minus-squareJustin@lemmy.jlh.namelinkfedilinkEnglisharrow-up8·edit-211 个月前I believe both M2 and Zen 5 use 4nm. 4nm is just a slightly improved 5nm, though. It’s the same process node, not an entirely new process node like 3nm.

N4 and N4P are usually called 4nm in marketing material. There’s probably a leaker out there with more knowledge.
