Haswell scares me

So a while back I wanted to buy an i5 3470 + MSI Z77A-G41 for a new build. This combo seemed pretty good from the money standpoint (my budget is a bit tight) and also because I wasn't planning on OCing.

Recently, someone pointed out that I should instead get an i5 4570 because it's supposed to have 5-7% better performance, while the price is basically the same.

That sounded great, BUT, I can't find any benchmarks for this CPU or indeed any real feedback at all. Except that it's more power-hungry and generates more heat. Which is a problem, I'm generally very weary of heat. Don't get me wrong, I would buy an aftermarket cooler in any case (Intel's heatsinks are a freaking joke), but I would much prefer to have a CPU that generates less heat to begin with.

So my question is to those who own or have had the opportunity to test this CPU. How does it really compare to i5 3470 performance-wise and heat-wise? Which one would you recommend? And apart from buying a no longer supported microarchitecture, is there any other reason why I shouldn't go for ivy bridge that has nearly the same (unless I'm wrong in this presumption) real-world performance?

The only real thing going for Haswell over Ivy Bridge (and even Sandy) is the beefed up iGPU. If you have programs that use OCL and can make good use of the iGPU, then you should go with Haswell even if it runs a little hotter. CPU wise, not worth the difference in performance over heat.

Examples of programs would be mostly Video Codecs. LAV has QS and they'll hopefully add OCL support sooner than later; it has CUDA support at least.

So, going to the main question, unless you plan to give good use to the iGPU, don't bother if you're concerned about heat. And before people start trolling, Haswell DOES have higher TDP.

Cheers!

Passmark shows the Haswell to be about 10% faster.

The chip draws a little more, since the moved the VRM on to the CPU. But the overall system draw at the wall will be the same, or perhaps a tiny bit less. So there is no difference in the amount of heat produced.

first i wud like to tell u
1.A Z SERIES BOARD IS AN OVERKILL FOR A LOCKED PROCESSOR
2.just get a better cpu like 4670 and a h87 or b85 board
3.haswell do produce more heat but it is not a concern withlocked version its more relavent to k versions
4,haswell is 10% faster than ivy

verdict get a 4670 and a h87 board

See, I don't trust Passmark and similar tests (although I'll admit I don't know much about how they're conducted), but I'd want to see actual performance. Like FPS in games or render times in seconds etc.

Thanks for the info. Actually I'm not planning on using the iGPU at all.

So far I'm leaning towards the cheaper i5-3470. Unless someone has any other arguments to persuade me? :)

just keep in mind that all non-k i5 2nd,3rd,4th generation processors give the same performance (except S and T version) so you won't compromise on any performance

4670 marginally beats the glorified 3570K according to this review: http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/61451-intel-haswell-i7-4770k-i5-4670k-review-16.html

40 FPS difference at 400 FPS range isn't that impressive imo.

And IIRC since the 3470's performance is very close to the 3570K's, I'll stick with the cheap and effective 3470. Thanks!

P.S. If my budget weren't so tight, I'd probably go for the 4670 with some quality cooling, but unfortunately it's not, so 3470 + CM Hyper 212 it is. :)
