Recently we looked at the performance of the AMD EPYC 4545P that is a 16 core 65 Watt processor in the EPYC 4005 “Grado” series. This is quite an interesting processor for those after low-power servers, edge AI deployments, and other purposes with no similar Ryzen 9000 series processor or competition from Intel offering sixteen performance cores at around 65 Watts. Complementing all the performance and power data from that review article, here are some additional tests putting its performance and efficiency compared to the original AMD EPYC 7601 flagship processor that ushered in the EPYC family eight years ago.
With the incredible evolution of the EPYC processor line-up over the past eight years, the original AMD EPYC 7601 flagship with 32 cores / 64 threads (Zen 1) and eight channel DDR4-2666 memory that launched for around $4,200 USD can be easily outdone in performance and power efficiency by the EPYC 4545P in the Grado line-up while retailing for under $600. On a geo mean basis, about to be shown in these tests, the EPYC 4545P can deliver ~2.24x the performance of the EPYC 7601 overall (and even greater gains in cases like AI, HPC, etc) while around half the power consumption and a launch price around 13% that of the EPYC 7601 back in 2017… The AMD EPYC 4005 “Grado” series continues to exhibit a lot of potential for low-cost/affordable web servers and those that may be wishing to replacing aging server infrastructure with new lower-power options while still gaining a hefty performance upgrade.
As a reminder, the AMD EPYC 4545P features 16 Zen 6 cores (32 threads) with a 3.0GHz base clock and 5.4GHz maximum boost clock while having a 64MB L3 cache and a default TDP of 65 Watts. There are 28 lanes of PCI Express 5.0 and dual DDR5-5600 memory support just like the rest of the EPYC 4005 line-up. The EPYC 4545P has a list price of $549 USD while as of writing can be found in-stock at major Internet retailers for around $579.
Recently I ran benchmarks of the Performance & Power Of The Low-Cost EPYC 4005 “Grado” vs. Original EPYC 7601 Zen 1 Flagship CPU (as well as the AMD’s Epic Performance Gains From The Original EPYC 7601 To EPYC 9755 / EPYC 9965 for comparison against the EPYC 9005 Turin family). Now with this interesting 16-core 65-Watt processor, I was curious to see how the EPYC 4545P would hold in this historical comparison to the EPYC 7601 32-core processor with octa-channel memory.
In today’s article is looking at the AMD EPYC 4545P compared to the recent round of AMD EPYC 7601 testing. In addition to the raw performance, the CPU power consumption as well as total server power consumption “wall power” were explored for this historical comparison.
All processors were tested on Ubuntu 25.04 with the Linux 6.14 kernel and using GCC 14.2. Thanks to AMD for providing the EPYC 4545P review sample for Linux testing at Phoronix.
