Apple goes Duel-Core

What appears to be the last major upgrade to the power mac line before Apples switch over to Intel CPUs from IBM`s powerPC cpu. These new high-end Macs have a Quad core archetechture with two seperate duel-core CPU`s and support for up to 16 megs of RAM and PCI-EXpress video cards. With the default video card being a 6600 128mb with support up to a NVIDIA Quadro FX 4500 with 512MB of video memory it appears these new powermacs are specifically aimed at profesional video and picture editing and also come with a heafty price tag as well.

[i]”Power Macs go dual-core

Apple has unveiled a major upgrade to its Power Mac range. In what is likely to be the last major upgrade to the desktop machines before Apple switches to Intel chips next year, Apple has used dual core processors for the first time.

Dual core processors have more efficient cache and memory management that enables them to work more efficiently and therefore faster. This contrasts with two separate single core processors sitting side-by-side, which the previous generation of Power Macs employed. They will also use slightly less power.

At the top of the range, the Power Mac Quad 2.5GHz is powered by two dual-core Power PC G5 chips with 1MB of L2 cache per core. Add to that a 1.25GHz frontside bus and Nvidia GeForce 6600 graphics with 256MB GDDR SDRAM and you have by some distance the most powerful Mac ever.

All three basic models in the range come with 512MB of 533MHz DDR2 SDRAM, a 16x DVD and CD burner (SuperDrive) with double layer support, three PCI-Express slots and dual Gigabit Ethernet ports. The two other models are the Dual 2.3GHz, which has a single dual-core processor with 1MB of L2 cache per core, a 1.15GHz frontside bus and GeForce 6600 graphics with 256MB GDDR SDRAM, and the Dual 2GHz with a 1GHz bus and GeForce 6600 LE graphics with 128MB GDDR SDRAM.

Unlike previous Power Mac revisions, all models support Apple’s 30in Cinema Display and if the GeForce 6600 is not powerful enough then the GeForce 7800 GT with 256MB of video memory and the NVIDIA Quadro FX 4500 with 512MB of video memory are available as build-to-order options.

The Power Macs cost £1,399 for Dual 2GHz, £1m749 for Dual 2.3GHz and £2,299 for Quad 2.5GHz. The Quad will not be ready to ship for three to four weeks. For more information go to

A fourth model is also available for users who require PCI-X slots but it does not have dual-core processors.
