- We use some iris4d 35 (R3000, 30Mhz) and some PC compatible (with
- DELL-Unix) with an intel 486/33Mhz. In general, the R3000 (cc with
- option -O2) have
- 170-190 % of the speed of the intel processor (by excessive using
- of floating point operations). If you use the gcc compiler for the 486
- with option -O2 instead of the DELL cc compiler (haves only option -O)
- the code becomes 10 % faster (R3000 : 486 = 1.6-1.8 : 1).
-
- The graphic on the PC (with VGA board) is much slower and by excessive using it
- slows down the whole PC.

- R3000:
- 1 30 MHZ IP12 Processor
