What's the frequency, Kenneth?

And, just like the Sandy Bridge K chips, the 3770K is a doddle to overclock. Just by adjusting the Ratio Limits to 47 and using the stock 100MHz base clock, I got my sample to reach 4.7GHz and run stably at that speed on air cooling.

To compare the old and new, I lined up the i7-3770K against the Sandy Bridge Core i7-2600K, which I happened to have to hand and which is only 100MHz slower than the i7-2700K, the new chip's closest match in the Sandy Bridge series.

Apart from the move to a 22nm process, the other important IVY Bridge improvement is the new integrated GPU. There are two versions: the HD 4000, which is for high-end CPUs like the 3770K, and the less powerful 2500, which is aimed at the middle of the market. Its most important feature is - drum roll please - Direct X 11 support, a feature that was noticeable by its absence in the Sandy Bridge graphics core, the HD 3000.

With the die shrink comes better power consumption, the TDP (Thermal Design Power) of the i7-3770K falling to 77W, some 18W less than the i7-2700K. This is quite something when you realise that both four-core parts share the same 3.5GHz clock speed.
