The PC Engine CPU is highly underrated. People like to go "haha, it was the TurboGrafx-16 but its CPU was 8-bit" like that makes it a joke, but that clock speed boost on top of the 6502 architecture is a big deal. (The S-CPU on the SNES still has an 8-bit data bus too, so the 16-bit advantage isn't as strong as it seems)
The Arcade Card add-on was designed specifically around using the transfer instructions to rapidly transfer graphics into VRAM, something it was very good at. Made some really good Neo Geo ports possible.
