3770 vs. 3770S - difference in performance?

[Turbonium]

Is there a real-world (in gaming) difference in performance between the 3770 and 3770S? The latter is clocked 300 MHz slower at baseline, but both Turbo to 3.9 GHz. I suppose what I'm asking is: will both chips run in Turbo as much as possible during heavy workloads? Or is that not how Turbo works?

Real world in gaming......

Irony!!

But seriously, I have nothing to contribute here.

The non S will perform better under heavy load. Since the TDP limit and limit to Turbo is lower.

You essentially only buy the S model if you can only cope with 65W TDP.

The better question is which is cheaper as you can get a non s part and underclock it which in turn can drop the tdp as well as load temps.

Makes sense. Thanks.

I'm actually trying to decide between the 3570 and 3770... and leaning towards the 3570. The only tangible difference I see between the two is 2MB more cache on the i7 - not sure if that's really worth the extra 90 dollars. Hyperthreading (8 core emulation?) doesn't seem to be a big deal either, especially for gaming, where most things don't take advantage of anything beyond dual cores anyway.

It's probably worth the extra $90. Or at least provides $90 worth of additional performance.

The real question is, are you on a budget where that $90 would be better spent somewhere else? (A 3570 + SSD > 3770 + HDD, for instance. Or if that $90 meant getting a 7950 instead of a 7870.)

i7 3770 has a lower price/performance ratio than the i5 3570, but is still has a bit more performance to justify the expense. HT + Cache make a bit of difference on quite a few apps.

I read somewhere on these forums that hyperthreading can sometimes lead to worse results in games, which makes me a bit apprehensive to select the i7 (I'm not one to be bothered to always turn it off in BIOS before wanting to run a game... that would be inefficient and silly).

HT used to be detrimental for gamers but that was a while back and things have improved with OS scheduling and probably on the hw side as well. Nehalems do ok with HT on in games and I never bothered to fiddle with the bios for HT (leaving it on by default) since the Sandy's.
