Eight-core Mac Pro benchmark results
Benchmarks of Apple's new Mac Pro systems -- which began shipping earlier this year -- show how the latest systems stack up against each other as well as the company's older workstations. Overall performance ratings placed the Mac Pro 3.2GHz at the top of the charts in both 64-bit and 32-bit tests. Tests show that the performance difference between Apple's 2.8GHz and 3.2GHz Mac Pros is not as great as the difference between running 32-bit code and 64-bit code, according to the Primate Labs Blog.
Using Geekbench 2 software, benchmarks score against a baseline where 1,000 represents the performance of a Power Mac G5 running at 1.6GHz. The 3.2GHz Mac Pro scored 9,602 when running 64-bit code, while 32-bit processing revealed a score of 8,083 overall. Comparatively the 3.0GHz Mac Pro earned a score of 9,110 when processing 64-bit code and 7,742 while handling 32-bit instructions. The company's 2.8GHz Mac Pro scored 8,978 and 7,595 for 64-bit and 32-bit processing, respectively.
Integer and Floating Point performance revealed expected results, while memory and performance showed only slight increases for the top-end Mac Pro.
Primate Labs Blog tests revealed that the 2.8GHz Mac Pro running 64-bit code is actually faster than the 3.2GHz Mac Pro running 32-bit code, further stressing the performance advantages of running native 64-bit applications.

The overall increase performance between the 3.2 and the 2.8 is commensurate with what you might expect by the difference in processor speeds: about 106.67%.. but the difference between the 3.0 and 2.8 is only about 101.94%, which makes me wonder what the other differences are between the 3.2 and the 3.0 systems.
