A couple of weeks ago I blogged about the performance of the new Mac Pros. Unfortunately I only had Geekbench 2 results for the eight-core 2.8GHz Mac Pro. I thought I'd follow up on that post with Geekbench 2 results for all three eight-core Mac Pros.
Setup
- Mac Pro (Early 2008)
- Two quad-core Intel Xeons @ 2.8GHz, 3.0GHz, or 3.2GHz
- 2.00 GB 800 MHz DDR2 FB-DIMM
- Mac OS X 10.5.1 (Build 9B2117)
If you're not familiar with Geekbench 2, benchmarks are scored against a baseline, where a score of 1000 represents the performance of a Power Mac G5 @ 1.6GHz. Higher is better.

Conclusions
What's interesting about the above charts is that the performance difference between the 2.8GHz and 3.2GHz Mac Pro isn't as great as the difference between running 32-bit code and 64-bit code. In fact, the 2.8GHz Mac Pro running 64-bit code is faster than the 3.2GHz Mac Pro running 32-bit code!
Really, though, if you're using a new Mac Pro you're got a ridiculous amount of processing performance at your disposal (even if you're "stuck" with a 2.8GHz model running 32-bit code).
