  *bzzzzt*  Thank you for playing.

  You've forgotten about the performance of the processor, and the
number of processors.  A Cray T932/32 can deliver a sustained 64GFLOPS
of big-testicle 64-bit floating-point power.  You point me to a
workstation that can do that, and I'll eat cat food in order to buy

  ...and, well, vector execution units.  And multiple processors.  And a
crossbar switch for memory access.  And multiple I/O processors.  And
the fact that the Cray PVP architecture isn't very RISC-like.
