Power Consumption
At idle, the 3960X's power consumption is barely discernible from the 2600K. Under load however, Sandy Bridge E can draw significantly more power. We measured 35% more power draw over a 2600K. The added power consumption makes sense. The chip has more cores and a larger cache, without introducing a more power efficient architecture or a new manufacturing process.

You assume correctly.As stated in the article, the 3820 is due out early next year and expected to run at about $300.
If you look at the 1st page of the article, you'll note that the 3820 is a little faster than the 2700K, with the same max in turbo mode and a larger L3 cache.

Except that the 2700k is unlocked and the 3820 has a severe overclocking limit.theangryintern - Monday, November 14, 2011 - link
Thanks for the great review, Anand. I had been waiting for SNB-E to do an upgrade from my X58 Core i7, but now I'm thinking of saving some money and going with a regular Sandy Bridge, the gaming gains just aren't enough to justify the added expense.Makaveli - Monday, November 14, 2011 - link
That makes no sense there are no gaming games going from X58 to SB!You will still be GPU bottlenecked on most games!
And a whole new build will be an added expense for no gain in Games!

Not much to see here except over-priced CPUs and mobos. Nice to see Intel fans smartening up and passing on these cash cows.Lazlo Panaflex - Monday, November 14, 2011 - link
Hi Anand, thanks for the review :)Apologize in advance if this was asked earlier, but what specifically is your criteria for determining a stable overclock? For example, do you run Prime95, large FFT's for a predetermined period of time, or perhaps IBT (Intel Burn Test) for a certain amount of runs? Or do you utilize some other tool? Just curious, since this question often pops up in the CPU forums, and everyone has their own opinion of what constitutes a stable overclock.
Regards,
LP

LOL. Supply and the mand is the cause. Jacking up the price is the effect. You are a bit mixed up it seems.Also, in the consumer market having the fastest CPU (or GPU) that you sell for a ridiculous price doesn't mean that someone buys it.
How many people buy a HD6990? Few, and that's why supplies are so scarce.
The 3960X is a "show off" chip that claims performance crown. Anyone in the right state of mind will not buy it: it is just not worth the money it costs, unless you're in absolute need of few extra % of performance.

We have chips priced at $1000 because the market has shown that it is willing to pay that amount to get the top-performing chip. It doesn't matter that AMD doesn't have an entry in that segment, because if it did, then we'd probably have AMD's FX-9300 or something priced at $900, while Intel sells their 3960X at $1100.This was the exact case when AMD was competitive, and their FX-57 was sold at $1100, vs Intel's Pentium EE which was going for $999. Was there a competitive AMD at the time? Yes. They were even in the lead. Were prices still jacked up? Yes.
The $1000 CPU will only go away if we, as consumers wise up and say we are not willing to pay that much money for a chip.

Lack of Quick Sync is not nearly the negative that the reviewer seems to think it is. It is not a well supported technology and not many people would use it on a day to day basis. This shouldn't even be mentioned in the article unless you also want to bring up support for Intel Viiv http://en.wikipedia.org/wiki/Intel_Viiv.
