Remember the most important results are on the next page of the review which covers real world applications and game performance.
Benchmarks have their place, but actual applications performance is what really matters.
Details of the systems shown in the graph of results. Some explanation of the MacBench scores and test system components. Tests run at 1024x768, thousands colors. In actual applications, this tiny difference in memory bandwidth would not have any measurable effect, even if CPU speeds were identical. CPU speed is the primary performance factor as you'll see on the next page of applications performance.
