AMD is rumored to be looking for a very high maximum configurable thermal design power (cTDP) for its generation 5 EPYC processors. If the information is correct, the AMD EPYC 7005 series CPU, scheduled for launch in a few years' time, may have 600W of cTDP.

Hardware blogger ExecutableFix gave them accurate information on Thursday, saying that AMD's SP5-shaped EPYC 'Turin' processor has a maximum cTDP of 600W, more than doubling the 7003 series "Milan" processor compared with the latest EPYC cTDP. This information comes from unofficial sources, is not detailed and cannot be verified, so please have reservations. However, there is a basic principle behind this information.

It is rumored that the AMD fifth-generation EPYC processor in SP5 form factor has up to 256 Zen 5 cores. It is rumored that AMD is also preparing to integrate hybrid processors of CDNA-based computing GPU for high-performance computing (HPC) and data center applications. Although 600W cTDP may seem a bit high, CPU with as many as 256 "fat" cores consumes a lot of power.

According to gigabyte leaks, AMD's SP5 platform for fourth-and fifth-generation EPYC processors is designed to provide up to 700W in a very short period of time, so 600W cTDP is likely to be correct. At the same time, radiator manufacturers have listed 400W cooling systems for AMD's fourth-generation EPYC 'Genoa' processors (using SP5 infrastructure), so it is clear that AMD's next-generation server platform is designed to support power-consuming CPU.

Today, operators of very large cloud data centers and enterprises with demanding workloads want the maximum performance they can get, so AMD and Intel must provide them with CPU with unparalleled performance, which usually has a high TDP. In fact, the TDP of server processors has been growing rapidly for about a decade, so it's not surprising if the next-generation server CPU consumes more power than the existing server CPU. At the same time, sometimes AMD and Intel have to provide specific customers with customized CPU that consumes more than regular models.

Server-level platforms should support not only standard processors, but also various custom versions optimized for certain workloads that may have higher TDP. So while it is true that a special version of AMD's next-generation EPYC processor can upgrade itself to 600W, the TDP of a regular SKU may be much lower. That is, although some of AMD's future EPYC processors may have 600W cTDP, it is too early to assume the TDP level of the standard CPU.
