Processor Testing Methodology
Since Ivy Bridge is the successor to Sandy Bridge, it makes sense to directly compare the two CPU families. For this review, I compared the Core i7-3770K against the Sandy Bridge based Core i7-2600K. While the 2600K is one tick below the top-end 2700K, the only difference is a fractional increase in clock speed: a base clock of 3.5GHz and a turbo of 3.9GHz as compared to the 2600K's 3.4/3.8GHz clocks. That less than a 3% boost so the benchmark results you see here should be pretty much the same as you'd see with a 2700K.
I tested the Core i7-3770K processor at both its stock clock speed and the maximum stable overclock I could attain on all cores simultaneously, which was 4.7GHz. I'll have more on this in the Overclocking section.
Each CPU was tested on an ASUS P8Z77-V Deluxe motherboard with the same hard disk, memory, CPU cooler, and graphics card, so that the CPU was the only variable.
For a graphics card, I used a reference design AMD Radeon HD5770 running at stock clock speeds. Since the Sandy Bridge and Ivy Bridge integrated GPUs share L3 cache and memory bandwidth with the processor cores, the iGPU was disabled for all benchmarks except those specifically concerned with the iGPU.
Intel Z77 Express Test Platform
Let's start the benchmarking with an AIDA64 run in the next section.
