Here is a tidbit for those who keep thinking the Gekko or Broadway is just another G3. I grabbed this quote from the ign boards after someone posted a link on the cpu saying it's a lot more power than what people think.
"To clear things up: the top-of-the-line PPC 750, the 750GX, is the fastest 7xxx PowerPC. It's much faster than Apple's G4 (PPC 744x) at the same frequency. To call it an overclocked G3 would be quite an understatement. IBM's current 750-series PPCs even outperform G5s at the same clock speed, but don't feature 64bit integer processing. The 7xx series still is the mainline PowerPC family, the 8xxx series are special, embedded 7xx chips, and the 970 chips are nothing more than cheap POWER4 spinoffs, initially created for Apple (IBM prefers POWER4 and POWER5 over PPC970 for their own systems). And no, Gekko was no G3, it's only part of the same CPU family. But Gekko, aka PPC 750CXe, had SIMD units similar to Altivec/ VMX, the G3 only had a regular FPU."
