PowerLogix Dual G4 Upgrades

PowerLogix is releasing two new processor upgrade cards:

PowerForce Dual G4 Series 100

PowerForce Dual G4 Series 133

Dual G4-7450 or G4-7455, Speeds up to 1GHz. Speeds range from 800MHz to 1GHz... with faster models available later. The models reflect the bus speed of the machine to be upgraded.

All PowerForce Dual models include 2MB of L3 cache, which is twice what Apple includes on their newest Dual 867 MHz and Dual 1 GHz models. This means an older PowerMac will outperform the latest Apple models, when comparing equivalent clock speeds.

Pricing for the low end model (Dual 800 or Dual 867 depending on the model) is $799.

Pricing for the high end model (Dual 1GHz) is $1199.
