AMD EPYC 4545P: 16 Zen 5 Cores @ 65 Watts For Low-Power / Energy Efficient Servers
First up for testing was evaluating the code compilation performance of these low-cost EPYC processors up against the Xeon 6300 series. The EPYC 4545P with its 16 cores while having a default 65 Watt TDP understandably comes out slightly behind the EPYC 4585PX and EPYC 4565P for those 16-core 170 Watt parts. Similarly, the 16-core 120 Watt EPYC 4584PX and 170 Watt EPYC 4564P processors were slightly faster too, but just by three seconds for carrying out a default Linux x86_64 kernel build.
When factoring in the real-time CPU power consumption during each respective benchmark, the EPYC 4545P easily shines for delivering the best performance per Watt. In the case of building the Linux kernel with all possible x86_64 kernel modules the average power consumption was at 85 Watts, similar to that of the other 65 Watt processors tested like the EPYC 434P and EPYC 4464P. The EPYC 4545P was delivering over twice the performance per Watt of the Xeon 6369P flagship competition. With a list price of $549 USD, the value was also comparable to the other EPYC 4005 processors -- significantly better than the Xeon 6369P.
With other code compilation workloads the story remained the same for the EPYC 4545P: the performance was comparable or slightly slower than the 16-core EPYC 4004 processors but when factoring in the 65 Watt TDP it's a home-run for those concerned about power efficiency... 16 Zen 5 cores at a 65 Watt TDP (or commonly around 85 Watt during the code compilation tests) yielded by far the best performance-per-Watt of the tested processors. For those having an always-on CI/CD build box or otherwise having a server tasked with frequently compiling code and similar tasks, the EPYC 4545P can serve as a very power efficiency solution especially for cost conscious developers and small organizations. The value of the EPYC 4005 series continues to far outpace anything currently provided by the Intel Xeon 6300 line-up.
