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.

on-prem Windows Server is probably at an all time high in 2019?azfacea - Thursday, August 8, 2019 - link
desperate for a comeback huh? cool hold your 10% tight and gloat about upcoming bfloat16diehardmacfan - Thursday, August 8, 2019 - link
Sorry, who is desperate for a comeback? Bring up a floating point format when called out on the ridiculous notion that Windows Server isn't still a large part of the marketplace? say whamkaibear - Thursday, August 8, 2019 - link
Just hopping in to say that I am an IT manager for a major employer in the UK and of our 1800 servers more than 80% of them are Windows... this is not a trend which I see changing any time soon.Deshi! - Thursday, August 8, 2019 - link
I work as an application engineer for a major global finance company that develops and hosts banking and e-commerce software used by banks and major shopping outlets. 90% of all our servers are either Linux or AIX mainly running websphere or standalone Java instances. We only have a handful of Windows servers, mainly for stuff like active directory and Outlook/ SharePoint. So yeah allot of it depends on the use case, but allot of the big boys do use Linux or AIX. It's cheaper and performs better for these use cases.cyberguyz - Thursday, August 8, 2019 - link
I guess we all have to ask ourselves, who are the customers that would benefit most from a 64-core, 128 gen 4 PCIe processors? SMB or huge customers that would shell out many millions of $$$ for their middleware & backend systems? @Deshi! I or one of my L3 colleagues an L3 engineer contacted by your global finance company to fix Websphere problems some years back ;)FreckledTrout - Thursday, August 8, 2019 - link
@cyberguz, Who would benefit from these high core servers? Any company running VM's so pretty much every large company. This goes doubly for cloud providers.
