90% of the PS2’s floating point throughput is in the two vector units, not the R5900 conducting them. Concentrating on that, as the article does, seems as futile as focussing on the 68000 rather than the Amiga PAD in a 16-bit context (ignoring the EE’s 16-bit RAMBUS bottleneck).

However that approach will probably suit the least-ambitious PC-ports to PS2 (by studios that didn’t appreciate the difference) - rather as an ST emulator was a short cut to run the simplest Amiga games.
