IBM will announce today its first shipment of copper interconnect technology in a 750 PowerPC processor.
The processor uses IBM developed technology to speed connections on the chip using copper rather than conventional aluminium. The new material will increase clock speed from 300MHz using aluminium to 400MHz.
The first machines likely to use the revamped processor will be some Apple Mac models, in new machines and also in upgrade cards.
But other chip manufacturers, including AMD, will also use the copper interconnect process. AMD already has a deal with IBM partner Motorola, which also has access to the technology.
Intel is also working on copper interconnects, but lags behind Big Blue and is unlikely to deploy copper until into the next century.
