Sonnet Technologies on Monday introduced a new upgrade service to provide faster CPUs for PowerBook G4s originally clocked at 550MHz and 667MHz. The new processor works at 1.2GHz, and the service costs $499.95 plus tax and shipping.

The upgrade replaces the existing CPU in these older PowerBook G4s with a new Freescale 7457 G4 processor equipped with 512KB Level 2 cache running at full processor speed.

Because of the complexity of replacing the CPU with a faster one, Sonnet does the upgrade itself. It’s offering the upgrade to customers in the United States. The CPU is compatible with Mac OS 9.2 through Mac OS X v10.4.x.
