These tests use the MemoryTester 'compute' command. MemoryTester is part of diglloydTools.
This is a compute intensive test with some memory access. The MacBook Pro is not quite as fast as the 3.33GHz Mac Pro (20% slower with one thread), but it scales very similarly.
With 6 CPU threads, the 2.3GHz MacBook Pro takes 74% longer, which is slightly faster than what is expected based on the single thread performance (6/4 * (1.105/.921) = 1.8).
As expected, the 3.33Ghz Mac Pro widens its lead considerably beginning with 5 CPU threads. Which shows that many programs (as tested in this review) are simply not exploiting the 6-CPU cores effectively (which can be due to memory bandwidth even for very well written programs).
Time in seconds, lower is better
