No, RISC is faster *ever* but eats up more memory.

My G3/233 can render SKYVASE.POV at 640*480 with antialiasing (the
classical povbench options) in 00:02:31 while a PII/233 in 00:03:18.

40% faster.

I noticed that Level II cache speeds up raytracing dramatically.

On my old 4400/200 (PowerPC 603e) I discovered that with 512k cache
it rendered twice as fast than without cache.

Obviously the bigger the cache, the faster the render (except, I think
if all the parsed object will fit in the cache, in this case I think
that an even larger cache won't help much).

I noticed that PentiumPro renders very fast and I think this is due to
his extremly fast 1:1 level II cache (running at the same processor
speed).

Just my opinion
