Benchmarks for all three 8-Core Penryn Mac Pros reported
Each of the three machines were configured identically with 2.00GB of 800 MHz DDR2 FB-DIMMs, Mac OS X 10.5.1 build 9B2117, and pit against a baseline, where a score of 1000 represents the performance of a Power Mac G5 running at 1.6GHz.
Additionally, each model was tested under Geekbench 2 running both 32-bit and 64-bit code for a more in-depth comparison of the systems' capabilities.
"Whatâs interesting about the charts [below] is that the performance difference between the 2.8GHz and 3.2GHz Mac Pro isnât as great as the difference between running 32-bit code and 64-bit code," the firm concluded following the tests. "In fact, the 2.8GHz Mac Pro running 64-bit code is faster than the 3.2GHz Mac Pro running 32-bit code."
