CPU Performance: Rendering and Synthetics
For the rest of our CPU tests, we’re using a mix of rendering and synthetic workloads. This is slightly different to our previous server reviews, due to some adjustments, and we hope to be running something similar to our standard server workloads in the near future.
All CPUs are run with SMT/HT enabled.
Even with the addition of a socket-to-socket in the mix, the dual 7F52 setup scores up to +100% in some benchmarks over the previous generation EPYC 7601. Against Intel’s latest 16-core Cascade Lake Refresh hardware, the AMD takes a sizeable lead in most benchmarks (except notably AVX512), which is perhaps to be expected given the price difference and power difference. What is interesting is how in certain workloads, the 2P 7F52 setup can make a reach up for the Xeon 8280s, despite the 8280s being 3x the cost each.

Expecting EPYC F7U12.efferz - Wednesday, April 15, 2020 - link
the IPC of 9900KS is 1.56/G while the 6226R is 1.05/G？AntonErtl - Thursday, April 16, 2020 - link
Why buy an EPYC 7F52 rather than some other AMD CPU?Compared to a Ryzen 9 3950X? You need more than 128GB RAM, more than 4MB cache/core or more DRAM bandwidth; as for clock, they have the same base clock, and the 3950X has quite a bit more max clock.
Compared to a Threadripper 3960X (and not use, maybe deactivate 8 cores)? You need more then 256GB RAM, more than 8MB cache per core, or more RAM bandwidth; clockwise, the Threadripper is better in every way.
Compared to another Rome EPYC? You want 256MB cache, but want to pay less than for a 7642 or a 7702P; or you want a higher clock rate than other 16-core EPYCs offer.
This all seems quite specialized to me; I guess there are some supercomputing or database applications that benefit from high DRAM capacity and bandwidth and big caches; but if an application is DRAM-limited, it usually does not need high clocks (waiting for memory at a higher clock rate does not make the DRAM access significantly faster).
As for benchmarks, I guess Stream will show up the RAM bandwidth, but there it will perform like any other Rome EPYC.

Ok, so how successful was the 7371?eastcoast_pete - Monday, April 20, 2020 - link
@Ian (Dr. Cutress): Again, appreciate your reviews! Question: Could you do a review of a Ryzen on the exact opposite end of the price scale, namely the Ryzen 3 1200? It is now Zen+, fabbed in GloFo's 12 nm LP process, and around or under $ 50. Not bad for 4 cores, especially if you have a dGPU and a compatible board at hand. Just make sure to update the BIOS as needed before installing the CPU.dwade123 - Tuesday, April 21, 2020 - link
Overpriced junk
