EPYC Linux performance from AMD

Tagged: linux, EPYC 7601, EPYC

Phoronix have been hard at work testing out AMD's new server chip, specifically the 2.2/2.7/3.2GHz EPYC 7601 with 32 physical cores.  The frequency numbers now have a third member which is the top frequency all 32 cores can hit simultaneously, for this processor that would be 2.7GHz.  Benchmarking server processors is somewhat different from testing consumer CPUs, gaming performance is not as important as dealing with specific productivity applications.   Phoronix started their testing of EPYC, in both NUMA and non-NUMA configurations, comparing against several Xeon models and the performance delta is quite impressive, sometimes leaving even a system with dual Xeon Gold 6138's in the dust.  They also followed up with a look at how EPYC compares to Opteron, AMD's last server offerings.  The evolution is something to behold.

"By now you have likely seen our initial AMD EPYC 7601 Linux benchmarks. If you haven't, check them out, EPYC does really deliver on being competitive with current Intel hardware in the highly threaded space. If you have been curious to see some power numbers on EPYC, here they are from the Tyan Transport SX TN70A-B8026 2U server. Making things more interesting are some comparison benchmarks showing how the AMD EPYC performance compares to AMD Opteron processors from about ten years ago."

Core i7-6700K and Core i5-6600K finally see end of life by Intel

Subject: Processors | September 6, 2017 - 12:06 PM |
Tagged: Intel, 6700k, 6600k

Initially launched in August of 2015, the Skylake consumer desktop processors are finally ramping down at Intel production facilities. Based on this Intel Product Change Notification, the widely coveted Core i7-6700K and Core i5-6600K, along with several other parts, are being EOL'd (end of life).

If you are an OEM or just really love building around these parts, you still have some time to get your orders in. You have until March 30, 2018 to place your final requests and the final shipment date will be a year from today. If you ever were curious how complex the ramp down on parts that ship to thousands of different customers in consumer, enterprise, and embedded markets, the table above should give you a glimpse.

(Probably that 3017 date is a typo...)

With the focus for Intel squarely on the Kaby Lake Core i7-7700K and Core i5-7600K, in addition to the upcoming Coffee Lake refresh 8000-series, enthusiasts might be wondering why it took Intel so long to shut things down on this set of Skylake parts.

I think it is safe to say that this marks the end of an interesting window of time for Intel, where it had clear and uncontested dominance of the consumer processor market. Re-reading my conclusion to the 6700K review reveals almost no mention of a relevant AMD competing part, making today's situation with Ryzen and Threadripper all the more impressive.

Intel Skylake-X 18-core Die Pictured. It's Massive.

Subject: Processors | September 5, 2017 - 11:16 AM |
Tagged: skylake-x, Intel

We are just starting to ramp back up here after the long holiday weekend, so let's start with something that is both interesting and easy to absorb. High-profile overclocker Der8auer has gotten his hands on an 18-core Skylake-X processor and did exactly what you would expect - delidded it. 

The takeaway from this is two-fold. First, the die appears very clean, indicating that Intel has still not decided to solder these high-end processors and is going with a standard thermal interface between the die and the heat spreader.

Also...it's friggin huge. Look at the 10-core die from the Core i9-7900X that was observed earlier this year and compare it to the image above. 

10c-die.jpg

Though the camera angles aren't ideal, comparing the layout of the die to the physical substrate, which IS the same size between all the Skylake-X processors, you can see how much larger this 18-core die truly is. Expect to see the 18, 16, 14, and even the 12-core processors to use the same physical die.

Tagged: Xeon W, xeon scalable, xeon, workstation, processor, Intel, cpu

Intel has officially announced their new workstation processor lineup, with Xeon Scalable and Xeon W versions aimed at both professional and mainstream workstation systems.

"Workstations powered by Intel Xeon processors meet the most stringent demands for professionals seeking to increase productivity and rapidly bring data to life. Intel today disclosed that the world-record performance of the Intel Xeon Scalable processors is now available for next-generation expert workstations to enable photorealistic design, modeling, artificial intelligence (AI) analytics, and virtual-reality (VR) content creation."

Slide 1.png

The first part of Intel’s product launch announcement are the new Xeon Scalable processors, first announced in July, and these are dual-socket solutions targeting professional workstations. Versions with up to 56 cores/112 threads are available, and frequencies of up to 4.20 GHz are possible via Turbo Boost. Intel is emphasising the large performance impact of upgrading to these new Xeon processors with a comparison to older equipment (a trend in the industry of late), which is relevant when considering the professional market where upgrades are far slower than the enthusiast desktop segment:

“Expert workstations will experience up to a 2.71x boost in performance compared to a 4-year-old system and up to 1.65x higher performance compared to the previous generation.”

Slide 2.png

The second part of announcement are new Xeon W processors, which will be part of Intel’s mainstream workstation offering. These are single-socket processors, with up to 18 cores/36 threads and Turbo Boost frequencies up to 4.50 GHz. The performance impact with these new Xeon W CPUs compared to previous generations is not as great as the Xeon Scalable processors above, as Intel offers the same comparison to older hardware with the Xeon W:

“Mainstream workstations will experience up to a 1.87x boost in performance compared to a 4-year-old system4 and up to 1.38x higher performance compared to the previous generation.”

XSPC's plus sized Raystorm leaves no Thread exposed; it's Ripper

Subject: Processors | August 24, 2017 - 12:43 PM |
Tagged: XSPC, amd, Threadripper, overclocking, Raystorm

For those convinced that the Threadripper is being held back by poorly endowed partners, [H]ard|OCP received the new XSPC RayStorm which has a cold plate as large as Threadrippers heatspreader.  As you can see from the picture, new habits will need to e learned when spreading the TIM on such a large area so keep an eye out for tips or carefully experiment on your own.  The heatsink let [H] reach a solid 4GHz on all 16 cores with a 3200MHz memory clock, at significantly lower voltages than Ryzen required to reach the same frequency.  Even better news is that this is not the limit, [H] intends to test again using a more powerful radiator and expects to see an even better overclock.

"XSPC got us over one of its first waterblocks specifically designed to help handle Ryzen Threadripper CPU's heat while overclocking. We give you a quick unboxing, break down the block itself, and then we look at Threadripper long-term performance. We finally get it dialed in at 4GHz."

King of content creation, Threadripper takes the crown

Subject: Processors | August 10, 2017 - 03:55 PM |
Tagged: Zen, X399, Threadripper, ryzen, amd, 1950x, 1920x

When you look at the results Ryan posted, it was clear that when it comes to video rendering and other content creation it is AMD's chip which comes out ahead in performance, and at a better price point that Intel's Core i9.  Don't just take our word for it, many others reviewed the new chips, including [H]ard|OCP.  Their results agree, showing that the only advantage Intel has is in single threaded applications, in which case the frequency of the 4.6GHz Intel part can outpace the 4GHz Threadripper.  Those picking up Threadripper have no interest in single threaded applications, they prefer their programs to be spread across multiple cores and not only does Threadripper have the most cores, it allows you to flip between NUMA and UMA depending on your preference.  Check out [H]'s review here before continuing below the fold.

"The day is finally upon us that many CPU enthusiasts have been waiting for. We get to see what AMD's new Threadripper CPU is all about in terms of performance, and in attempts to cool the beast. There has been no lack of hype for months now, so let's see if it is all justified."

Who is this for, anyway?

Today is a critically important day for AMD. With the launch of reviews and the on-sale date for its new Ryzen Threadripper processor family, AMD is reentering the world of high-end consumer processors that it has been absent from for a decade, if not longer. Intel has dominated this high priced, but high margin, area of the market since the release of the Core i7-900 series of Nehalem CPUs in 2008, bringing workstation and server class hardware down to the content creator and enthusiast markets. Even at that point AMD had no competitive answer, with only the Phenom X4 in our comparison charts. It didn’t end well.

AMD has made no attempt of stealth with the release of Ryzen Threadripper, instead adopting the “tease and repeat” campaign style that Radeon has utilized in recent years for this release. The result of which is an already-knowledgeable group of pre-order ready consumers; not a coincidence. Today I will summarize the data we already know for those of you just joining us and dive into the importance of the new information we can provide today. That includes interesting technical details on the multi-die implementation and latency, overclocking, thermals, why AMD has a NUMA/UMA issue, gaming performance and of course, general system and workload benchmarks.

Strap in.

A Summary of Threadripper

AMD has been pumping up interest and excitement for Ryzen Threadripper since May, with an announcement of the parts at the company’s financial analyst day. It teased 16 cores and 32 threads of performance for a single consumer socket, something that we had never seen before. At Computex, Jim Anderson got on stage and told us that each Threadripper processor would have access to 64 lanes of PCI Express, exceeding the 40 lanes of Intel’s top HEDT platforms and going well above the 28 lanes that the lower end of its family offers.

05.jpg

In mid-July the official announcement of the Ryzen Threadripper 1950X and 1920X occurred, with CEO Lisa Su and CVP John Taylor having the honors. This announcement broke with most of the important information including core count, clock speeds, pricing, and a single performance benchmark (Cinebench). On July 24th we started to see pictures of the Threadripper packaging show up on AMD social media accounts, getting way more attention than anyone expected a box for a CPU could round up. At the end of July AMD announced a third Threadripper processor (due in late August). Finally, on August 3rd, I was allowed to share an unboxing of the review kit and the CPU itself as well as demonstrate the new installation method for this sled-based processor.

It’s been a busy summer.

We can't benchmark Threadripper yet, but we can cool it

Subject: Processors | August 8, 2017 - 03:01 PM |
Tagged: amd, Threadripper, water cooling, lapping

It has been a long time since lapping was a requirement to get the best cooling for your new processor, however it might be making a comeback.  Threadripper is endowed with a larger heatsink than your average CPU and to help you accommodate that the chip contains an Asetek mounting bracket which is compatible with most AiO coolers.  The bracket and size of the heatspreader do seem to exacerbate any curvature of the coldplate however, the Asetek AiO which [H]ard|OCP tested needed to be lapped for a proper mating.

Since they had some difficulty with AiO coolers, [H] decided to configure their own watercooler for Threadripper.  They grabbed an old Koolance water block they had handy and with a bit of time and a $10 trip to a hardware store they ended up with a much better solution.  Take peek at the process, especially if you happen to have parts lying around that you want to put back to use.

"What do you do when you don't have the proper parts that you need to water cool your new thread ripper? Make you own with trash you find around the house. Maybe even repurpose and old water block that is in your closet."

Intel Fills In the Gaps on Core X-Series Processor Specs

Subject: Processors | August 7, 2017 - 01:34 PM |
Tagged: X-Series, processor, Intel, cpu, Core i9, core i7

Intel launched the first half of its X-Series processor lineup earlier this year, releasing up to the 10-core i9-7900X. But with the upcoming release of AMD's 16-core Threadripper 1950X, the real interest among enthusiasts are the specs of Intel's high core count X-Series parts.

family-corex-ext-m-rgb-3000.png

After previously teasing partial specs for these parts, Intel today finally unveiled the complete details, starting out with the i9-7920X (12 cores/24 threads) with a 2.9GHz base and up to 4.4GHz boost clock and topping out with the i9-7980XE (18 cores/36 threads) with a 2.6GHz base and 4.4GHz max boost clock. Check the table below for the complete specifications:

From a pure core-count perspective, the Threadripper 1950X goes up against Intel's i9-7960X, but with a $700 difference in price. With Intel CPUs holding and IPC advantage over AMD, however, it's likely that the i9-7920X, and perhaps even the 7900X, will best Threadripper in certain gaming and productivity workloads.

Also interesting in Intel's announcement today are the base clocks of the 12-core i9-7920X (2.9GHz) and the 14-core i9-7940X (3.1GHz). Intel pushed the TDP of the 7940X to 165W, allowing it to increase the base clock over its 12-core counterpart. This suggests that Intel expects the 14-core 7940X, at a price-point of $1399, to be a popular choice in terms of price-to-performance.

Finally, Intel's release today reveals that all of the upcoming X-Series parts will have 44 PCIe lanes, compared to the 64 lanes AMD is offering on all Threadripper parts. There was some debate in the office this morning about how Intel's 44 lanes should cover most configurations for the foreseeable future, but this still remains one clear advantage for AMD's platform.

Intel's 4- to 10-core processors are already on the market. Intel says that the 12-core 7920X will launch August 28th, while the 14- to 18-core parts will launch about a month later, on September 25th.
