AMD Rome Second Generation EPYC Review: 2x 64-core Benchmarked

While standalone compression and decompression are not real world benchmarks (at least as far as servers go), servers have to perform these tasks as part of a larger role (e.g. database compression, website optimization). With that said, we suggest you take these benchmarks with a large grain of salt, as they are not really important in grand scheme of things. We still use 7zip 9.2, so you can compare with much older results.
Compression on modern cores relies almost solely on cache, memory latency, and TLB efficiency. This is definitely not the ideal situation for AMD's EPYC CPU, but the EPYC 7742 scales very well, offering 77% higher performance than Naples. That is better than expected scaling.
Decompression relies on less common integer instructions (shift, multiply). AMD's Zen2 core handles these instructions even better because doubling the cores results in no less than 127% (!) better performance.
Even though this benchmark is not that important, it is nevertheless impressive how AMD engineering made this graph look. Never have we seen AMD dominating benchmarks by such a wide margin.
Before people accuse us of choosing a benchmark that shows AMD in the best light, consider this benchmark as one of our synthetic tests more than anything else, designed to showcase core execution port potential. It is not really indicative of any real-world performance, but acts as a synthetic for those that have requested this data.

of the '1800 servers', how many of those are virtual, just out of curiosity? ('1800 servers' is not quite as impressive if there were, for example, 10 hosts w/ 180 Windows VMs each, for example) U.S.A.F offices are still mostly Windows 10...I'd suspect the are datacenters at each base having a large Windows Server presence as well.. (But, we used Redhat onboard assorted recce aircraft for many years now....; which seems stupid in light of the fact they could easily use CentOS for free; presumably, a Senator's family members work at Redhat, and enjoy the large income from support contracts)eek2121 - Friday, August 9, 2019 - link
Employers use Windows, data centers use Linux. All the major cloud providers, including Microsoft, have reported that Linux has the highest market share.gylgamesh - Friday, August 9, 2019 - link
Could you please specify what kind of servers those are and what tasks do they perform, and also which MS Windows OS are they using? Thanks.Slickest - Thursday, August 8, 2019 - link
I work for one of the largest colleges in the nation, and 90% of our servers are Windows.69369369 - Thursday, August 8, 2019 - link

Tell your mum you're up late again and she will force you to go outside, and we all know how much your dislike having to do that.prophet001 - Monday, August 12, 2019 - link
I don't get the hate for windows server? How you gonna run a domain and active directory in linux?CaedenV - Wednesday, August 21, 2019 - link
I use to work in schools, and a few that could not afford Windows Server would run AD through some Linux application. It was not exactly full-featured, but it worked well enough for 'free' solution.deltaFx2 - Wednesday, August 7, 2019 - link
@Pancakes: Are you kidding? 1T perf is at par with Skylake. Windows licenses per core. Why would anyone buy a SKU with more cores than they need? And if they did do that, why would they not run them on a VM? Do these people also buy more racks than they need and run windows just for the fun of it?
