Apple Unveils Quad-Core Processing with Power Mac G5

Apple on Wednesday unveiled its Power Mac G5 Quad, featuring twin 2.5GHz dual core PowerPC G5 processors at a price of $3,299.


With two 2.5 GHz dual-core processors, each with 1MB of L2 cache, the Power Mac G5 Quad delivers breakthrough performance on applications used extensively by creative professionals and scientists.

Apple said the G5 Quad will come with 250 gigabytes of hard-drive storage and, like the other Power Macs, 512 megabytes of memory that can be expanded up to 16 gigabytes.

"With quad-core processing, a new PCI Express architecture and the fastest workstation card from Nvidia, the new Power Mac G5 Quad is the most powerful system we’ve ever made," Philip Schiller, Apple’s senior vice president of worldwide product marketing, said in a statement.

The new Power Macs will all include a FireWire 800 port, two FireWire 400 ports, four USB 2.0 ports, two USB 1.1 ports, optical and digital audio input and output, and built-in support for 802.11g Wi-Fi and Bluetooth 2.0.

Apple also unveiled a Power Mac with a dual-core 2.0GHz PowerPC G5 processor is available now at £1,399. It includes 512MB of memory, a 160GB hard drive, an Nvidia GeForce 6600 LE video card, three PCI Express expansion slots and a 16x SuperDrive with double-layer support.

The company announced a photo software, called Aperture, as a way for professional photographers to regain tools lost in the move from film cameras to digital technology. The application allows photographers to work easily with thousands of uncompressed RAW files and compare and edit the photos using a digital equivalent of a light table for sorting and a loupe for magnification.


Quad Core is based on the same idea as dual-core, but extending the technology to 4 proccessing cores on one chip.

Quad-core would be a large jump in a computer's ability to multithread, but would cause many other problems. Large amounts of heat would be produced between all four of the processing cores, and both maintaining the processors and the cooling components would create a larger cost to maintain the computer. Not to mention, quad-core would also be largely unsupported by hardware, OSes, and software alike. However, given the speed of the change in the computer market, quad-core may become a common technology in a number of years, as companies constantly search for the next quantum-leap in processing power.
