the slow system bus and memory of the Mac G4 systems would be the bottle neck keeping a quad G4 upgrade from performing like it could, but it would still be awesome to have and see what its limits can be. cause i would think even on a slow system /memory bus it would still result in a nice performance gain.

but that is IF this was ever made for a Mac system. it would cost a arm and a leg to buy one if a upgrade was ever made for G4 Mac's .

i would love to see what a G4 CPU would do with 128k L1 cache (64 instruction/64k data) , 1MB L2 cache , and 2MB L3 cache. i would love to see if it would increase the performance or decrease it in any way. wouldn't you think that by lowering the L1 cache to 32k (16K I/16K D) that it would drop in performance vs a cpu with 64k L1 ( 32K I/32K D). the link shows that CPU has only 32k total L1 cache, or did i get the wrong ideal on how its stated.

i would love to see a quad G4 cpu upgrade available for Mac. but the price for one would be insanely high. and see who would fork over that much to buy one.
