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.

It's been a pretty good investment for me, bought at 8$ two years ago, seems like I'll keep it for a while longer.CheapSushi - Wednesday, August 7, 2019 - link
It's glorious...one might say.... even EPYC.abufrejoval - Wednesday, August 7, 2019 - link
Hard to believe a 64 core CPU can be had for the price of a used middle class car or the price of four GTX 2080ti.Of course once you add 2TB of RAM and as many PCIe 4 SSDs as those lanes will feed, it no longer feels that affordable.
There is a lot of clouds still running ancient Sandy/Ivy Bridge and Haswell CPUs: I guess replacing those will eat quite a lot of chips.
And to think that it's the very same 8-core part that powers the engire range: That stroke of simplicity and genius took so many years of planning ahead and staying on track during times when AMD was really not doing well. Almost makes you believe that corporations owned by share holders can actually sometimes actually execute a strategy, without Facebook type voting rights.
Raising my coffee mug in a salute!

Sandy Bridge maxed out at 8c/16t.Ivy Bridge maxed out at 15c/30t.
Haswell maxed out at 18c/36t.
That means that a single socket Epyc 64c/128t can give you more CPU cores than a quad socket Sandy Bridge (32c/64t) or Ivy Bridge (60c/120t) and only a few less cores that a quad socket Haswell (72c/144t).

This is what we've all been waiting for!Eris_Floralia - Wednesday, August 7, 2019 - link
Thank you for all the work!quorm - Wednesday, August 7, 2019 - link
Given the range of configurations and prices here, I don't see much room for threadripper. Maybe 16 - 32 cores with higher clock speeds? Really wondering what a new threadripper can bring to the table.willis936 - Wednesday, August 7, 2019 - link
A reduced feature set and lower prices, namely.quorm - Wednesday, August 7, 2019 - link
Reduced in what way, though? I'm assuming threadripper will be 4 chiplets, 64 pcie lanes, single socket only. All ryzen support ecc.So, what can it offer? At 32 cores, 8 channel memory becomes useful for a lot of workloads. Seems like a lot of professionals would just choose epyc this time. On the other end, I don't think any gamers need more than a 3900x/3950x. Is threadripper just going to be for bragging rights?

Sorry, forgot to add, 3950x is $750, epyc 7302p is $825. Where is threadripper going to fit?
