Motorola's MPC7457 Soon?

Information on Motorola's MPC7457 PPC Processor emerged in October 2002, when Motorola accidentally posted a PDF on their website.

The basic information from that PDF provided rumor sites with a roadmap to Motorola's 2003 plans with the PowerPC, with a chart describing a MPC7457 with MHz speeds from 867-1833 in 2003. In 2004, a MPC7457-RM chip plans to incorporate RapidIO technology.

A second PDF discussed at Xlr8yourmac provided further information on the 7457 with increase in L2 Cache to 512k and L3 to 4MB.

Yesterday, CubeZone posted a rumor that Powerlogix is planning a 1.4GHz upgrade for the Cube, and according to them, the new product will use a 1.4GHz 7457 G4 from Motorola -- with a 512k L2 and 4M L3.

They note that it may not ship for weeks/months...

The basis of the Powerlogix rumor may have been a G4 cube mailing list post and a reply which downplays this possibility.

At the least, Motorola plans on discussing the 7457 at SNDF 2003 in March.
