Although Futuremark tells us that PCMark 7 is able to utilize at least 16 cores (and, given the outcome of the Computation sub-test, we believe the company), the main battery of tests really only seems to exploit four. As a result, the Core i7-3820, with 2.5 MB of shared L3 cache per core and a 3.8 GHz maximum Turbo Boost frequency, actually lands in first place at its default settings.
We’re not particularly impressed, though; the Core i7-2600K really isn’t very far behind—and on a much more affordable platform. AMD’s chips and the Core i7-920 are the only losers here.
Overclocked, the Core i7-3930K flexes its muscle more visibly. The 4.625 GHz Core i7-3820 trails a ways, but still easily bests all of the processors operating at their factory settings.

If by "noticeable" you mean "perceivable to mere mortals", then no.
If you can in fact notice the difference between 105 vs 110 FPS, then you are a god, and you deserve only the best.
Intel did an awesome job with the SBE line - despite the fact that we're missing some wanted/promised features (native support for USB and PCI-Express 3.0. I'm waiting out for the PCI 3.0 cards before I upgrade my graphics... curious if the Asus P9X79 Pro will hold it's promises.
Thanks Chris for reviewing this processor. I felt like I went out on a limb getting this processor over the Extreme, but the $600 was well worth it.
FX-8150 benchmark with no AA says "68.8" FPS. I think it's more like "48.8".

Glad you're enjoying. You do, actually get PCIe 3.0 support, but no USB 3.0, unfortunately.
Dacatak,
Yup, typo--fixing now!
it is a good thing
Indeed, fixed! At 3.6 V, we'd have dead Sandy.
Intel has made sure reviewers dont highlight on this factor, and instead asks reviewers to focus on the 6 core performance.
Intel didnt release the 4 core 3820(at launch) for this reason, it makes it easy to compare to normal sandy bridge and would show that even with a socket that is double the size, and quad channel memory X79 doesnt give you any better performance than Z68.
I always buy the high-end but X79 is a big letdown, Intel knows it and they're trying to control the reviews so it doesnt look as bad as it is
This shouldn't be necessary. Same architecture = same per-clock performance. If you need numbers, look at iTunes, WinZip, and Lame benchmark results. If you need yet additional proof, check out the original Sandy Bridge-E review, where I explicitly run the results you're saying don't get run.
Finally, as is mentioned in *this* story, the CPUs didn't come from Intel. -3930K came from Newegg and -3820, which isn't out yet, came from an unnamed other source.
Thanks,
Chris
it cant be the yield in Intel fab are so bad that all 2011 CPU produce by Intel have only 6 working cores at best.
This is the same as LGA 1366 v. LGA 1155 once the later was released. 1366 offered higher memory bandwidth and more Pci-e lanes, but even most enthusiasts wouldn't get the higher end platform due to price for performance.
Most settled for the i5-750(or lower since you could overclock anything then) just like most are settling for the 2500k now.
