PowerPC 7445 and 7455

The PowerPC 7455 "Apollo 6" was introduced in January 2002. It came with a wider, 256-bit on-chip cache path, and was fabricated in Motorola's 0.18 µm Micrometre or 180 Nanometers HiPerMOS process with copper interconnects and SOI. It was the first processor in an Apple computer to pass the 1 GHz mark. The 7445 is the same chip without the L3 cache interface. The 7455 is used in the AmigaOne XE G4, and the dual 1 GHz Power Mac G4 (Quicksilver 2002)
