Testing Notes
For the EPYC launch, AMD sent us their best SKU: the EPYC 7601. Meanwhile Intel gave us a choice between the top bin Xeon 8180 and the Xeon 8176. Considering that the latter had 165-173W TDP, similar to AMD's best EPYC, we felt that the Xeon 8176 was the best choice.
Unfortunately, our time testing the two platforms has been limited. In particular, we only received AMD's EPYC system last week, and the company did not put an embargo on the results. This means that we can release the data now, in time to compare it to the new Skylake-SP Xeons, however it also means that we've only had a handful of days to work with the platform before writing all of this up for today's embargo. We're confident in the data, but it means that we haven't had a chance to tease out the nuances of EPYC quite yet, and that will have to be something we get to in a future article.
Meanwhile we should note that we've had to retire the bulk of our historical benchmark data, as we upgraded both our compiler and OS (see below). Due to this, we only had a very limited amount of time to run additional systems, and for that reason we've opted include Intel's Xeon E5-2690. The Sandy Bridge-EP processor is about 5 years old, and for customers who aren't upgrading their servers every single generation, it's these servers that we believe are most likely to get upgraded in this round. So for server managers looking at finally buying into new hardware, you can get an idea of much return of investment you get.
Benchmark Configuration and Methodology
All of our testing was conducted on Ubuntu Server "Xenial" 16.04.2 LTS (Linux kernel 4.4.0 64 bit). The compiler that ships with this distribution is GCC 5.4.0.
You will notice that the DRAM capacity varies among our server configurations. The reason is that we had little time left before today's launch embargo. Removing any hardware is always a risk, so we decided to run our tests without significantly changing the internal hardware of the systems we received from AMD and Intel (SSDs were still replaced). As far as we know, all of our tests fit in 128 GB, so DRAM capacity should not have much influence on performance. But it wil have a impact on total energy consumption, which we will discuss.
Last but not least, we want to note how the performance graphs have been color-coded. Orange is AMD's EPYC, dark blue is Intel's best (Skylake-SP), and light blue is the previous generation Xeons (Xeon E5-v4) . Gray has been used for the soon-to-be-replaced Xeon v1.

Other Notes
Both servers are fed by a standard European 230V (16 Amps max.) power line. The room temperature is monitored and kept at 23°C by our Airwell CRACs.

Always reference the newest piece, especially the main review.Or we'd spend half of our time going back and updating old pieces and reviews with new data.

On the POV-RAY benchmark, shouldn't that read as almost 16% faster than the dual 2699 v4 and 32% faster than the dual 8176?scienceomatica - Tuesday, July 11, 2017 - link
I think that a fair game would be to compare the top offer of one and the other manufacturer, in other words, the Xeon 8180 should be included in the benchmark regardless of the aspect of the price. Then the difference would be quite in favor of the Intel processor, although it has few cores less.Tamz_msc - Tuesday, July 11, 2017 - link
Will we get to see more FP HPC-oriented workloads like SPECfp2006 or even 2017 being discussed in a future article?lefty2 - Tuesday, July 11, 2017 - link
I can summarize this article: "$8719 chip beaten by $4200 chip in everything except database and Appache spark."Well done Intel, another Walletripper!

Then why did google att aws etc upgraded to skylake. They could have saved billions of dollars.Shankar1962 - Wednesday, July 12, 2017 - link
Look at what big players upgrading to skylake reportedThese are real workloads
No one cares about labs
These numbers decide who wins and who loses
No wonder AMD sells at $4200

Pricing on page 10 should reflect that the 2P EPYC prices are for 2 processors, not per CPU. The price of Xeons is per CPU.coder543 - Tuesday, July 11, 2017 - link
That doesn't seem true. The prices they currently have seem to be correct. Got a source?
