The HARMONi G3 600 MHz Processor and FireWire Upgrade for iMac from Sonnet is processor upgrade for the first generation iMac computer. The processor replaces the iMac's CPU with a 600 MHz G3 and also adds a 6-Pin FireWire-400 port. This is a great way to breathe new life into your older iMac computer.

Benchmarks with SpeedRun v.120 show that the born-again G3 600 iMac is right there with newer G3 600's and actually faster than a G3 700 iMac, or a G4 800 iMac LCD!

The Bottom Line
We give 5 Thumbs Up to Sonnets HARMONi G3-600 kit

so basically this upgrade gives the imac g3 233/266/333 fruity models a new lease on life, bringing cpu performance to comparable to that of the Powermac G4 800Mhz MP/Dual

they were kind of sneaky to compare the cpu to this machine, because its one of the most underpowered powermac g4's due to its lack of backside cache? i think? or maybe im thinking of the 733mhz model..
anyway  that machine translates to a score of 670 on the primate labs geekbench2 scale, if that is true thats pretty damn good considering the following scores:

209 http://www.everymac.com/systems/apple/imac/specs/imac_dv_400_indigo.html

im not sure i believe that it will make an imac g3 as powerful as a g4 dual 800 quicksilver..
but the data provided in that chart seems to say that..
