Motorola pushing for summer 1GHz PowerPC release

Gigahertz Power Macs in same timeframe?

Mac Rumour Roundup Motorola sources suggest the top-end PowerPC 7450 processor will hit 1GHz sooner than previously thought.

The deep throats, cited by MacOS Rumors, claim 800, 866 and 933MHz parts will be rolled out over the next four months or so, culminating in a 1GHz, expected to ship in August.

The Web site reckons all this points to a launch of Power Macs based on all four chips at MacWorld Expo next July in New York, with some boxes shipping then and others following in due course - just as the 667 and 733MHz machines were launched in January.

MacOS Rumors doesn't offer any evidence for this, but we reckon it's not a bad guess given Apple's previous launches.

As for the 1GHz chip, that's certainly where Motorola wants to take the 7540 - aka the G4 Plus. It's what the chip was designed for - to enable such high clock speeds by trading in much of the PowerPC's RISC simplicity. Getting up to 1GHz is feasible, though don't expect volumes to be too high initially. ®
