During the announcement of the Ryzen 7000 processors, AMD showed a slide stating that the respective AM5 platform natively supports up to 170 watts. However, what exactly is meant by this number has not been clarified until now. Meanwhile, the red team gave Tom’s Hardware’s Paul Alcorn more information.
For example, AMD announced that the AM5 processor leg has Packet Power Monitoring of up to 170 W. This is 28 watts more than the 142 W maximum for AM4 processors with 105 W tdp. This peak value is higher than tdp, so the latter will practically be less than 170 W for Zen 4 based chips. .
As usual, AMD uses a PPT ratio of 1.35 compared to TDP. So in theory, the most powerful Ryzen 7000 SKUs can get a TDP rating of around 125W, or about 20% more than their predecessors. However, there is no guarantee that this will be the case in this generation.
This extra boost can help boost clock speeds: Ghostwire: During a demonstration in Tokyo, an overlay shows that an unknown sku can be boosted to less than 5.52 GHz. Also, the 16-head Ryzen 7000 processor claims to perform up to 31% faster in Blender compared to the Intel Core i9-12900K (16c/24t).

AMD has informed Tom’s Hardware that the aforementioned 170 W actually refers to tdp rather than ppt. This means that the AM5 socket has a Packet Power Monitor of 230 watts, an increase of 62% compared to the most powerful AM4 chips (142 W). AMD’s Robert Hallock confirmed on Reddit that there are actually Ryzen 7000 skus handling this tdp.
According to Hallock, the Ryzen 7000 hexadecacore on display at Ghostwire: Tokyo has a TDP of less than 170W, achieving an all-core boost clock of 5 to 5.5GHz.
