Zen 4: AMD clarifies the 170 watt TDP in Ryzen 7000 – again
The saga of the 170 watt TDP in Ryzen 7000 is not over yet: AMD has now clarified once again and confirmed that 170 watts is actually the TDP. It follows that the PPT is 230 watts.
Zen 4’s TDP and PPT cause some confusion though. Initially, shortly after the presentation, it was agreed that it was 170 watts PPT and, as a result, probably 125 watts TDP. However, there were different statements in the documents and a query to AMD did not initially provide the correct answer. However, as it turns out, the US press materials and information from MSI are correct.
AMD’s EMEA marketing has clarified today that the Zen 4 is indeed 170 watts TDP (Thermal Design Power). In conclusion, Ryzen 7000 has a PPT (Package Power Tracking) of 230 watts (170 x 1.35 = 229.5). That is considerably more than the currently sold generation. But you also know that the larger models in particular quickly reach their artificial limits. AMD has now opened them up far enough that they should no longer be a problem.
Traditionally, you always have to go the extra mile for the last few MHz. In order to get Ryzen 7000 to over 5 GHz boost, it seems that space has to be created despite 5 nm production. It would be assumed that the large models with 12 and 16 cores in particular would otherwise have had to be slowed down too much and come with a TDP of 170 watts. 65 and 105 watts remain in the program. The IGP, presumably clocked at 256 shaders and 1.1 GHz, shouldn’t really matter much and should usually be deactivated.
AMD in the original wording:
“AMD would like to issue a correction to the socket power and TDP limits of the upcoming AMD Socket AM5. AMD Socket AM5 supports up to a 170W TDP with a PPT up to 230W. TDP*1.35 is the standard calculation for TDP v. PPT for AMD sockets in the “Zen” era, and the new 170W TDP group is no exception (170*1.35=229.5).
This new TDP group will enable considerably more compute performance for high core count CPUs in heavy compute workloads, which will sit alongside the 65W and 105W TDP groups that Ryzen is known for today. AMD takes great pride in providing the enthusiast community with transparent and forthright product capabilities, and we want to take this opportunity to apologize for our error and any subsequent confusion we may have caused on this topic.”
