AMD’s Ryzen 7000 CPUs will feature boost clocks of up to 5.6GHz, at the very least. This bit of info was shared by MLID in his latest video. According to Tom, he’s seen multiple Zen 4 samples hit the 5.6GHz mark and expects at least one SKU to feature max boost clocks around that figure. Getting into the IPC, he believes an uplift of 7-10% is most probable with a multi-threaded performance increase of at least 40%.
Tom also had some new info on Zen 5. The next-to-next-gen core architecture is said to be a major overhaul with a completely redesigned data fabric (IF) and cache. Expect a Zen-Zen 2-like transition where the “Game Cache” and the separate I/O die were introduced. Interestingly, Zen 5 is set to land just 11-15 months after Zen 4 which puts the launch sometime in late 2023, right before Meteor Lake-S.
Zen 5 is also going to feature various Xilinx accelerators to reduce CPU overhead and offload tasks like copying data to a separate IC. At the moment, it’s unclear whether TSMC’s 3nm node will be ready by the time these chips enter mass production. As a precaution, AMD is prepared to go ahead with the N4P process instead.
