Dallas, TX announce the IBM 970 Alitivec compatible is to be the new PowerPC processor, but it will only have a single core. No multi-core as previously rumored.

IBM has presented the new PowerPC. It's a watered-down, only-one-core version of the Power4. It adds the Altivec vector unit and with the reduced die size it becomes affordable and attractive to Apple.

It's not official that Apple is a customer though.

The new 64-bit PowerPC is a 64 bit machine that runs the 32-bit code natively, on the same pipeline as the 64-bit core.

We've been reminded that the PowerPC specification is originally 64-bit, but contemplates a 32-bit version. There have been two previous 64-bit PowerPCs that flopped.

The new PowerPC triples the pipeline length to achieve higher frequencies of 1.4 to 1.8 GHz in the 2nd half of 2003. We'll see at what frequencies Intel and AMD are running by then.

Yes, very few things can live up to the hyped up expectations of the rumormill. When you consider the added instruction dispatch, out of order execution, 2nd altivec compatible unit, larger cache, increased bandwidth due to being 64-bit, increased addressing space, and what appears to be DDR support (450mhz doubles to 900 bit) this chip is awesome.
