CPU-Dependent 3D GamingStreet Fighter IV uses a new, built-from-scratch graphics engine that enables CAPCOM to tune the visuals and performance to fit the needs of the game, as well as run well on lower-end hardware. Although the engine is based on DX9 capabilities, it does add soft shadows, High Dynamic Range lighting, depth of field effects, and motion blur to enhance the game experience. The game is multi-threaded, with rendering, audio, and file I/O all running in different threads. The development team has also worked to maintain a relatively constant CPU load in all parts of the game so that on-screen performance does not change dramatically in different game scenarios.
I ran the Street Fighter IV benchmark at its lowest resolution (640x480) will all graphical features turned down to the minimum possible settings. This makes the video card much less of a factor in the results, biasing towards processor performance. We see the same pattern we've seen in other tests, with the new Ivy Bridge CPU turning in a stock-clocked score just under 10% better than the stock-clocked 2600K.

Ivy Bridge does enable the mainboard's PCI-E 3.0 features, but I don't think that your card is 3.0 compliant. If there is a huge advantage to PCI-E 3.0 as opposed to 2.0 operation, that would make me want to change over.
Thanks for the review. It was a good read.
In any case right now PCI-E 3.0 bandwidth improvements have no discernible effect on graphics performance since no card is anywhere close to saturating the bandwidth of 16x or even 8x PCI-E 2.0.
Speaks volumes for the entry-level market, though, not much for the market the 3770K is in.

I have an A8 APU and when paired with the 1GB XFX HD6670 Radeon card I have, it performs pretty good. It's a good overclocker and most of the available socket FM-1 mainboards have a ~lot~ of useable features on them. It represents excellent value for the low cost of ownership.
But, as you say, it is Apples and Oranges in the marketplace.
If you look at some of the other articles going around the net on this topic, you'd think IB is the second coming.
Hilbert Hagedoorn (Mr. GURU 3D, himself) says that the i7-3770K is an excellent overclocker, (guru3d.com/reviews) while you say otherwise.
Is there such a large difference between Engineering Samples, or is this the same-o, same-o from Intel, where there's a large gap in performance from one (supposedly) identical cpu to another?
It's fairly common knowledge that retail bought cpu's OC better than the engineering samples given out to review sites. Is this the case concerning the cpu that you tested, and that a retail version may actually OC much, much better than the one you have?
If so, then the reviewing of any free sample should never be done. Ever.
If any reviewer can't afford, or is too cheap, to buy a random retail component for reviewing, then the review is completely suspect, since it does NOT apply to what real people buy themselves off-the-shelf.
So yes, in answer to your question, there is a difference between engineering samples; in fact there's a difference between retail samples, as any overclocker knows. And as for "large difference", the 4.9GHz Hilbert reached was a mere 4.2% better than the 4.7GHz I reached, so your definition of "large" seems a little off to me.
No review sites normally buy retail samples of the products they review. Even if we did, waiting for a retail Ivy Bridge CPU would mean you'd read all these reviews weeks later than you would otherwise. And I'm not sure I could wait that long for your appreciation.

I'm not going to bother visiting his site to find out, but I presume he might have cooled it differently or simply received a better sample.
Going to hate forever?
It looks possible that even if it brings better power usage, throttling might bring overall performance down if a manufacturer isn't attentive to their cooling system design.
So doubling the potential throughput from x16 2.0 to x16 3.0 won't make any difference because no current software is trying to pump that much information across PCI-E.
The real win for PCI-E 3.0 would be with non-video card devices, like PCI-E SSDs. Of course the trouble is that with current Ivy Bridge systems only the CPU has PCI-E 3.0 lines (the X77 Express chipset is still limited to PCI-E 2.0...and two SATA6 ports...and four USB 3.0 ports...because Intel is lazy), so the only slots with this connectivity are the one or two X16 slots a board will have, and these aren't the slots you'd put a non-graphics card in. Sigh.
Where this will make a real difference, as I notice in the review, is with laptop/ultrabook/portable devices. The lower power draw should make a real difference in battery life, allowing either smaller batteries (and smaller devices), longer life with the same size batteries, or any combination. This would be hard to test since you'd need two mobile devices with the only difference being the processor...and I only had a desktop CPU anyway.
Just today I have gotten three spams claiming they were new posts in Benchmark Reviews articles (including this one).
I enjoy reading the reviews here but if you guys can't do anything about the spam, I'll have to unsubscribe.
We immediately remove comments and block IPs, but unless you want to enter a long complex code then one spam message per week isn't the end of the world.
Last week I started getting a few more and today there were three when I got home for work. There's no way to block the sneaky buggers without blocking Benchmark Reviews.
If it goes back to one a week that would make me happy. If it increases again then I don't think I would stick around. We'll see how it goes. Maybe you guys can change the character test to four or five alphanumeric characters instead of three, or two short words. If it's spam bots that might help, if someone posts the spam manually then it wouldn't.
Good luck with it anyway.
