either "Polaris" or "Vega").

The range-topping Ryzen 7 series will lead the company's lineup throughout Q1, with six-core and quad-core Ryzen 5 and Ryzen 3 series launches being scheduled for later this year. Our older reports pinned Ryzen 5 series rollout for Q2, and Ryzen 3 series for the second half of 2017. This is likely also when the company rolls out "Raven Ridge" initially as mobile Ryzen products (BGA packages, which will likely also be used in AIOs), and later as desktop socket AM4 parts.

AMD's Upcoming Ryzen Line-up Could Feature 6-Core Chips After All

It's always a dance between rumours, expectations and "theorycrafting" when it comes to the launch of any particularly exciting product. And with AMD's Ryzen chips currently being the most hotly anticipated development (and product launch) in the hardware world, well, let's just say that anticipation is really building up to enormous levels, with any possible details surrounding AMD's line-up being the cause, in some cases, of heated debate.

Case in point: with AMD's CCX (CPU Complex) being indivisible, this would mean a blow not only to budget-conscious consumers, but also to AMD's ability to engender its product line. Flexibility has always been the name of the game with AMD (discounting their CMT-based Bulldozer and derived architectures), with the company offering triple-core processors in the past (and weren't those the good old days of processor unlocking). However, now reports have come in that Ryzen's CCX are actually divisible, which could open up possibilities for some theoretically value-breaking hexa-core Ryzen chips.

AMD Says "ZEN" CPU Architecture is Expected to Last 4 Years

After spending almost 4 years developing and perfecting (as much as can be perfected in such an amount of time) it's ZEN CPU architecture, AMD is looking to extract some mileage out of it. Mark Papermaster, AMD's chief technology officer, confirmed the four-year lifespan in a conversation with PC World at CES 2017 in Las Vegas, though he declined to discuss specifics. When asked how long ZEN would last (especially comparing to Intel's now-failing two-year tick-tock cadence, Papermaster confirmed the four-year lifespan: "We're not going tick-tock," he said. "ZEN is going to be tock, tock, tock."

AMD Details ZEN Microarchitecture IPC Gains

AMD Tuesday hosted a ZEN microarchitecture deep-dive presentation in the backdrop of Hot Chips, outlining its road to a massive 40 percent gain in IPC (translated roughly as per-core performance gains), over the current "Excavator" microarchitecture. The company credits the gains to three major changes with ZEN: better core engine, better cache system, and lower power. With ZEN, AMD pulled back from its "Bulldozer" approach to cores, in which two cores share certain number-crunching components to form "modules," and back to a self-sufficient core design.

Beyond cores, the next-level subunit of the ZEN architecture is the CPU-Complex (CCX), in which four cores share an 8 MB L3 cache. This isn't different from current Intel architectures, the cores share nothing beyond L3 cache, making them truly independent. What makes ZEN a better core, besides its independence from other cores, and additional integer pipelines; subtle upscaling in key ancillaries such as micro-Op dispatch, instruction schedulers; retire, load, and store queues; and a larger quad-issue FPU.

AMD ZEN Quad-Core Subunit Named CPU-Complex (CCX)

We've been chasing AMD Zen for a long time now. Our older report from April 2015 uncovered an important detail about component organization on Zen processors - the clumping of four CPU cores into a highly-specialized, possibly indivisible subunit referred to then, as the "Zen Quad-core Unit." Some of the latest presentations about the architecture, following AMD's "performance reveal" event from earlier this month, shed more light on this quad-core unit.

AMD is referring to the Zen quad-core unit as the CPU-Complex (CCX). Each CCX is a combination of four independent CPU cores. Unlike on "Bulldozer," a "Zen" core does not share any of its number-crunching machinery with neighboring cores. Each "Zen" core has a dedicated L2 cache of 512 KB, and four Zen cores share an 8 MB L3 cache. AMD will control core-counts by controlling CCX units. A "Summit Ridge" socket AM4 processor features two CCX units (making up eight cores in all), sharing a dual-channel DDR4 memory controller, and the platform core-logic (chipset), complete with an integrated PCI-Express root complex. Socket AM4 APUs will feature one CCX unit, and an integrated GPU in place of the second CCX. With this, AMD is able to bring the two diverse desktop platforms under one socket.

AMD Dragged to Court over Core Count on "Bulldozer"

This had to happen eventually. AMD has been dragged to court over misrepresentation of its CPU core count in its "Bulldozer" architecture. Tony Dickey, representing himself in the U.S. District Court for the Northern District of California, accused AMD of falsely advertising the core count in its latest CPUs, and contended that because of they way they're physically structured, AMD's 8-core "Bulldozer" chips really only have four cores.

The lawsuit alleges that Bulldozer processors were designed by stripping away components from two cores and combining what was left to make a single "module." In doing so, however, the cores no longer work independently. Due to this, AMD Bulldozer cannot perform eight instructions simultaneously and independently as claimed, or the way a true 8-core CPU would. Dickey is suing for damages, including statutory and punitive damages, litigation expenses, pre- and post-judgment interest, as well as other injunctive and declaratory relief as is deemed reasonable.

AMD "Zen" CPU Prototypes Tested, "Meet all Expectations"

AMD reportedly finished testing some of its first "Zen" micro-architecture CPU prototypes, and concluded that they "meet all expectations," with "no significant bottlenecks found" in its design. This should mean that AMD's "Zen" chips should be as competitive with Intel chips as it set them out to be. The company is planning to launch its first client CPUs based on the "Zen" micro-architecture in 2016, based on its swanky new AM4 socket, with DDR4 memory and integrated PCIe (a la APUs). Zen sees AMD revert to the large, monolithic core design, from its "Bulldozer" multi-core module design with a near doubling of number-crunching machinery per-core, compared to its preceding architecture.

AMD Zen Features Double the Per-core Number Crunching Machinery to Predecessor

AMD "Zen" CPU micro-architecture has a design focus on significantly increasing per-core performance, particularly per-core number-crunching performance, according to a 3DCenter.org report. It sees a near doubling of the number of decoder, ALU, and floating-point units per-core, compared to its predecessor. In essence, the a Zen core is AMD's idea of "what if a Steamroller module of two cores was just one big core, and supported SMT instead."

In the micro-architectures following "Bulldozer," which debuted with the company's first FX-series socket AM3+ processors, and running up to "Excavator," which will debut with the company's "Carrizo" APUs, AMD's approach to CPU cores involved modules, which packed two physical cores, with a combination of dedicated and shared resources between them. It was intended to take Intel's Core 2 idea of combining two cores into an indivisible unit further.

AMD to Emphasize on "Generation" with Future CPU Branding

AMD is planning to play a neat branding game with Intel. Branding of the company's 2016 lineup of CPUs and APUs will emphasize on "generation," much in the same way Intel does with its Core processor family. AMD will mention in its PIB product packaging, OEM specs sheets, and even its product logo (down to the case-badge), that its 2016 products (FX-series CPUs and A-series APUs) are the company's "6th generation." 2016 marks prevalence of Intel's Core "Skylake" processor family, which is its 6th generation Core family (succeeding Nehalem/Westmere, Sandy Bridge, Ivy Bridge, Haswell, and Broadwell). AMD is arriving at its "6th generation" moniker counting "Stars," "Bulldozer," "Piledriver," "Steamroller," and "Excavator," driving its past 5 generations of APUs, and the occasional FX CPU.

It turns out that the emphasis on "generation" is big with DIY and SI retail channels. Retailers we spoke with, say that they find it easier to break through Intel's often-confusing CPU socket change cycle, which ticks roughly every 18-24 months. Customers, they say, find it easier to simply mention the "generation" of Core processor they want, to get all relevant components to go with them (such as motherboard and memory bundles). While AMD's FX brand clearly didn't see generations beyond "Piledriver," the company's decision to unify the socket for its FX and A-Series product lines next year, with AM4, makes "6th generation FX processor" valid.

First AMD "Zen" Chips to be Quad-Core

Some of the first CPUs and APUs based on AMD's next-generation "Zen" micro-architecture could be quad-core. "Zen" will be AMD's first monolithic core design after a stint with multi-core modules, with its "Bulldozer" architecture. Our older article details what sets Zen apart from its predecessor. As expected, in a multi-core chip, Zen cores share no hardware resources with each other, than a last-level cache (L3 cache), much like Intel's current CPU architecture.

There's just one area where Zen will differ from Haswell. With Haswell, Intel has shown that it can clump any number of cores on a chip, and make them share a proportionately large L3 cache. Haswell-E features 8 cores sharing a 20 MB cache. The Haswell-EX features 18 cores sharing 45 MB of cache. With Zen, however, the scale up stops at 4 cores sharing 8 MB of L3 cache. A set of four cores makes up what AMD calls a "quad-core unit." To be absolutely clear, this is not a module, the cores share no hardware components with each other, besides the L3 cache.

AMD "Zen" CPU Core Block Diagram Surfaces

As a quick follow up to our older report on AMD's upcoming "Zen" CPU core micro-architecture being a reversion to the monolithic core design, and a departure from its "Bulldozer" multicore module design which isn't exactly flying off the shelves, a leaked company slide provides us the first glimpse into the core design. Zen looks a lot like "Stars," the core design AMD launched with its Phenom series, except it has a lot more muscle, and one could see significant IPC improvements over the current architecture.

To begin with, Zen features monolithic fetch and decode units. On Bulldozer, two cores inside a module featured dedicated decode and integer units with shared floating-point units. On Zen, there's a monolithic decode unit, and single integer and floating points. The integer unit has 6 pipelines, compared to 4 per core on Bulldozer. The floating point unit has two large 256-bit FMAC (fused-multiply accumulate) units, compared to two 128-bit ones on Bulldozer. The core has a dedicated 512 KB L2 cache. This may be much smaller than the 2 MB per module on Bulldozer, but also indicate that the core is able to push through things fast enough to not need cushioning by a cache (much like Intel's Haswell architecture featuring just 256 KB per core). In a typical multi-core Zen chip, the cores will converge at a large last-level cache, which routes data between them to the processor's uncore, which will feature a DDR4 IMC and a PCI-Express 3.0 root complex.

AMD "Zen" A Monolithic Core Design

AMD's upcoming "Zen" architecture will see a major change in the way the company designs its CPU cores. It will be a departure from the "module" core design introduced with "Bulldozer," in which two cores with shared resources constitute the indivisible unit of a multi-core processor. A "Zen" core will have dedicated resources in a way things used to be before "Bulldozer," and only the last-level cache (L3 cache), will be shared between cores. "Zen" will also implement SMT, much in the same way as Intel processors do, with HyperThreading Technology.

The first implementation of "Zen" will be an insanely powerful APU (on paper anyway), featuring 16 physical "Zen" CPU cores, 32 logical CPUs enabled with SMT, 512 KB dedicated L2 cache per core, and 32 MB of shared L3 cache. The CPU's ISA instruction set will see a spring-cleaning, with the removal of underused instruction-sets, and the introduction of new ones. Other features on this APU are equally surprising - a quad-channel DDR4 integrated memory controller, a separate HBM (high-bandwidth memory) controller dedicated to the integrated graphics, with up to 512 GB/s bandwidth, and an integrated graphics core featuring "Greenland-class" stream processors. Given that AMD is able to build 7-billion transistor GPUs on existing 28 nm processes, building an APU with these chops doesn't sound far-fetched. The company could still have to rely on a newer fab.

AMD to Switch to GlobalFoundries' 28 nm SHP Node in 2015

Faced with continuous development roadblocks with TSMC, AMD is reportedly planning to switch to the 28 nm SHP process of GlobalFoundries, to build GPUs in 2015. The 28 nm SHP (super high-performance) node will allow the company to lower voltages, giving it greater room to increase clock speeds of its upcoming GPUs. AMD's GPUs in 2015 could be based on its latest Graphics CoreNext 1.2 architecture, and AMD needs every means to minimize voltages, and crank up clock speeds.

The company hasn't abandoned TSMC completely just yet, with reports speaking of AMD using the Taiwanese fab's 16 nm FinFet node to manufacture its next-generation "Zen" CPUs. Zen is the successor to AMD's "Bulldozer" architecture and its derivatives ("Piledriver" and "Steamroller.") It could feature a radically different core design.

SHARKOON Releases the Bulldozer Midi-Tower PC Case

SHARKOON Technologies has now made available the Bulldozer, a midi-tower PC chassis for gamers and enthusiasts that are on a tighter budget. This new case measures 480 (L) x 235 (W) x 460 (H) mm, it weighs 6.5 kg and features a front I/O panel with two USB 3.0 and two USB 2.0 ports, two 5.25-inch drive bays, and seven (4 x 2.5-inch and 3 x 3.5-inch) internal drive trays.

SHARKOON's case also has an acrylic side window, two (red, blue or green-colored) 120 mm fans (front and back), and it offers support for graphics cards up to 415 mm long. The Bulldozer comes in three color schemes (black/red, black/blue, black/green) and costs 49.99 Euro.

Engineering Sample Of AMD Steamroller Based APU Spotted

Hardware news site WCCF Tech spotted an interesting entry listed in the Bionic research database. The ES (Engineering Sample) chip could be a part of AMD's next-generation APU series featuring the new and improved Steamroller core. While we don't expect performance to increase by leaps and bounds, but Steamroller builds on the Bulldozer architecture and has a target to offer as much as a 30% improvement in performance over the original core.
The ES code 2M186092H4467_23/18/12/05_1304 tells us even more. According to earlier observations (here and here), the four numbers in the middle part tell a bit about clock speeds. If the first one is not 00 (no turbo, see Kabini ES), it indicates a turbo clock of 2.3GHz. The "18? stands for 1.8GHz nominal frequency. I'm not so sure about the "12?. It could stand for 1.2Ghz North Bridge clock. Finally the "05? indicates a 500MHz GPU clock. The right part "1304? is the GPU code, which - thanks to earlier revelations - can be identified as AMD1304.1 = "KV SPECTRE MOBILE 35W (1304)".
A 2.3 GHz Turbo core is pretty low, which can be attributed to the early state of the Engineering Sample. Hopefully clock speeds hit further north of just 1.8 GHz CPU and 500 MHz graphics, especially for the 35W part. The next-generation chips will be manufactured on the new bulk 28nm manufacturing process at Global Foundries.Source: WCCF Tech

AMD Super Pi History To Be Rewritten, Courtesy The Stilt

AMD Super Pi History To Be Rewritten, Courtesy Of The Stilt

AMD's typically underwhelming Super PI performance, that was usually attributed to architectural limitations when it comes to the X87 instruction set, appears to have been nothing more than a blunder on the part of the developers responsible with BIOS development and optimization for AMD platforms. Finnish overclocker, The Stilt, figured out how to considerably improve performance by going through the BIOS developers guides. The exact same guides available to the BIOS R&D teams of motherboard vendors, a surprising fact considering a single man managed to outdo an entire industry. Here is the download link to the patch: click

The Stilt posted a video in which he showed a 4.1GHz A10-6800K completing SuperPI in 17 minutes and 34 seconds. The fastest 5GHz Richland SuperPI 32M is around 18 minutes and 15 seconds. A lot faster! For more information, check out the thread in the HWBot forums.

APUs Make Up Nearly 75% of AMD's Processor Sales

Despite losing in market share to Intel, AMD has reason to cheer as its APU gambit is beginning to pay off. According to the latest architecture- and core count-specific sales figures for AMD given out by Mercury Research detailing Q3-2013 in context of two preceding quarters, APUs make for nearly 75% of AMD's processor sales, and the company's recently-launched "Trinity" line of desktop and mobile APUs are off to a flying start.

The most popular chips in AMD's stable are its "Bobcat" Zacate series low-power APUs, which are being built into entry-level computing devices such as netbooks, nettops, and all-in-one desktops. The chips make up 39 percent of AMD's sales in Q3, followed by another APU line, the A-Series "Trinity", which is available in desktop and mobile variants, offers a combination of a fast integrated graphics processor with up to four CPU cores, and makes up 26.1 percent of AMD's sales. AMD's A-Series "Llano" can still be bought in the market, and makes up 7.4 percent of AMD's sales in Q3.

Latest HP ProLiant Gen8 Servers Integrate New AMD Opteron Processors

Today AMD announced 11 servers from its customers, including two based on the new HP ProLiant Gen8 platform, will be integrating previously unannounced versions of the award-winning high-performance AMD Opteron 6200 Series processor and the low-power AMD Opteron 4200 Series processor. These servers are based on five new AMD Opteron processors that offer increased performance without an increase in power consumption, providing customers more choice in using the world’s best price/performance x86 server processor.

Last month, HP launched two HP ProLiant Gen8 servers using the new AMD Opteron processors and plans to refresh the ProLiant DL585 G7 and the BL685c G7 later this year. Moreover, Dell is also expected to refresh its AMD offering with the latest AMD Opteron processors in the PowerEdge C6145, C6105, R415, R515, R715, R815 and the M915.

Trinity (Piledriver) Integer/FP Performance Higher Than Bulldozer, Clock-for-Clock

AMD's upcoming "Trinity" family of desktop and mobile accelerated processing units (APUs) will use up to four x86-64 cores based on the company's newest CPU architecture, codenamed "Piledriver". AMD conservatively estimated performance/clock improvements over current-generation "Bulldozer" architecture, with Piledriver. Citavia put next-generation A10-5800K, and A8-4500M "Trinity" desktop and notebook APUs, and pitted them against several currently-launched processors, from both AMD and Intel.

It found integer and floating-point performance increases clock-for-clock, against Bulldozer-based FX-8150. The benchmark is not multi-threaded, and hence gives us a fair idea of the per core performance. On a rather disturbing note, the performance-per-GHz figures of Piledriver are trailing far behind K12 architecture (Llano, A8-3850), let alone competitive architectures from Intel.

AMD 2012 CPU Roadmap Unveils FX-X300 and A10 Series

AMD is pushing on with a desktop product lineup that's leveraging its Piledriver CPU and Graphics CoreNext GPU architectures in 2012. Apparently, the company will have a faster product development cycle to catch up with Intel's "Tick-Tock", as revealed in a roadmap slide scored by DonanimHaber. The current product lineup will remain unchanged in the first quarter of 2012. Then in the second quarter, AMD will launch a few more socket AM3+ FX-8000, FX-6000, and FX-4000 series eight, six, and four-core processors; along with the much talked about "Trinity" accelerated processing unit.

The fastest "Trinity" APUs will get a new brand identifier, the A10-5000 series. These APUs will pack next-generation "Piledriver" modular cores and Radeon HD 7600D series graphics. Around this time, AMD will also launch the Brazos 2.0 low-power APU for netbooks, nettops, and embedded computing devices. Brazos 2.0 will get the E2-1000 series branding. The big change is reserved for the third quarter of 2012, when AMD launches the successor of its less-than-lucky AMD FX "Bulldozer" processor family.

AMD Reports Fourth Quarter and Annual Results

AMD (NYSE:AMD) today announced revenue for the fourth quarter of 2011 of $1.69 billion, net loss of $177 million, or $0.24 per share, and operating income of $71 million. The company reported non-GAAP net income of $138 million, or $0.19 per share, and non-GAAP operating income of $172 million. Fourth quarter non-GAAP net income excludes an impairment of AMD's investment in GLOBALFOUNDRIES of $209 million, restructuring charges of $98 million, the loss from discontinued operations of $4 million, the amortization of acquired intangible assets of $3 million and a loss on debt repurchase of $1 million.

For the year ended December 31, 2011, AMD reported revenue of $6.57 billion, net income of $491 million, or $0.66 per share, and operating income of $368 million. Full year non-GAAP net income was $374 million, or $0.50 per share, and non-GAAP operating income was $524 million.

AMD FX-8150 Tested with Latest Windows Hotfixes, Still No Improvement

German tech website TweakPC did a before-after comparison of applying Microsoft's recently-released KB2645594 + KB2646060 Windows updates, which intend to improve performance of systems running AMD FX processors, by improving the way in which the OS deals with Bulldozer cores, using a top-of-the-line FX-8150 processor. The reviewer put FX-8150 through synthetic tests such as AIDA64 (CPU benchmarks, FPU benchmarks), Cinebench 11.5, MaxxPi (multi-threaded PI calculations), WPrime, Twofish AES, 3DMark (Vantage and 11), ComputeMark; and some real-world tests such as WinRAR, Resident Evil 5, and Battleforge. Barring Resident Evil 5, where the patched FX-8150 produced 4% higher performance and WinRAR, where it produced 3% higher performance, there were no significant performance gains noticed. The review can be accessed at the source.
