"She's my little deuce coupe.
You don't know what I got."
(Hopped up Power Mac 7500 surprises a G4/400 Yikes!)

My old Power Mac 7500 has been modified more times than a deuce coupe. I couldn't resist trying to tweak it just once more to try running with the new, hot G4's. I had to cheat a little this time, though. I'll tell you how after I amaze you with the results:
Now, these next two charts show what the Velocity Engine does on the Yikes:
Conclusion: The 7500/G3 "deuce coupe" won 6 out of the 10 "races" and was a close second in the rest (with AltiVec disabled).
Comments: Okay, I cheated. I ran a highly modified 7500 against a "stock" G4/400. The 7500 had a ProFormance3 graphics accelerator (instead of a RAGE 128 board like the Yikes), 3:2 cache ratio (instead of 2:1), MathLibMoto, and a faster IDE hard drive.
But the Yikes has its own advantages: 100MHz bus (versus 50MHz), 66MHz PCI slot (versus 33MHz), fast memory (8ns vs 60ns), G4 (vs G3), etc.
The bottom line is that if you love your old PCI Power Mac too much to let it go, you can squeeze some impressive speed out of it. Just wait until I get a G4 upgrade and an Evil Eye Voodoo3 board!
Of course, nostalgia costs you. These upgrades to the 7500 are not cheap. If you added all the mods I used, it would cost you over $1200... most of the cash you need for a G4/400 Yikes!
