Intel Core i7 3770K review

The fastest real-world CPU on the market right now

With AMD a no show for this contest, it's all about the comparison with the incumbent Intel chips. Representing the old generation is our trusty Core i7 2600K. It's 100MHz slower than the 2700K, but otherwise representative of the state of the art in Sandy Bridge terms.

They're aren't any fireworks in the standard suite of benchmarks at stock frequencies, which is what we were expecting.

That said we had hope those new 22nm transistors would make for a bit of an overclocking beast.

As it is, the 3770K still overclocks really well. It's just no better than the 32nm generation.
