AMD EPYC 7351P Linux Performance: 16 Core / 32 Thread Server CPU For ~$750
Written by Michael Larabel in Processors on 19 October 2017. Page 7 of 7. 54 Comments

The EPYC 7351P with the Tyan Transport SX TN70A-B8026 yielded a minimum power draw of 96 Watts while the average under load was 163 Watts while the peak AC power use by this system was 230 Watts.

On a performance-per-dollar basis, the EPYC 7351P was leading overall among the Intel/AMD processors available for testing. The significant value of the EPYC 7351P doesn't come as too much of a surprise as for just 1.5x the cost of the EPYC 7251, the EPYC 7351P has twice the number of cores / threads, that also means twice the L3 cache size, higher base clock frequency, and DDR4-2666 rather than DDR4-2444. The important reminder though with the "P" EPYC processors is that they are limited to single socket systems unlike the non-P models where you can assemble a dual socket system now or down the road.

If you are building a single socket server/workstation, the EPYC 7351P is a worthy competitor to consider if looking to spend under $1000 USD and will be leveraging mostly highly threaded workloads. With these benchmarks it was incredible to see the number of tests where the EPYC 7351P could compete with -- or in some cases even outperform -- the Xeon Gold 6138 that costs about three times as much money.

Thanks to the design of the Phoronix Test Suite and for ensuring reproducible, fully-automated, open-source Linux benchmarking, it's very easy to see how your own Linux system(s) would compare to these results. With the Phoronix Test Suite installed, simply run phoronix-test-suite benchmark 1710193-AL-EPYC7351P64 for your own fully-automated, side-by-side comparison against the Linux CPU performance benchmark results found in this article.
