This comment is misleading. Z80 also has an 8-bit external bus. And, FWIW, so does the 6502. The reason zero page is fast on the 6502 is because of more concise encoding, not because that memory is somehow faster.
I'm broadly skeptical that a 6502 outperforms an 8088 at 5x clock speed in practice. Would love to see benchmarks. Certainly I'd expect it to be highly task dependent.
