Motorola's new PowerPC chip reaches 733MHz

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

The MPC7450 is the third member of Motorola's G4 (fourth generation) family of PowerPC chips, and will be featured in Apple's new Power Mac G4 desktop systems announced earlier Tuesday. The processor is also targeted for use in telecommunications and scientific computing markets, Motorola said. Customers should benefit from the chip's higher performance, wide data bus and low-power requirements, Motorola said in the statement.

In particular, the MPC7450 has a deeper, seven-stage pipeline with two additional execution units, and 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 said.

Designed at Motorola's Austin, Texas technology centre, the MPC7450 is being manufactured using a HiPerMOS 6 (HiP6) 0.18-micron copper fabrication process technology, Motorola said. In 10,000-unit quantities, the processors are priced at $US250 for the 533MHz version, $US295 for the 667MHz, and $370 for the 733MHz, a Motorola spokesman said.

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

Brother QL-820NWB Professional Label Printer

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
