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.

Hexus got around ≈31,000 iirc.Ryan Smith - Thursday, August 8, 2019 - link
Funny enough, from what I've heard from other people who have tested it, it actually doesn't run all that well with dual EPYCs. Too many cores that are too fast, to the point that initialization times are starting to hold back performance.Ian Cutress - Thursday, August 8, 2019 - link
I got a message from the Cinebench team at one point. They don't spawn/kill/respawn for each little segment: it's kept alive and just fed more data. CB20 is also designed to scale, given that CB15 freaked out above 32 cores or soprisonerX - Wednesday, August 7, 2019 - link
Where is our resident Intel shill? Selling his INTC stock in a panic perhaps?abufrejoval - Wednesday, August 7, 2019 - link

Not gonna lie, I scrolled straight to the comments to see the Intel fanboy spinning this. Instead I got a wall of... Call of Duty references, I think?PeachNCream - Friday, August 9, 2019 - link
The fact that AMD released a product that breaks even HStewart's ability to defend shill for Intel should say something pretty epic about Epyc.Lord of the Bored - Saturday, August 10, 2019 - link
You ain't lyin' there. Seems the name was chosen well.Korguz - Saturday, August 10, 2019 - link
i bet, he would STILL but the intel cpu too. even though it costs more, slower and probably uses more power.Samus - Thursday, August 8, 2019 - link
I was just thinking if Trump doesn't crash the market with his shenanigans then AMD could be an incredibly good buy in the next few months. The first time they've been a good buy in awhile.Although a lot of my daytrader friends have always claimed AMD was a good short-term buy, which is partially true, but if they can keep momentum and Intel doesn't try strongarming them out of OEMs (you know, like they used too...)
