Will future AMD EPYCs hit 600W?

Will future AMD EPYCs hit 600W?

According to a rumor, AMD is evaluating a very high configurable Thermal Design Power (cTDP) for its fifth generation EPYC processors. If the information proves accurate, the EPYC 7005 series CPUs, which will be introduced in several years, will be able to feature a 600W cTDP.

On Thursday, well-known hardware blogger ExecutableFix said the AMD EPYC processor " Turin ”in the SP5 form factor will have a maximum cTDP of 600W, which is more than double the cTDP of the latest EPYC“ Milan ”7003 series. The information comes from an unofficial source and cannot be verified, so it should be taken as mere rumors. Still, there is a logic behind this information.

Fifth generation AMD EPYC processors are said to have up to 256 Zen 5 cores. It also appears that AMD is preparing hybrid processors with integrated CDNA-based compute GPUs for HPC (High Performance Computing) and datacenter applications. CPUs with up to 256 "fat" cores are ready to consume a lot of power, even if a 600W cTDP seems a bit high.

In addition, cooling system manufacturers already have 400W capacity for AMD EPYC 4th generation “Genoa” processors (which use the SP5 infrastructure) in their catalog, so it is clear that AMD's next generation server platforms they are designed to support rather power-hungry CPUs.

Today's hyperscale cloud data center operators and businesses with demanding workloads want to have the highest possible performance; therefore, AMD and Intel must offer them CPUs with unbeatable performance that often feature a high TDP. In fact, the TDP of server processors has been growing rapidly for nearly a decade, so it won't come as a surprise to see next-generation processors consume more power than existing ones.

Server-level platforms are not thought of. only to support standard CPUs, but also various custom versions optimized for certain workloads which may result in a higher TDP. Therefore, while special versions of next-generation AMD EPYC processors may have TDPs of up to 600W, regular models will be more limited.
