Be aware that the Sony Emotion Engine chip, under Linux, runs the POVRay
benchmark image (skyvase.pov) about 5 times faster than a 933 MHz
Pentium III, so that probably means that it's over 10 times faster than
your 433 MHz PII.

Sony are currently developing a workstation that runs a number (I don't
know how many) of Emotion Engine chips in parallel. Theoretically, such
a machine with 128 such chips would be capable of rendering scenes
nearly as complex as skyvase at 30 fps.

Such a workstation will be quite expensive when it first comes out, but
in a decade or two we'll have home computers that are this fast.
