Intel's Core i5 Analyzed and Tested (150+ Benchmarks)
The Benchmarks
To run our test, we tried to balance each particular CPU’s platform as closely as possible but given the differences in each chip’s requirements that’s almost impossible. We used the same make and model Western Digital Raptor 150GB drive for all four builds, the same 64-bit Windows Vista Home Premium SP2 build, the same make/model/clocked EVGA GeForce GTX280 and the same drivers. Windows 7 was available at the time of our reviews but we felt it would be best to use Vista as drivers were readily available for it.
The only real differences, of course, were the motherboards and RAM configurations. Although the Core i7-920 does unofficially support higher clocked RAM, we stuck with the official DDR3/1066, but 6GB of it. For the dual-channel Phenom II X4 and Core i5/i7, we used 4GB of DDR3/1333. For the dual-channel Core 2 Quad, we used the far more common DDR2/1066 as the vast majority of Core 2 Quad folks are running DDR2. For motherboards, we used three Gigabyte boards: the new GA-P55-UD6 for the LGA1156 procs, a GA-EX58-UDR3 for the LGA1136, and a GA-MA790GPT-UD3H for the Phenom II. For the Core 2, we relied on an Asus Maximus II Formula.
