Performance delta between a 2600k and 3770k shrinks on OC.
Higher speed memory produces some gains that are more tangible over 2600k (3DMark 11 Physics test)


Other than that a 5-15% gains, lower amount for games, higher for synthetic tests. Graphs are a pain in the a$$ to view, the text is too small to read. The memory speed comparison table near the end and OC tests are interesting to read.
Never heard of http://wccftech.com until today... kind of wish I hadn't. Extremely misleading graphs.

Not worth upgrading, but is the logical pick if you're buying a processor today.

Kinda disappointed in the OC results from reviews. Seems like Sandy Bridge does better for OC and Ivy often have issues reaching the same level as Sandy at a decent temp/voltage.

It is impressive that 3770K used the lowest power at idle and load put Bulldozer and my CPU to shame. 2600K max OC at 4.8GHz could not get passed 4.9GHz 3770K max OC.

glad I didn't wait for ivy bridge. Seems like it's barely an improvement over SB.

Gotta' be honest, except for a handful of situations I'd argue it's barely an improvement over the Bloomfield I'm presently running, at least in real world situations.

I think we're at a point now where our hardware is so stinkin' powerful in relations to the software we're running- we've a long ways to go for the software to catch up. I do like how a lot of the video and photo editing software can utilize the GPU to speed up rendering and such. It is a step in the right direction.

For me coming from an e8400 it a no brainer especially since same price point, but yeah I don't see why people on SB would upgrade since it only a tick+

This is interesting though:

Quote:
Clock for clock, Ivy Bridge (which is a "Tick" on Intel's roadmap) does offer performance improvements over Sandy Bridge, albeit mostly in single digit percentages. This is good news as the new processors will directly replace the old ones at roughly the same price points.

From the large pool of CPUs that we have tested/binned, Ivy Bridge uses 25% less power on average clock for clock due to the lower voltages required (in this case Sandy's 1.48v to Ivy's 1.27v).
Ivy Bridge's on-die temperatures (TJ Max of 105 degrees celsius) are a lot higher than Sandy Bridge, indicating possible high electrical leakage on the new process or a different measurement method. Note: Temperatures != Power, although there is some correlation.

Ivy Bridge is a (subzero) overclocker's wet dream, able to hit core frequencies near 7GHz with no cold bugs (unless motherboard induced).

In general, Z77 boards are better made and engineered (shorter electrical traces, better component placement) than their P67/Z68 predecessors, doing away with niggling BIOS firmware bugs and dodgy VRM implementations.

I don't know where you got that a 3770K just hit 65c at 4.6g because every review shows it hitting near 90c when hitting that kind of overclock.It might idle at 65c but if you run a load like prime95,it will be doing over 90c in about 15 minutes.Even at guru they showed it hitting 89c.But if you do not plan on overclocking and want a pretty fast internal graphics and have a older Q6600 chip then this looks like a decent upgrade.But if you already have a i5-2500K or a i7-2600K then there is no point in upgradeing.To be honest if you are running a overclock i7-920 at 4gigs then I would still not really recomend a upgrading if you are just a gamer,because there will be less the 5% to 10% improvement in games but in other areas you will see a nice inproment as far as power consumption.

I wonder how HT affects IB temps? My 920 drops like 10-15C when I disable HT, if I recall correctly.

Sandy Bridge and Ivy Bridge CPUs don't use HT I believe.

That makes sense from what I understand HT makes the cpu work a lot harder according to research I have done which in turn raises temps more.

One reason I am not going with any i7 chip, for gaming HT makes no difference so figured I rather it be cooler and why spend the extra money.

It seemed HT makes big difference in games like Dirt 2 etc that take full advantage of multithreading.

i5-661 HT on 95.47fps
i5-661 HT off 72.02fps

I guess there might be exceptions but from what I understand 95% of games will not make a difference. If I can get an i7 for same price I would, but for an extra $100 I put it to my SSD
