Amazing review, very complete and detailed!!

Greetings from Colombia!!

Since the Z68-based motherboards, which allow for enabling the integrated GPU as well as overclocking, won't be available until May, it would be interesting to see Sandy Bridge video transcoding performance on an H67 motherboard. It might just beat 990X in that category too.

love the 2600!

The TrueCrypt AES benchmark is questionable. The i5-2500K has the new Intel instructions (AES-NI) for encryption. But it's only 5% faster than the i7-i875K that lacks AES-NI. Maybe the i7-875K keeps up because of hyperthreading. My impression from Intel papers on AES-NI is that AES-NI (especially the enhanced version in Sandy Bridge) should accelerate encryption more than hyperthreading does. So perhaps the TrueCrypt AES benchmark inflates the effect of additional cores and threads. If the benchmark launches multiple instances of a file for encryption that result would occur. My impression, from a set of desktops with BitLocker, is that AES-NI has a greater effect than additional cores/threads on application launches, for example. Try the AIDA64 encryption benchmark (no, I don't work for them!).

It's sad Intel probably won't release Sandy Bridge features for socket 1366. Or if they do they'll just price it stupidly expensive or cripple it in their usual fashion. Socket 1366's biggest remaining asset of six-cores is still basically unobtainable unless you have $600 to throw away. You still pay $380 just to get a 32nm xeon with HT on 1366 with a usable overclocking multiplier, but that's with 2 cores disabled.

Intel just wants 1366 to go away it seems.

So the 2600K is the best for gaming. Thought so....

Waiting for 2800K and 2900K....

Since when is 1.288V under load the 'nominal core voltage' on the 2600K? I'm guessing you dialed in load line calibration to the highest settings?

This clearly shows that -for 1st time- LGA-1366 is just 2nd best for Audio. Add the ICH10 high power consumption and its mostly gone...
When you work in a studio you need fanless noiseless gear and that typically goes with low power consumption (lower count of fans -if any-), which is fairly the same you require when going on tour (and choose a low power matx portable system) And that is significantly achieved with Sandybridge, and obviously Ivybridge.

By the way... Sandybridge tech signals the first time an important segment of sound engineers, musicians, etc are considering the use of notebooks on professional sound activities... excepting the fact that desktops is yet the almost-only way to plug our expensive, dedicated pro soundcards.

Thus, if the remaining question of the processing advantages of 2600k with fully speced two channels v/s LGA-1366 with three channels of RAM is cleared, then I'll have to decide on a 2600K based system or alternatively wait almost a year for the LGA2011... plus Intel expected Ivy prices.

For first time I am considering LGA1155 !!!

Considering the i5-2500K is 100€ cheaper and second to i7-2600K, its the clear winner here.

The i5-2500K is indeed impressive. Nearly the same performance as the i7-2600K in games, and not too far behind in most other tasks.

Great article, but 1000 bucks for a cpu? I doubt its worth 1000 bucks if you can get even close to it with any other cpu that's half as much or less that's just outrageous.

If you purchase a 300 dollar cpu and get 10 frames per second less in a game I'm wagering that 95% of the users wouldn't notice that loss of 10 FPS.

That 600 bucks you saved is better off spent on an SSD and video card.

one of the best reviews so far at Xbitlabs

The best article I have read regarding high end LGA1366 vs Sandy Bridge.

Saved me A LOT of aggravation for a long time to come as I was jsut about ready to purchase a new workstation (dual LGA-1366's).

Now I'll make do for a bit and wait for their replacement's the Xeon Xeon E5-2600/Sandy Bridge-EP/Socket R.

Thanks Xbit. Well done.

Great article.

This is what keeps me coming back to Xbit.

How would a higher gfx load skew the outcome?
