You may have never heard of Graviton before, but chances are you've interacted with one on Amazon. The current chip which powers many AWS instances is based on a Cortex-A72 design and runs 2.3GHz and was almost designed by AMD. Instead, AMD was focusing on Zen design and were not able to commit enough resources to the development of the ARM chip, which is why Amazon chose to buy Annapurna Labs outright and have the chip designed in house. We did see that AMD ARM chip, the A1100, which did not see much market success.
There is quite a story behind this, catch up on it over at The Register.
"Up until early 2015, Amazon and AMD were working together on a 64-bit Arm server-grade processor to deploy in the internet titan's data centers. However, the project fell apart when, according to one well-placed source today, "AMD failed at meeting all the performance milestones Amazon set out."

The DeepCool Captain 240 EX White is an AiO watercooler, with a 240mm radiator which is available in both RGB and non-RGB models. It is designed to cool most modern chips, apart from ThreadRipper, and [H]ard|OCP tested it with a Ryzen 7 1700 overclocked to 3.9 GHz @ 1.475V. The results were interesting, to say the least, so make sure to drop by before falling in love with this particular cooler.
"Deepcool states its mission is to provide "the best and personalized thermal solutions." Its Captain EX series of AIO CPU coolers has what it calls a "Steam Punk" look with visible liquid flow, but what we are most concerned with is just how well it cools our overclocked and over-volted Ryzen 7 processor. And it has "anti-explosion" rubber material."

AMD released an interesting update to the RX 580 today, the aptly named RX 590. It sports the same internals as the current card, with one significant difference which are the clocks. The new RX 590 sports frequencies of 1469 MHz Base, 1545 MHz Boost which is a hair over 200MHz higher than the 580 and [H]ard|OCP were able to push it up to 1670MHz with a bit of extra juice. Their findings matched Ken's, in that this new card makes NVIDIA's GTX 1060 obsolete as it outperforms it and at a better price point. The only drawback to the XFX Fatboy model reviewed is given away in the name; the card is a wee bit over 2 slots in height.
[H]'s suite of games incorporates different titles than ours so make sure you do pay them a visit.
"AMD is launching the new Radeon RX 590 GPU today, and we have a custom XFX Radeon RX 590 Fatboy OC+ video card to evaluate. With a high factory overclock, and potential for overclocking, we will compare this video card with the EVGA GTX 1060 SSC overclocked and test at 1080p and 1440p gaming."

Tagged: meltdown, spectre, amd, arm, Intel
Happy Thursday, here's some new Spectre and Meltdown vulnerabilities to cheer you up, including the first Meltdown flaw to which AMD chips are vulnerable to delayed exception handling. That brings the tally to seven Meltdown and 14 Spectre flaw variants which effect modern processor architecture; the only good news is not all chips are vulnerable to all flaws. Intel told The Register that these flaws can be mitigated with software while the researchers pointed out that these vulnerabilities were successfully carried out on patched systems; AMD declined to comment.
Of course, that doesn't matter if you choose not to install the software patches due to the performance hit which is a side effect to many of those mitigations.
"Computer security researchers have uncovered yet another set of transient execution attacks on modern CPUs that allow a local attacker to gain access to privileged data, fulfilling predictions made when the Spectre and Meltdown flaws were reported at the beginning of the year."

While 2018 so far has contained lots of talk about graphics cards, and new GPU architectures, little of this talk has been revolving around AMD. After having launched their long-awaited Vega GPUs in late 2017, AMD has remained mostly quiet on the graphics front.
As we headed into summer 2018, the talk around graphics started to turn to NVIDIA's next generation Turing architecture, the RTX 2070, 2080, and 2080 Ti, and the subsequent price creeps of graphics cards in their given product segment.
However, there has been one segment in particular that has been lacking any excitement in 2018—mid-range GPUs for gamers on a budget.
AMD is aiming to change that today with the release of the RX 590. Join us as we discuss the current state of affordable graphics cards.

The new ~$2000 i9-9980XE is a refreshed Skylake chip, using Intel's 14-nm++ process, with 18 multithreaded cores running at 3GHz with a Boost clock of 4.4GHz. If you were to lift up the lid, you would find the same Solder Thermal Interface Material we saw in the last few releases so expect some brave soul to run delidding tests at some point in the near future. As it stands now, The Tech Report's overclocking tests had the same results as Ken, with 4.5GHz across all cores being the best they could manage. While the chip does offer new features, many of them are aimed specifically at production tasks and will not benefit your gaming experience.
Check out the performance results here and below the fold.
"Intel is bolstering its Core X high-end desktop CPUs with everything in its bag of tricks, including 14-nm++ process technology, higher clock speeds, larger caches, and solder thermal interface material. We put the Core i9-9980XE to the test to see how those refinements add up against AMD's high-end desktop onslaught."

Shopping for a CPU in 2018 has been a bit of a moving target. Between the launch of AMD's Ryzen 2000 series processors in the beginning of the year, new AMD Threadripper X and WX-series products, and a consumer CPU refresh from Intel last month, it's been difficult to keep track of.
Now we are rounding out 2018 with new products for the last remaining platform that hasn't seen a refresh this year, Intel's Core X-series of processors, namely the Intel Core i9-9980XE.

Tagged: Zen 2, rome, PCI-e 4, Infinity Fabric, EPYC, ddr4, amd, 7nm
In addition to AMD's reveal of 7nm GPUs used in its Radeon Instinct MI60 and MI50 graphics cards (aimed at machine learning and other HPC acceleration), the company teased a few morsels of information on its 7nm CPUs. Specifically, AMD teased attendees of its New Horizon event with information on its 7nm "Rome" EPYC processors based on the new Zen 2 architecture.
Tom's Hardware spotted the upcoming Epyc processor at AMD's New Horizon event.
The codenamed "Rome" EPYC processors will utilize a MCM design like its EPYC and Threadripper predecessors, but increases the number of CPU dies from four to eight (with each chiplet containing eight cores with two CCXs) and adds a new 14nm I/O die that sits in the center of processor that consolidates memory and I/O channels to help even-out the latency among all the cores of the various dies. This new approach allows each chip to directly access up to eight channels of DDR4 memory (up to 4TB) and will no longer have to send requests to neighboring dies connected to memory which was the case with, for example, Threadripper 2. The I/O die is speculated by TechPowerUp to also be responsible for other I/O duties such as PCI-E 4.0 and the PCH communication duties previously integrated into each die.
"Rome" EPYC processors with up to 64 cores (128 threads) are expected to launch next year with AMD already sampling processors to its biggest enterprise clients. The new Zen 2-based processors should work with existing Naples and future Milan server platforms. EPYC will feature from four to up to eight 7nm Zen 2 dies connected via Infinity Fabric to a 14nm I/O die.
AMD CEO Lisa Su holding up "Rome" EPYC CPU during press conference earlier this year.
The new 7nm Zen 2 CPU dies are much smaller than the dies of previous generation parts (even 12nm Zen+). AMD has not provided full details on the changes it has made with the new Zen 2 architecutre, but it has apparently heavily tweaked the front end operations (branch prediction, pre-fetching) and increased cache sizes as well as doubling the size of the FPUs to 256-bit. The architectural improvements alogn with the die shrink should allow AMD to show off some respectable IPC improvements and I am interested to see details and how Zen 2 will shake out.

Tagged: AMD Radeon Instinct, MI60, MI50, 7nm, ROCm 2.0, HPC, amd
If you haven't been watching AMD's launch of the 7nm Vega based MI60 and MI50 then you can catch up right here.
You won't be gaming with these beasts, but for those working on deep learning, HPC, cloud computing or rendering apps you might want to take a deeper look. The new PCIe 4.0 cards use HBM2 ECC memory and Infinity Fabric interconnects, offering up to 1 TB/s of memory bandwidth.
The MI60 features 32GB of HBM2 with 64 Compute Units containing 4096 Stream Processors which translates into 59 TOPS INT8, up to 29.5 TFLOPS FP16, 14.7 TFLOPS FP32 and 7.4 TFLOPS FP64. AMD claims is currently the fastest double precision PCIe card on the market, with the 16GB Tesla V100 offering 7 TFLOPS of FP64 performance.
The MI50 is a little less powerful though with 16GB of HBM2, 53.6 TFLOPS of INT8, up to 26.8 TFLOPS FP16, 13.4 TFLOPS FP32 and 6.7 TFLOPS FP64 it is no slouch.
With two Infinity Fabric links per GPU, they can deliver up to 200 GB/s of peer-to-peer bandwidth and you can configure up to four GPUs in a hive ring configuration, made of two hives in eight GPU servers with the help of the new ROCm 2.0 software.
Expect to see AMD in more HPC servers starting at the beginning of the new year, when they start shipping.
