X is justifiably slow (2022)
8 instructions per cycle is a lot, especially on average! I checked and the PPC 970 could fetch, decode, and issue at most 8 ALU ops per cycle, but it could only retire 5 instructions per cycle, so its average IPC is probably less than 4.

8 RISC instructions per cycle is much easier to achieve than CISC ones.
