Apple Computer Inc. Monday officially confirmed what has long been rumored: the company will use IBM Microelectronics' PowerPC G5 processor for what is claimed to be the market's first 64-bit desktop computer.
Apple introduced the Power Mac G5, which CEO Steve Jobs said is the fastest 64-bit desktop at 2GHz clock speed.
The IBM PowerPC G5 uses a 1GHz interface to deliver bandwidth at up to 8Gbytes/s. Apple designed the systems controller for its computer, which includes a HyperTransport interface running at 800MHz, a 128-bit DDR memory interface at 400MHz, and an AGP 8X Pro graphics interface.
The PowerPC G5 allows the new Apple desktop to have 64-bit computing capability, while at the same time running 32-bit application software in native mode. The MPU is built in IBM's new 300mm wafer fab in East Fishkill, N.Y. using 0.13-micron processing and silicon-on-insulator technology. The chip has 58 million transistors.
