Reading from the box: CPU, AGP: G4 1.4- 1.53 GHz, Rev.2, Fastmac Motorola G4 7455 Processor - 2MB L3 Cache - Integrated heat sink & fan - Manufacturer says, "6x Faster than Stock G4" ** Easy install, included new firmware which was necessary for my G4 - 450. ** more like 2+ times faster on my 450. I ran photoshop (rotate image) and another cpu intensive application on very large files before installing for comparison. I am pleased with the product, value and speed. Included two quiet fans above the CPU and heat sink. Pretty much plug and play. This is a great forum. Thank you. Jonny
