I would expect that VPC on a 200 MHz PPC 604 SHOULD be about equivalent to
a 100 MHz Pentium (this assumes linear speed benefits to vpc with
increases in PPC speed AND assuming that a 150 MHz 604 on vpc is
equivalent to a 75 MHz P5).  I would also expect that to get about the
performance of a 133 MHz P5 you would need a 266 MHz PPC.  Anyone with
something along this line able to confirm the speeds?  Perhaps by running
the Quake timedemo benchmark?  Also, I BELIEVE there is a means in Duke
Nukem 3D to get a framerate indication onscreen.  It isn't as clean as the
timedemo method of Quake but it would give an indication of what is being
seen.  With a 133 MHz P5-performing VPC you would essentially be able to
run all PC game software at decent and playable speeds...with Quake being
somewhat of an anomaly due to the fpu usage.
