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.

Ahead of the Supercomputing conference next week, Intel has announced a new market segment for Xeons called Cascade Lake Advanced Platform (CXL-AP). This represents a new, higher core count option in the Xeon Scalable family, which currently tops out at 28 cores.
Through the use of a multi-chip package (MCP), Intel will now be able to offer up to 48-cores, with 12 DDR4 memory channels per socket. Cascade Lake AP is being targeted at dual socket systems bringing the total core count up to 96-cores.
Intel's Ultra Path Interconnect (UPI), introduced in Skylake-EP for multi-socket communication, is used to connect both the MCP packages on a single processor together, as well as the two processors in a 2S configuration.
Given the relative amount of shade that Intel has thrown towards AMD's multi-die design with Epyc, calling it "glued-together," this move to an MCP for a high-end Xeon offering will garner some attention.
When asked about this, Intel says that the issues they previously pointed out with aren't inherently because it's a multi-die design, but rather the quality of the interconnect. By utilizing UPI for the interconnect, Intel claims their MCP design will provide performance consistency not found in other solutions. They were also quick to point out that this is not their first Xeon design utilizing multiple packages.
Intel provided some performance claims against the current 32-core Epyc 7601, of up to 3.4X greater performance in Linpack, and up to 1.3x in Stream Triad.
As usual, whether or not these claims are validated will come down to external testing when people have these new Cascade Lake AP processors in-hand, which is set to be in the first half of 2019.
More details on the entire Cascade Lake family, including Cascade Lake AP, are set to come at next week's Supercomputing conference, so stay tuned for more information as it becomes available!

Among the various Apple announcements this week was a win for AMD, as Apple has renewed their agreement and will be using Radeon Pro Vega GPUs in it's soon to be released MacBook Pros. We aren't expecting any more big surprises from the release, such as the iPad Pro now sporting USB C, the updated GPU may be the largest change this generation but it will be appreciated by some content creators. You can read more about the various announcements over at The Inquirer.
"AMD GPUs are nothing new in Mac machines, given the MacBook Pros have previously rocked the Radeon Pro 560X, but Cupertino is now bringing AMD's Vega-based GPUs to its expensive laptops."

Now that you've had some time to digest Ken's look at the 2920X and 2970WX, take a look at how AMD's new silicon performed on other test beds. Over at The Tech Report they ran the 2920X paired with DDR4-3200 and spent a fair amount of time testing workstation tasks including DAWBench VI tests. There are also a number of games they tested which are not included in our suite so start your reading over there.
"While those figures may seem little changed from those of the Ryzen Threadripper 1920X, AMD's Precision Boost 2 technology promises a more graceful descent to that base clock as cores and threads become loaded down.""

A quick refresher and Dynamic Local Mode
In general, the rollout of AMD's second-generation Ryzen Threadripper processors has been a bit unconventional. While the full lineup was announced back in August, there has been a staggered release period.
Later in August, we first got our hands on the Threadripper 2950X and 2990WX, the 16 and 32-core variants. Even though both of these parts were reviewed at the same time, the 2990WX was available first, with the 2950X coming a few weeks later.
Now more than two months later, we are taking a look at the 12-core Threadripper 2920X and the 24-core Threadripper 2970WX which were announced alongside the Threadipper parts that have already been shipping for quite a while now.
Will these new Threadripper processors be worth the wait?

Tagged: amd, quarterly results, Q3 2018, ryzen, EPYC, Polaris, Vega, 7nm, 12nm, Intel, nvidia
This evening AMD announced their Q3 2018 results. Things were at the lower end of the guidance scale from last quarter, but the company still had some solid results. Q3 revenue was $1.65B as compared to Q3 2017’s $1.58B. It is down from the previous quarter’s high of $1.76B. At first glance this seems troubling, but the results are not as negative as one would assume. GAAP net income was a healthy $102M. Q3 2017 was at $61M while Q2 2018 was up at $116M. Profits did not fall nearly as much as one would expect with a decrease of $110M revenue quarter over quarter.
Probably the largest factor of the decrease was the negligible sales of GPUs to the crypto market. AMD had expected such a dropoff and warned about it in their Q2 guidance. That particular drop off was sudden and dramatic. AMD looks to continue to lose marketshare in add-in graphics due to their less competitive offerings across the spectrum. GeForce RTX sales of course did not impact AMD this previous quarter, but with no new AMD offerings on the horizon users look to have been waiting to see exactly what NVIDIA would release.
Ryzen sales have been steady and strong, making up some of the shortfall from the graphics market. Desktop chips are moving briskly for the company and continues to be a strong seller historically for the company. AMD is also starting to move more mobile processors, but it seems that the majority of parts are still desktop based. AMD looks to continue moving older inventory with aggressive pricing on those and manufacturing of the new 2000 series parts has been relatively smooth sailing for the company.
Enterprise, Embedded, and Semi-Custom had a strong quarter, but with less growth as some analysts had been hoping for. Semi-Custom was weaker this quarter, but IP revenue is up. Console chips are weaker at the moment due to the platforms being relatively mature and not exhibiting the sales of the previous two holiday seasons. To further offset the decrease in Semi-Custom, AMD is reporting that the enterprise products (GPU and EPYC) have seen good growth. Overall this division was down 5% from Q3 2017, but up 7% from the previous quarter.
Perhaps the most interesting figure of this is Gross Margins. AMD was able to improve margins from 36% to 40%. This 4% increase quarter on quarter is a significant jump for the company. This means that AMD continues to keep costs under control for the company and is able to deliver product more efficiently than in the year before. It is still a far cry from Intel and NVIDIA, which typically have magins between 55% to 65%. AMD has a long ways to go before reaching that kind of level. Part of the margin offset was again due to IP licensing. If IP licensing was removed then we would see 38% margins rather than 40%.
So what are the overall lessons of the past quarter? EPYC sales are not as brisk as analysts had hoped for, but they are also not non-existent. It has shown solid growth for the company and has offset shortfalls in other areas of the company. Their IP and Semi-Custom areas are still very solid, even though AMD does suffer from console lifecycles and downturns. GPUs continue to sell, but not nearly at the rate they were due to the crypto market. Their Polaris based options are well suited to compete in the sub-$300 US market. The Vega based products were finally down to MSRP, but they had a harder time going against the mature and well liked GeForce GTX 1070 and 1080 products. This will be further compounded with the introduction of the RTX products in those price ranges.
Ryzen continues to be a very good seller across the board. I had hoped that AMD would break down numbers between Ryzen CPUs and APUs, but I have not seen numbers that hint at what ratio they sell at. In retail the Ryzen 2000 series CPUs look to be some of the most popular products based on price/performance. However, retail is only a small portion of processor sales and Intel still holds the vast majority of marketshare here. AMD is competing, but they have not taken significant chunks from their competition over the past year. They have done enough to achieve several positive quarters in a row, but this is not the slam dunk that the original Athlon 64 was back in 2003/2004.
AMD expects further weakness in their results next quarter. Guidance is for revenue around $1.45B, plus or minus $50M. This is still higher than Q4 2017 results, but it is a significant drop from Q3 results. AMD expects strong Ryzen, EPYC, and datacenter GPU growth during this time. It is expected that consumer GPU and Semi-Custom will continue to drop. There does look to be a 7nm GPU introduction this next quarter, but it is probably the long rumored Vega refresh that will be aimed directly at datacenter rather than consumer.
2018 has so far been a year of solid growth and execution for AMD on the CPU side. Their GPU side has suffered a bit of a slide, but this is to be expected by how much belt-tightening AMD has done in the past several years to get their CPU architecture back on track. The lion’s share of development resources was shunted off to the CPU side while the GPU side had to fight for scraps. I believe this is no longer the case, but when development takes years for new GPUs the injection of new resources will not become apparent for a while.
2019 continues to look better for AMD as they are expecting an early release of 7nm EPYC parts which should compete very well with Intel’s 14nm based Xeon products. AMD is expecting a significant uptick in sales due to the thermals, pricing, and performance of these new Zen 2 based parts. The company also continues to point to the end of 1H for introduction of 7nm Ryzen parts based on Zen 2. These will be showing up quite a few months before Intel’s 10nm offerings will be available. Rumors have it that the new Zen 2 based parts exhibit a significant IPC increase that should make them far more competitive to the best that Intel has on the desktop and mobile markets. Combine these IPC improvements with the 7nm boost in power and clocks for the parts, and AMD could have a very good product on their hands. AMD also is expecting a 1H release of 7nm Navi GPUs which should prove to be more competitive with current NVIDIA products that rely on 16nm and 12nm process nodes from TSMC.
While Q3 was a drop in revenue for the company, their current cost structure has still allowed them to make a tidy profit. The company continues to move forward with new products and new developments.

Tagged: navi, amd, rumour, 7nm
The rumours about AMD's new 7nm Navi GPU are continuing to spread, this time via The Inquirer. They have heard tell that the chips are currently being tested, which is good news for both AMD and consumers. We know that new Vega cards will be arriving in the near future but as of now we don't know as much about the release of Navi. If they are currently testing the silicon that could imply some sort of release next year, perhaps not a full lineup but quite possibly something we can take a peek at and see how it stacks up to Turing. Lets hope it is sooner rather than later.
"Touted to be the next graphics accelerators to take the fight to Nvidia with its Turing-based GeForce RTX graphics cards, Navi is set to use a 7nm process which promises to get more power out of GPU silicon."

With the advent of the 9th generation of Core processors from Intel, we see the market return to what we have been used to in the past. Intel's offering is now faster and more effective than AMD's Ryzen, but it is also significantly more expensive. Instead of getting an APU and heatsink for ~$300, you will be paying ~$530 for just the processor with no cooler. That said the i9-9900K makes sense for those who have spent the money on an RTX 2080 Ti and a high resolution monitor, since they've already set a large budget; while those with less lofty dreams will be very happy with the Ryzen 7 2700X.
The question of overclocking is an interesting one, as Ken had no luck getting the chip to run above 5GHz. [H]ard|OCP had a slightly better experience, hitting 5.14GHz with a 3600MHz memory bus, which could not match the content creation power of Threadripper 2 even though it was sucking down more juice. Check out their review and then browse through the ones below.
"The new 9th generation Intel i9-9900K CPU is upon us! AMD has been pushing into Intel's desktop market and Intel knows it. Today Intel is pulling the curtain back on "not paid for" reviews and we are happy to be serving you one of those up here today. Is the i9-9900K better than the Ryzen 7 2700X, and is it worth the staggering price premium?"

One of the most radical changes to happen in the last two years in the PC hardware space has to be the launch of AMD's Ryzen processors. Despite the failure that was the FX-series with their Bulldozer architecture, AMD managed to shock the industry with the performance of their next generation Zen architecture.
After generations upon generations of consumer processors topping out at four cores going back to the Core 2 days, Intel finally launched their first 6-core processor for consumers with the 8700K almost exactly a year ago.
AMD's continued to persevere with the launch of the second generation Ryzen 7 2700X earlier this year, which managed to improve the single-threaded performance gap between AMD and Intel.
Still, this performance gap existed, leaving room for what Intel is launching today, their first 8-core mainstream consumer processor, the Core i9-9900K. Finally having core count parity with AMD, and still holding an advantage in single-threaded performance, this launch has garnered a lot of attention.
