Motorola's New PowerPC Chip Hits 733 MHz

Apple's new Power Mac G4 systems will be among the machines running the new processors.

By James Niccolai, IDG News   

Motorola is pushing Macs to higher speeds. On Tuesday, the company launched its new MPC7450 PowerPC microprocessor, designed for a variety of applications including desktop computers, as well as networking equipment and high-end embedded systems.

The processor is shipping now at speeds of 533 MHz, 667 MHz, and 733 MHz, Motorola says in a statement issued Tuesday.

The MPC7450 is the third member of Motorola's G4 (fourth-generation) family of PowerPC chips, and it will be featured in Apple Computer's new Power Mac G4 desktop systems announced earlier Tuesday. The processor is also targeted for use in telecommunications and scientific computing markets, Motorola says.

Customers should benefit from the chip's higher performance, wide data bus, and low-power requirements, Motorola says in the statement.

In particular, the MPC7450 has a deeper, seven-stage pipeline with two additional execution units, and it includes enhancements to Motorola's AltiVec vector processing engine. To further boost performance, the processor's Level 2 cache has been integrated onto the die, and the chip uses a 256-bit data path to the Level 1 cache, Motorola says.

In 10,000-unit quantities, the processors are priced at $250 for the 533-MHz version, $295 for the 667 MHz, and $370 for the 733 MHz, a Motorola spokesperson says.

Also Tuesday, Motorola introduced a speed upgrade to its existing MPC7410 PowerPC processor running at 533 MHz. Pricing for that chip wasn't immediately available.
