I own both an i7 970 and a 2600k, and while the 2600k is better in price vs. performance terms (it's half the price), the Gulftown is actually quite a bit faster in many things.
There are actually a few areas where a stock Gulftown comes close to an OCed 2600k, and a 5GHz 2600k cannot touch a 4.2GHz Gulftown in several areas, with the performance difference being well over 15% in at least a few.
Of course SB is more power efficient than Gulftown, it's more power efficient than almost anything in the entire 5w+ category.

SB-E was tapped out and tested internally a long time ago.
These figures are from internal benchmarks, and they are likely accurate, just full of spin.
See that "up to"? That means in those few situations that leverage the new instruction sets that Gulftown doesn't have, it can be that much faster.
Intel never once claimed a 36% jump in overall performance, and no one who can comprehend what they've read could think they have.

Ivy Bridge is codename for Sandy Bridge E and will go under the X79 Platform as Socket 2011.
Ivy is not SB-E. Ivy is a 22nm revamp of the original SB for LGA-1155.
SB-E is SB with more cores, more cache, more memory controllers, more PCI-E lanes, and a QPI bus on LGA-2011. It's still 32nm and has next to no real architectural improvements over SB.

Also, they're comparing 3.46GHz against 3.33GHz. So multiply results by another 4%.
Of course SB E will clock higher as well by another 10-15%. When you factor that all together:
15% becomes 36%
36% becomes 60%
Yes, when both chips are OCed to their limits, SB-E will like pull a head more; though the 990x does clock pretty well (4.4-4.5GHz is not uncommon on air), and with 50% more cores and almost double the cache, SB-E may well not clock as far as SB does.
Also, as a nitpick, X79 doesn't have a memory controller, SB-E does.
