Just a quicky - a very similar looking review of the 3570K will be going up tomorrow, and they'll probably share the same comment thread - the bit-tech word droids can only write these reviews so quickly after all. I'll just go change their grammato-coils and we should have the 3570K ready in no time. We'll also be covering Intel's HD 4000 graphics, the Z77 chipset, how to overclock both CPUs and some choice Z77 motherboards in separate follow-up articles over the next few weeks.

Great review! :)
1 x 16 lanes or 2 x 8 lanes, although that somewhat defeats the point of PCI-E 3.0 I'll admit.
Also, I'm hearing that availability sadly won't be instant - rumour is 29th April for e-tailers to release stock. Bummer.
Bit-Tech seem to have glossed over the rumoured cooling issues. Real-world power draw is all well and good, but I've heard it's the size of chip in contact with a heatsink that makes the difference. Can we have operating temperatures? Overclocked and non-overclocked?
Should I worry about the high temps? You guys are using an H100 and I'm currently planning on transplanting my Hyper 212+. If you're hitting 100c on that, I can only imagine what an air cooler will do. (melt)

At the risk of sounding like fanboy, I still don't see anything that makes me want to upgrade my 920. I'm happy to leave until next year, I think. :D
ditto, it does everything i want it to very well, so no upgrades for me until i need them. the pull of shiny new hardware is strong, but the reality of my bank balance stronger

Sure, that's hot, but then so are similarly clocked 2600/2500K's. You'll need a big cooler or WC to see 5GHz.
At defaults, it idles at 28°C in a 19°C ambient. Under load this rises to 60°C, again in an ambient of 19°C.
From our experience with the chip, it's no cause for concern. With the H100, the coolant doesn't even heat up too much - these high temps seem to be inside the CPU. On a more standard cooler such as the 212 someone else mentioned, I'd expect 4.4-4.6GHz at reasonable temps, no problem at all. You can use much lower voltages at these overclocks (1.2-1.3v).

Now now bindi,got to share! Also, the Asus site wasn't serving the images of the Gene correctly :P

But the issue with temperature isn't the risk of a chip breaking down: it's noise. Load delta of 60°C is very high (I'm assuming this is non-overclocked?). Thus fans have to run at a higher RPM = more noise. The cooling issue was the one thing that was worrying people and it's been largely glossed over. After all, the performance gains over a Sandybridge chip seem negligible - so cooling noise becomes an important consideration when thinking about purchasing. It's almost like you guys don't want to piss off Intel.
EDIT: Or to put it another way,
If I can run Core i7 2700K with cooler H100 at temp. X under fan RPM Y, what fan RPM would I need to run the 3770K at temp. X (same cooler)? Or, what temperature would I get if I ran the 3770K at RPM Y?
sorry but them temps are crap. ive just put a h40 on my 2700k running at 5.0ghz with 1.43v and its only hitting 82c when stressed. granted its 20c hotter than my full watercooling kit but its not that hot

I have 72ºc with my 2600k@5ghz... And I'm on air... well, my Silverstone FT02R helps :D

Tweaktown were able to draw much stronger conclusions about the temps because they had several Core i7-3770K chips to compare - Intel only sent us one. Not sure how their overclocking section is clearer either - all they've done in addition is provide a CPU-Z screenshot, other than that thet have nearly identical information.

Should we expect a 6 core 2011 equivalent?

9x0 @ 4 GHz here.... 62 degrees at 100% load Corsair H70 + 2 38mm fans.
Next !
dunx
P.S. 2 PCI-E 3.0 slots @ x8 = 2 PCI-E 2.0 slots @ x16 so plenty of bandwidth there, IMHO.
