Leaked schematics of AMD's upcoming Socket AM5 for Zen 4 Raphael desktop processors indicate that AMD will use the same two-piece retention frame as current AM4 sockets in order to ensure cooler compatibility. Also being leaked is a datasheet that confirms Zen 4 will also see higher TDPs such as 120 W and 170 W with at least a 280 mm AIO cooler recommended for the 170 W TDP SKU.
