Intel Core i7-4770K Price, Specifications and Review:

This is the top-end version of Intel's new Haswell processor lineup, released on Jun 2 2013. The "K" suffix means it can be overclocked.Last year's equivalent version of this processor is the Ivy Bridge 3770k.The reviews show an average of about 7% better performance compared to the 3770k, although it varies from 1-20% depending on the application (this assumes neither chip has been overclocked).

There's also a decrease in idle power consumption (46W for 3770k down to 34W with 4770k, but didn't correct for motherboard differences so it's hard to tell exactly how much the processor helped). In contrast, under heavy load the 4770k's power consumption appears to be higher than the 3770k.

The 4770k has much better integrated graphics performance than the 3770k, although I would expect many people who buy this part won't be using the integrated graphics. If you have an expensive video card already, who cares? Still, some may find it useful.

One caveat with this "K" part (compared to the 4770 without K suffix) is that it does not appear to include support for the new TSX extensions. It's not clear why Intel left that out, and frankly kind of disappointing. Very little software makes use of these extensions right now, but it could be important for multi-threadded software in the future.

For new PCs the 4770k seems like a decent choice, although there's a pretty hefty price premium over the 3770k at the moment. I certainly wouldn't be eager to upgrade if I already had a 2700k or a 3770k.

For overclockers the value proposition is even less clear because the 4770k appears to run a bit hotter than the 3770k at the same clock speed, limiting maximum overclock potential.
