A number of STH readers pointed us to AMD’s product pages where they have added new AMD EPYC 7003 “Milan” SKUs. These are fun as they generally fall into two categories: new single socket “P” SKUs and low-power SKUs. We figured we would at least give them a quick mention as they appear to be a transition from the “Rome” parts that used to occupy these segments.
AMD Adds New Low Power AMD EPYC 7003 SKUs
Here is the quick SKU list for the new parts:
The AMD EPYC 7663P and EPYC 7643P are single socket parts at different core counts than were released at launch. 56 cores is interesting since it is the same core count as the practical maximum for the Intel Xeon Sapphire Rapids parts. 60-core Sapphire Rapids are not high-volume parts which is why we see things like the Intel Xeon MAX 9480 as a 56-core not a 60-core part. AMD is matching the 56 cores which is either one Sapphire Rapids Xeon or two Cascade Lake Xeons in a single socket.
The much more interesting parts are going to be the AMD EPYC 7303P and EPYC 7303 16 core parts. These two are only around $37 per core and have 130W TDPs. That is a lower power level than we typically had seen with the Milan series.
In that same vein, with 8 cores we have 7203P and the EPYC 7203. These are the low-power 120W 8-core parts.
Both the 8-core and 16-core parts do not really have a notable discount for the “P” parts, so it feels almost unnecessary. At the same time, they are very necessary. AMD needed to replace the AMD EPYC 7232P and other low-power parts. Until now, the low-power and low-cost socket SP3 option had been to go back to the AMD EPYC 7002 series CPUs. Now, there is an EPYC 7003 option.
The AMD EPYC 7303(P) might be the standout in this new set of CPUs. The CPU still has a lot of I/O for PCIe with 128x PCIe Gen4 lanes, but also is a lower power part. 120W is lower than many desktop CPUs. For those who just want to have decent CPU performance, having 16 Milan cores is going to be plenty, and having lots of PCIe Gen4 can be very exciting indeed. Intel’s least expensive Sapphire Rapids 16-core part is the $944 Intel Xeon Gole 5416S. In the Ice Lake Generation, Intel has the Intel Xeon Silver 4314 at a 135W TDP and a $694 list price. AMD is undercutting the TDP and pricing of Intel’s nearest PCIe Gen4 competitor while offering more PCIe connectivity, important in this segment.
For those wondering why we get new processors after the AMD EPYC Genoa and AMD EPYC Genoa-X/ Bergamo launches is simple. PCIe Gen4 is still very popular for applications like storage and Genoa TDP/ pricing is much higher. We are going to see PCIe Gen4 platform continue for some time as a lower cost option to today’s higher-end servers.
