27-inch iMac Benchmarks: Core i7 vs. Core i5

Illustration for article titled 27-inch iMac Benchmarks: Core i7 vs. Core i5

Updated: Core i5 iMacs are fast, but early Core i7 benchmarks show 30 percent performance gains. A good upgrade for $200 (which adds 10 percent to the $2000 price). Timon-Royer's graph uses Geekbench 2 results (OS 10.6.2). [Timon-Royer]

It is easier to take advantage of multiple CPUs in a synthetic benchmark than it is in the real world. You'll see a performance increase, but unless your application is designed to take advantage of all four cores, you won't see a gain this big. I'm too lazy to go look and see what methodology the benchmark utility uses. #imaccorei7benchmarks
