Mark Papermaster, chief technology officer and executive vice president of Technology and Engineering at AMD, today confirmed that CDNA is on-track for release in 2H2020 for HPC computing. The confirmation was (adequately) given during Dell's EMC High-Performance Computing Online event. This confirms that AMD is looking at a busy 2nd half of the year, with both Zen 3, RDNA 2 and CDNA product lines being pushed to market.

CDNA is AMD's next push into the highly-lucrative HPC market, and will see the company differentiating their GPU architectures through market-based product differentiation. CDNA will see raster graphics hardware, display and multimedia engines, and other associated components being removed from the chip design in a bid to recoup die area for both increased processing units as well as fixed-function tensor compute hardware. CNDA-based Radeon Instinct MI100 will be fabricated under TSMC's 7 nm node, and will be the first AMD architecture featuring shared memory pools between CPUs and GPUs via the 2nd gen Infinity Fabric, which should bring about both throughput and power consumption improvements to the platform.

AMD today announced its Radeon Pro VII professional graphics card targeting 3D artists, engineering professionals, broadcast media professionals, and HPC researchers. The card is based on AMD's "Vega 20" multi-chip module that incorporates a 7 nm (TSMC N7) GPU die, along with a 4096-bit wide HBM2 memory interface, and four memory stacks adding up to 16 GB of video memory. The GPU die is configured with 3,840 stream processors across 60 compute units, 240 TMUs, and 64 ROPs. The card is built in a workstation-optimized add-on card form-factor (rear-facing power connectors and lateral-blower cooling solution).

What separates the Radeon Pro VII from last year's Radeon VII is full double precision floating point support, which is 1:2 FP32 throughput compared to the Radeon VII, which is locked to 1:4 FP32. Specifically, the Radeon Pro VII offers 6.55 TFLOPs double-precision floating point performance (vs. 3.36 TFLOPs on the Radeon VII). Another major difference is the physical Infinity Fabric bridge interface, which lets you pair up to two of these cards in a multi-GPU setup to double the memory capacity, to 32 GB. Each GPU has two Infinity Fabric links, running at 1333 MHz, with a per-direction bandwidth of 42 GB/s. This brings the total bidirectional bandwidth to a whopping 168 GB/s—more than twice the PCIe 4.0 x16 limit of 64 GB/s.

AMD at its 2020 Financial Analyst Day event unveiled its upcoming CDNA GPU-based compute accelerator architecture. CDNA will complement the company's graphics-oriented RDNA architecture. While RDNA powers the company's Radeon Pro and Radeon RX client- and enterprise graphics products, CDNA will power compute accelerators such as Radeon Instinct, etc. AMD is having to fork its graphics IP to RDNA and CDNA due to what it described as market-based product differentiation.

Data centers and HPCs using Radeon Instinct accelerators have no use for the GPU's actual graphics rendering capabilities. And so, at a silicon level, AMD is removing the raster graphics hardware, the display and multimedia engines, and other associated components that otherwise take up significant amounts of die area. In their place, AMD is adding fixed-function tensor compute hardware, similar to the tensor cores on certain NVIDIA GPUs.

AMD Financial Analyst Day presents an opportunity for AMD to talk straight with the finance industry about the company's current financial health, and a taste of what's to come. Guidance and product teasers made during this time are usually very accurate due to the nature of the audience. In this live blog, we will post information from the Financial Analyst Day 2020 as it unfolds.20:59 UTC: The event has started as of 1 PM PST. CEO Dr Lisa Su takes stage.

AMD has been on a roll in both consumer, professional, and exascale computing environments, and it has just snagged itself another hugely important contract. The US Department of Energy (DOE) has just announced the winners for their next-gen, exascale supercomputer that aims to be the world's fastest. Dubbed "El Capitan", the new supercomputer will be powered by AMD's next-gen EPYC Genoa processors (Zen 4 architecture) and Radeon GPUs. This is the first such exascale contract where AMD is the sole purveyor of both CPUs and GPUs, with AMD's other design win with EPYC in the Cray Shasta being paired with NVIDIA graphics cards.

El Capitan will be a $600 million investment to be deployed in late 2022 and operational in 2023. Undoubtedly, next-gen proposals from AMD, Intel and NVIDIA were presented, with AMD winning the shootout in a big way. While initially the DOE projected El Capitan to provide some 1.5 exaflops of computing power, it has now revised their performance goals to a pure 2 exaflop machine. El Capitan willl thus be ten times faster than the current leader of the supercomputing world, Summit.

With its next-generation "Zen 3" CPU microarchitecture designed for the 7 nm EUV silicon fabrication process, AMD could bid the "Zen" compute complex or CCX farewell, heralding chiplets with monolithic last-level caches (L3 caches) that are shared across all cores on the chiplet. AMD embraced a quad-core compute complex approach to building multi-core processors with "Zen." At the time, the 8-core "Zeppelin" die featured two CCX with four cores, each. With "Zen 2," AMD reduced the CPU chiplet to only containing CPU cores, L3 cache, and an Infinity Fabric interface, talking to an I/O controller die elsewhere on the processor package. This reduces the economic or technical utility in retaining the CCX topology, which limits the amount of L3 cache individual cores can access.

This and more juicy details about "Zen 3" were put out by a leaked (later deleted) technical presentation by company CTO Mark Papermaster. On the EPYC side of things, AMD's design efforts will be spearheaded by the "Milan" multi-chip module, featuring up to 64 cores spread across eight 8-core chiplets. Papermaster talked about how the individual chiplets will feature "unified" 32 MB of last-level cache, which means a deprecation of the CCX topology. He also detailed an updated SMT implementation that doubles the number of logical processors per physical core. The I/O interface of "Milan" will retain PCI-Express gen 4.0 and eight-channel DDR4 memory interface.

AMD invited TechPowerUp to their launch event and editor's day coverage of Zen 2 EPYC processors based on the 7 nm process. The event was a day-long affair which included product demos and tours, and capped off with an official launch presentation which we are able to share with you live as the event goes on. Zen 2 with the Ryzen 3000-series processors ushered in a lot of excitement, and for good reason too as our own reviews show, but questions remained on how the platform would scale to the other end of the market. We already knew, for example, that AMD secured many contracts based on their first-generation EPYC processors, and no doubt the IPC increase and expected increased core count would cause similar, if not higher, interest here. We also expect to know shortly about the various SKUs and pricing involved, and also if AMD wants to shed more light on the future of the Threadripper processor family. Read below, and continue past the break, for our live coverage.21:00 UTC: Lisa Su is on the stage at the Palace of Fine Arts events venue in San Francisco to present AMD's latest developments on EPYC for datacenters, using the Zen 2 microarchitecture.21:10 UTC: AMD focuses not just on delivering a single chip, but it's goal is to deliver a complete solution for the enterprise.

AMD (NASDAQ:AMD) today announced revenue for the second quarter of 2019 of $1.53 billion, operating income of $59 million, net income of $35 million and diluted earnings per share of $0.03. On a non-GAAP basis, operating income was $111 million, net income was $92 million and diluted earnings per share was $0.08.

"I am pleased with our financial performance and execution in the quarter as we ramped production of three leadership 7nm product families," said Dr. Lisa Su, AMD president and CEO. "We have reached a significant inflection point for the company as our new Ryzen, Radeon and EPYC processors form the most competitive product portfolio in our history and are well positioned to drive significant growth in the second half of the year."

An AMD-based system's most important performance pairing lies in the CPU and system RAM, as a million articles written ever since the introduction of AMD's first generation Ryzen CPUs have shown (remember the races for Samsung B-die based memory?). There are even tools that allow you to eke out the most performance out of your AMD system via fine memory overclocking and timings adjustment, which just goes to show the importance the enthusiast community derives from such tiny details that maximize your AMD Zen-based CPU performance. Now, notorious leaker @momomo_us has seemingly confirmed that AMD has worked wonders on its memory controller, achieving a base JEDEC 3200 MHz specification - up from the previously officially supported DDR4-2666 speeds in the first-gen Ryzen (updated to DDR4-2933 speeds on the 12 nm update).

AMD's 3rd generation Ryzen (3000-series) processors will overcome a vast number of memory limitations faced by older Ryzen chips. With Zen 2, the company decided to separate the memory controller from the CPU cores into a separate chip, called "IO die". Our resident Ryzen memory guru Yuri "1usmus" Bubliy, author of DRAM Calculator for Ryzen, found technical info that confirms just how much progress AMD has been making.

The third generation Ryzen processors will be able to match their Intel counterparts when it comes to memory overclocking. In the Zen 2 BIOS, the memory frequency options go all the way up to "DDR4-5000", which is a huge increase over the first Ryzens. The DRAM clock is still linked to the Infinity Fabric (IF) clock domain, which means at DDR4-5000, Infinity Fabric would tick at 5000 MHz DDR, too. Since that rate is out of reach for IF, AMD has decided to add a new 1/2 divider mode for their on-chip bus. When enabled, it will run Infinity Fabric at half the DRAM actual clock (eg: 1250 MHz for DDR4-5000).

AMD will launch its 3rd generation Ryzen 3000 Socket AM4 desktop processors in 2019, with a product unveiling expected mid-year, likely on the sidelines of Computex 2019. AMD is keeping its promise of making these chips backwards compatible with existing Socket AM4 motherboards. To that effect, motherboard vendors such as ASUS and MSI began rolling out BIOS updates with AGESA-Combo 0.0.7.x microcode, which adds initial support for the platform to run and validate engineering samples of the upcoming "Zen 2" chips.

At CES 2019, AMD unveiled more technical details and a prototype of a 3rd generation Ryzen socket AM4 processor. The company confirmed that it will implement a multi-chip module (MCM) design even for their mainstream-desktop processor, in which it will use one or two 7 nm "Zen 2" CPU core chiplets, which talk to a 14 nm I/O controller die over Infinity Fabric. The two biggest components of the IO die are the PCI-Express root complex, and the all-important dual-channel DDR4 memory controller. We bring you never before reported details of this memory controller.

AMD today announced the AMD Radeon Instinct MI60 and MI50 accelerators, the world's first 7nm datacenter GPUs, designed to deliver the compute performance required for next-generation deep learning, HPC, cloud computing and rendering applications. Researchers, scientists and developers will use AMD Radeon Instinct accelerators to solve tough and interesting challenges, including large-scale simulations, climate change, computational biology, disease prevention and more.

"Legacy GPU architectures limit IT managers from effectively addressing the constantly evolving demands of processing and analyzing huge datasets for modern cloud datacenter workloads," said David Wang, senior vice president of engineering, Radeon Technologies Group at AMD. "Combining world-class performance and a flexible architecture with a robust software platform and the industry's leading-edge ROCm open software ecosystem, the new AMD Radeon Instinct accelerators provide the critical components needed to solve the most difficult cloud computing challenges today and into the future."

AMD has made a blog post describing an upcoming feature for their Threadripper processors called "Dynamic Local Mode", which should help a lot with gaming performance on AMD's latest flagship CPUs.Threadripper uses four dies in a multi-chip package, of which only two have a direct access path to the memory modules. The other two dies have to rely on Infinity Fabric for all their memory accesses, which comes with a significant latency hit. Many compute-heavy applications can run their workloads in the CPU cache, or require only very little memory access; these are not affected. Other applications, especially games, spread their workload over multiple cores, some of which end up with higher memory latency than expected, which results in a suboptimal performance.

xGMI (inter-chip global memory interconnect) is a cable-capable version of AMD's Infinity Fabric interconnect. A line of code in the latest version of AMDGPU Linux drivers reveals that "Vega 20" will support xGMI. This line tells the driver to check the state of xGMI link. A practical implementation of this could be inter-card high-bandwidth bridge connectivity that would otherwise saturate the PCI-Express host bus; similar to NVIDIA's usage of the new NVLink bridge for Quadro and Tesla products based on its "Volta" and "Turing" GPU architectures.

By no means should xGMI and NVLink implementations be interpreted as a coming back of multi-GPU to the gaming space. There are still no takers for DirectX 12 multi-GPU, and fewer AAA games support SLI or CrossFire. Even at higher resolutions/refresh-rates, existing SLI/CrossFire physical-layer standards have sufficient bandwidth for multi-GPU. The upcoming GeForce RTX 2000 graphics cards feature a new multi-GPU connector that's physically NVLink, but this is probably an attempt by NVIDIA to discard the legacy SLI bus and minimize redundant interfaces on its silicon. The TU102 and TU104 chips are implemented in the enterprise segment with the Quadro RTX family. The main application of xGMI/NVLink is to make multi-GPU hardware setups abstract to deep-learning software, so hardware can scale in the background with memory access spanning multiple GPUs. "Vega 20" will be launched in Radeon Pro and Radeon Instinct avatars late-2018.

AMD announced its second-generation Ryzen Threadripper high-end desktop (HEDT) processor series, succeeding its lean and successful first-generation that disrupted much of Intel's Core X HEDT series, forcing Intel to open up new high-core-count (HCC) market segments beyond its traditional $1000 price-point. AMD's 16-core $999 1950X proved competitive with even Intel's 12-core and 14-core SKUs priced well above the $1200-mark; and now AMD looks to beat Intel at its game, with the introduction of new 24-core and 32-core SKUs at prices that are sure to spell trouble for Intel's Core X HCC lineup. The lineup is partially open to pre-orders, with two SKUs launching within August (including the 32-core one), and two others in October.

At the heart of AMD's second-generation Ryzen Threadripper is the new 12 nm "Pinnacle Ridge" die, which made its debut with the 2nd Generation Ryzen AM4 family. This die proved to introduce 3-5 percent IPC improvements in single-threaded tasks, and multi-threaded improvements with an improved Precision Boost II algorithm, which boosted frequencies of each of 8 cores on-die. The Threadripper is still a multi-chip module, with 2 to 4 of these dies, depending on the SKU. There are four of these - the 12-core/24-thread Threadripper 2920X, the 16-core/32-thread Threadripper 2950X; the 24-core/48-thread Threadripper 2970WX, and the flagship 32-core/64-thread Threadripper 2990WX.

With Moore's Law being pronounced as within its death throes, historic monolithic die designs are becoming increasingly expensive to manufacture. It's no secret that both AMD and NVIDIA have been exploring an MCM (Multi-Chip-Module) approach towards diverting from monolithic die designs over to a much more manageable, "chiplet" design. Essentially, AMD has achieved this in different ways with its Zen line of CPUs (two CPU modules of four cores each linked via the company's Infinity Fabric interconnect), and their own R9 and Vega graphics cards, which take another approach in packaging memory and the graphics processing die in the same silicon base - an interposer.

AMD is pinning a lot of hopes on its upcoming Ryzen 2000G "Raven Ridge" desktop APU family, which combine a quad-core "Zen" CPU with a larger-than-expected integrated GPU based on the latest "Vega" architecture. While Intel's iGPU design focus for its "Coffee Lake-S" processors continues to be hardware-accelerated 4K video playback, and non-gaming tasks; AMD promises a more wholesome solution. The integrated Radeon Vega 11 graphics of the Ryzen 5 2400G features 11 "Vega" NGCUs (next-generation compute units), which translates to 704 stream processors, 44 TMUs (@ 4 TMUs per NGCU), 8 or 16 ROPs, and a bandwidth-rich pathway to the APU's dual-channel DDR4-2933 capable IMC, thanks to AMD's new Infinity Fabric interconnect.

In its pre-launch press-deck for the Ryzen 3 2200G and Ryzen 5 2400G, AMD did the obvious - comparing a similarly priced Intel Core i5-8400 six-core processor (MSRP: $189) with its faster Ryzen 5 2400G (MSRP: $169.99) at gaming, highlighting its products key promise - enabling 1080p gaming with many of the newer AAA titles. In AMD's testing, the Radeon Vega 11 iGPU keeps frame-rates well above 30 fps at 1080p. In key popular titles such as "Battlefield 1," the frame-rates cross 50 fps, titles like "Overwatch" and "Rocket League" are almost that fast. "Skyrim" approaches 96 fps, while "The Witcher 3" stays barely above 30 fps. The i5-8400 with its UHD 620 graphics barely touches the 30 fps mark in any of the games, at 1080p. Even taking into account AMD's marketing hyperbole, the Radeon Vega 11 seems capable of running most eSports titles at resolutions above 1600 x 900, which should particularly interest iCafes and gamers on a shoestring budget.

In what is usually described as a tweetstorm, AMD's RTG leader Raja Koduri weighed in on AMD's RX Vega reception and perception from both the public and reviewers. There are some interesting tidbits there; namely, AMD's option of setting the RX vega parts at frequencies and voltages outside the optimal curve for power/performance ratios, in a bid to increase attractiveness towards the performance/$ crowds.

However, it can be said that if AMD had done otherwise, neither gamers nor reviewers would have been impressed with cards that potentially delivered less performance than their NVIDIA counterparts, while consuming more power all the same (even if consuming significantly less wattage). At the rated MSRP (and that's a whole new discussion), this RTG decision was the best one towards increasing attractiveness of RX Vega offerings. However, Raja Koduri does stress Vega's dynamic performance/watt ratios, due to the usage of specially defined power profiles.To our forum-walkers: this piece is marked as an editorial

AMD, presenting at a HotChips talk, packed with VLSI gurus, defended its decision to make AMD EPYC enterprise processors in the socket SP3r2 package a multi-chip module (MCM) of four 8-core "Summit Ridge" dies, rather than building a monolithic 32-core die. For starters, it stressed on the benefits of a single kind of silicon, which it can use across its performance-desktop, high-end desktop, and enterprise product-stacks; which translates into higher yields. "Summit Ridge" is the only CPU silicon based on the "Zen" micro-architecture, with the company giving finishing touches to the second silicon, codenamed "Raven Ridge," which will power mobile and desktop APUs. AMD has to pick the best-performing dies out of a common bin. The top 5% dies go into powering the company's Ryzen Threadripper HEDT processors, and a higher percentile go into making EPYC.

The relatively smaller 8-core common die has an inherently higher yield than a larger chip due to the rule of inverse-exponential reduction in yield with increasing die-size. This, coupled with the R&D costs that would have gone into developing the hypothetical monolithic 32-core "Zen" based silicon, works out to a significant cost saving for the company. A 4-die/32-core MCM is 0.59X the cost of a hypothetical monolithic 32-core die, according to the company, which is a cost-saving that enables the company to aggressively price its products. The slide AMD used in its presentation also confirms that each 8-core "Summit Ridge" die features four external Infinity Fabric links, besides the one that connects the two CCX units with each other. On a 4-die EPYC MCM, three out of four of those external IF links wire out to the neighboring dies, and one link per die probably wires out to a neighboring socket on 2P machines.

There are two kinds of desktop CPU platforms. The mainstream tier runs from two cores up to eight, and it's great for gaming and general use. Its high-end sibling takes everything up a level with more cores, more memory channels, and more bandwidth for graphics and storage. A considerable upgrade in every regard, this high-end desktop platform appeals to power users, content creators, and prosumers who want to blur the line between desktop and workstation. AMD's Threadripper CPU is the latest addition to the desktop's heavyweight division, and it walks into the ring with an entourage of SocketTR4 motherboards in tow. This guide explains the ASUS and ROG family to help you pick the best X399 motherboard for your high-end desktop or gaming PC.

All of our X399 boards share core DNA that includes one-touch overclocking, refined cooling control, and improved RGB lighting. Yet they each have their own distinct flavor as well. The ROG Zenith Extreme brings Threadripper into the world of premium dream PCs with provisions for custom liquid cooling and 10G networking. With the Strix X399-E Gaming, hardcore gamers can build stylish rigs with power to spare for high-quality streaming. And then there's the Prime X399-A and its well-rounded foundation channeling the professional side of the platform's prodigious power. Which X399 motherboard should you buy for your build? Let's find out.

AMD today officially announced some more details on its brain-child and market-stormer Ryzen Threadripper HEDT line of CPUs. Ryzen is a true new stand-alone architecture for AMD, the result of more than four years of careful planning and silicon design towards reaching a truly scalable, highly-flexible, non-glued together MCM design that could power all experiences and workloads through a single architecture design. The Ryzen architecture is already powering desktops with Ryzen 3, 5 and 7 desktop CPUs; has extended to server-side deployments through its EPYC line-up and will begin shipping for professionals with Ryzen PRO starting in Q3 2017. Also announced was that it will find its way to mobile APUs around Q4, paired with the new Vega graphics microarchitecture; and will even power professional-geared mobile solutions in 1H18. But more immediately, it's coming to the HEDT market. And AMD is putting that fight in the hands of Threadripper.

AMD pits its HEDT line-up to developers, researchers, prosumers, creators, and even multi-tasking gamers. Increased compute capabilities with up to 16 cores and 32 threads; larger memory footprint, increased I/O and storage, and support for many more GPUs and PCIe lanes ensure a stable, impressive platform for today's large data sets and tomorrow's exponentially more resource-intensive workloads. AMD will execute this with a three-pronged approach. There will be three processor models on offer for their HEDT platform. The $999 TR 1950X and $799 TR 1920X are known quantities already, with their respective 16 cores (32 threads) and 12 cores (24 threads). The new addition, however, comes in the form of the $549 TR 1900X, which offers not only 8 cores (16 threads) and 3.8 GHz base, 4.0 GHz boost clocks, but a clear upgrade path within AMD's new platform. Say what you will about AMD's offerings and execution, one thing is for sure: Zen and all the silicon it powers have prompted a reshuffle of the CPU landscape as we hadn't seen in years. Coincidence? AMD doesn't think so.

So, yes, Intel, I think the AMD engineers who have developed the Zen architecture from the ground-up would take issue with that. Especially when AMD's "Glued-together" dies actually wipe the proverbial floor with the blue company's chips in power-performance ratios, and deliver much better multi-threaded performance than Intel's offerings. Not bad for a "Glued-together" solution, I'd say.

Our resident W1zzard had this to say regarding AMD's latest CPUs: "The SenseMi power-management system seems to be working well in idle, with the 8-core machine drawing the same amount of power as Intel's quad-core "Kaby Lake" machine." And "At stock speeds, the energy-efficiency of Ryzen is truly phenomenal. Prime95 loads all cores and threads on the chip, and the Ryzen ends up with as much power draw as the quad-core Intel i7-7700K. The high power draw result of the overclocked chip is due to the increased voltage needed to achieve stable operation." And let's not forget this: This is epic. We're assuming you've sifted through our game-test results before seeing this page, and so you'll find that the gaming power draw of the 8-core Ryzen makes Intel's quad-core i7-7700K look bad. Power draw is as much as 30W lesser! Ryzen is hands down the most energy-efficient performance CPU AMD ever made, and easily outclasses Intel's 14 nm "leadership." Good show."

Today, AMD, along with its global ecosystem of server customers and partners, launched the EPYC 7000 series of high-performance datacenter processors. With up to 32 high-performance "Zen" cores and an unparalleled feature set, the record-setting AMD EPYC design delivers greater performance across a full range of integer, floating point, memory bandwidth, and I/O benchmarks and workloads.

Intel's "Xeon Scalable" lineup is designed to compete directly with AMD's Naples platform. Naples, a core-laden, high performance server platform that relies deeply on linking multiple core complexes together via AMD's own HyperTransport derived Infinity Fabric Interconnect has given intel some challenges in terms of how to structure its own high-core count family of devices. This has led to a new mesh-based interconnect technology from Intel.

TechPowerUp and G.Skill Memory bring you three more reasons to take the AMD Ryzen leap, with the "Game Faster with Flare X" Giveaway. Up for grabs are three G.Skill Flare X 16 GB (2x 8GB) dual-channel DDR4-3200 memory kits, which are based on Samsung b-die DRAM chips, and are recommended by AMD for the best performance on its Ryzen series desktop processors. The Flare X series kits are renowned for reliably sustaining DDR4-3200 speeds on Ryzen machines, which have a direct impact on their performance, since DRAM clock is synced with the clock speed of the Infinity Fabric interconnect between the two CCX quad-core units on Ryzen processors. The giveaway is open worldwide.For more information, and to participate, visit this page.
