According to MacOSRumors.com (which is not always correct) ...
"On Wednesday, MPC 8500 revision 0.6 was received. This revision fixes a cache bug, and has improved altivec peformance to 85% of the 7460 G4's at equal Mhz that are now in production. This is up a whole 50%. There have also been some minor changes with changing the positioning of the L1 and L2 cache on the die. The majority of G5's in this lot that functioned ran at 1Ghz, 1.2Ghz, and 1.4Ghz, with a considerable number running at 1.6Ghz, and 2 chips tested at 2.4Ghz! The goal is to bump this up one step before release, which there is confidence in happening.
. . . The 7460 G4's are now in volume production, and Motorola has enough available to give the G4 another speed bump as we speak in speeds up to 1.33 Ghz, but Apple does not want to do this because it just released an updated G4 lineup, and it does not want to have excess inventory of Power Mac G4's on hand if it can start offering the Power Mac G5 early next year. This means that Motorola will have to carry this 7460 inventory until Apple releases the next generation Powerbook G4 at Macworld Tokyo. This powerbook will essentially be the same as the 667Mhz model except that it will sport the 7460 G4 which has lower power consumption than the 7440."
Also. . .
"One feature of the Book E architecture is certainly going to make Virtual PC users happy. An alpha version of an upcoming release of Virtual PC provides 1GHZ PIII performance on a G5 running at 1.4GHZ. "
We'll see . . .
