AMD EPYC 4545P Achieves 2.24x The Performance At Half The Power Of The First EPYC CPU
Those interested can find more than 230 benchmarks in full from this comparison across dozens of different workloads/use-cases.
On a geometric mean basis, the EPYC 4545P was at 2.24x the raw performance of the EPYC 7601. All the more impressive when considering the EPYC 4545P is at half the cores/threads and using dual channel memory as opposed to eight memory channels. And with a 65 Watt TDP compared to a 180 Watt TDP.
The power efficiency story of the EPYC 4545P makes this a uniquely positioned server processor for low-cost web servers, low-power AI edge nodes, other budget server uses, or if wanting to replace aging EPYC Naples era infrastructure with something much more power efficiency while still delivering greater performance capabilities. That 2.24x performance was achieved while the CPO power was at 51% that of the EPYC 7601. The peak CPU power difference of the EPYC 4545P was at 45% that of the EPYC 7601.
On a system power consumption basis, the EPYC 4545P had a 117 Watt average for this Supermicro server compared to a 238 Watt average with the Tyan EPYC Naples server. The peak "wall power" of this comparison was 148 Watts with the EPYC 4545P Grado server and 382 Watts with the 1st Gen EPYC server. Quite the power savings with the EPYC 4545P-based server while still outperforming the original AMD EPYC flagship processor.
This also shows how the AMD EPYC 4005 processors for value-oriented servers is also a much better bargain for performance and efficiency than pursuing a larger, used server platform from the early days of EPYC. Going for a brand new EPYC 4005 series server rather than a used EPYC Naples or even Rome server can deliver better performance and much better power efficiency and in turn TCO than a used/re-purposed server that may have more cores and greater number of memory channels as shown by these benchmarks.
As noted in the AMD EPYC Naples to Turin comparison there can be really extreme performance upgrades if moving to the EPYC 9005 series but for those most concerned about power efficiency and TCO, the EPYC 4545P is uniquely positioned to deliver great budget server performance with the lowest possible power use. And the EPYC 4545P retails for less than $600 and still better than Intel's flagship Xeon 6369P 8-core flagship processor that has a 95 Watt TDP...
