This is impressive since Renoir's GPU is still on GCN design, but the CPUs are vastly improved for sure. 28nm -> 14nm -> 12nm -> 7nm node shifts, even though there are only three major nodes here, since GF 14 and 12 are not really different 'nodes'.
Anyway, this is awesome to see and showcases how much AMD has turned around what was a failing CPU design into the most efficient and scalable x86 CPU architecture available, right now, on Planet Earth.
So, that's a good job done for everyone at AMD. Awesome to see.
