From the Merced numbers we can guess that it has 2 extended-precision FMAC
units and 2 single-precision FMAC units (the latter for the exclusive use
of the SIMD instructions).

The Playstation CPU, on the other hand, has 10 FMAC units (probably all but 1
single precision) and 4 FDIV units. What a BEAST! And two RDRAM channels,
so it will almost certainly have greater memory bandwidth than Merced too.

Imagine networking a bunch of these puppies via the Firewire interface
Poor man's supercomputer!

Remember when videogame systems used 10 year old hand-me-down CPUs?
