Multi-Threaded Integer Performance
While stand-alone compression and decompression are not real world benchmarks in and of themselves (at least as far as servers go), more and more servers have to perform these tasks as part of a larger role (e.g. database compression, website optimization).
Compression relies a lot on cache, memory latency, and TLB efficiency. This is definitely not the ideal situation for AMD's EPYC CPU. The best AMD CPU has almost 50% more cores than the previous Intel Xeon, but delivers only 11% more performance.
Decompression relies on less common integer instructions (shift, multiply). Intel and AMD cores seems to handle these integer instructions similarly, but AMD's chip has 4 cores more. Fourteen percent more cores result in about 10% faster decompression performance.

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?
