Motorola, The G4 and PowerBook Updates

The Register provides some insight and rumors into upcoming G4 processors from Motorola. According to their article, MPC7457 processors from Motorola are arriving sooner than expected:

While originally slated for Q4 2003, according to Synergy Microsystems (a Motorola customer):


    Final 7457 boards will ship in Q3, says Synergy, "when production quantities of the [7457] become available".

The new chip from Motorola (announced in February) increases the L2 cache as well as the L3 cache and provides a max speed of 1.3GHz -- and incorporates a 200MHz frontside bus, allowing for DDR400 support.

The Register expects this chip to be the most likely processor for the upcoming PowerBook.

This is consistent with one unverified rumor that upcoming PowerBooks come in at 1.3GHz.
