Freescale (Motorola) announce new G4 CPUs
Press release
EETimes coverage
Tech specs
Yesterday, Freescale (formerly Motorola SPS) announced a new PowerPC G4 processor, the MPC8641D. It's a dual-core CPU with an onboard DDR/DDR2 memory controller running at up to 667MHz, a vast improvement over the current performance crippling 167MHz. There's also 1Mb of L2 cache per core.
This could be a nice chip for a revised PowerBook, as the G5 doesn't look like it's heading into a 1" thin enclosure any time soon. The on-die memory controller also means one less chip on the motherboard, so it should improve cost and battery life.
They also announced the MPC7448. The 7448 is the successor to the current MPC7447 currently used in the PowerBook and iBook and is a drop in replacement, with FSB speed up to 200MHz from 167MHz. I see this chip heading for the iBook G4 line, which would be a nice bump.
Clock speeds for both parts are given as 1.5GHz up, fabbed at 0.9nm.
