They are currently the only update cards to use the latest technology available from Motorola, the "Apollo" G4 / 7455 processor. Interesting that not only Apple's desktop towers but also the "defunct" Cube that will find will benefit new life from a doubling and more of the processor frequency.
The Apollo has four integer execution units, a dual precision FPU and 4 128 Bit Altivec units. It also has a level 1 cache on chip at the same speed as the processor. PowerForce G4, this is the name of the cards, will be available with several level 3 cache cuts.
PowerForce G4 processor upgrade simply replaces the original processor board in a few minutes and the operation can be performed directly by the user.
