Apple Mac Pro Quad-core Xeon easily beats Power Mac G5 Quad

“The standard configuration of the Mac Pro outperforms its PowerPC-based G5 predecessors by a wide margin, helping to justify Apple’s 2005 decision to switch to processors from Intel. What’s more, the system powered by two dual-core 2.66GHz Xeon chips narrowly missed becoming the first machine to ever record a Speedmark score of over 300,” James Galbraith reports for Macworld.

Galbraith reports, “We’ve ordered Mac Pros in a few different configurations and will test them as they arrive. The first machine to come in was the standard configuration—the $2,499 Dual-Core Mac Pro with two 2.66GHz Xeon processors, 1GB of Fully-Buffered DDR2 RAM, a 250GB hard drive, a 16X SuperDrive with double-layer support, and an Nvidia GeForce 7300GT graphics card. This out-of-the-box Mac Pro configuration earned the highest Speedmark score ever recorded in our tests.”

Benchmark duel: Apple Mac Pro vs. Power Mac G5 – August 10, 2006


  1. When G5 was released, Intel came out with pentium D, later, the Core Duo and then, Core 2 Duo, so XEON is beating a processor from a 3rd generation ago. The only upgrade it has received was from single core to dual core, but XEON only beat G5 for a small difference, I am quite sure that if G5 get to 3Ghz, not even the XEON 3.2Ghz will beat then. The problem is that IBM does not push their processor speed to much.

    Other issue is that Apple only change to intel not because faster processor, but for Performance per watt and also to increase their market share making the Mac “PC compatible”. It is like a “Trojan Horse”, once the PC user tastes the superior OS in Mac, they will never go back to windows.

  2. Apple changed from the G5 because they couldn’t get it into a laptop and Apple’s laptop performance was lagging. Also, heat was an issue. Surely you’ve heard of the problems from the G4 wind tunnels and the G5 fans taking off? There were some problems with the higher-speed G4s and G5 and IBM was doing NOTHING about it. They said in public that Apple wasn’t important, so Apple made the change to Intel.
