Intel Leaks i7-2700K

Intel's Sandy Bridge CPUs were launched in January and so far, the desktop i7 lineup has consisted of three SKUs: i7-2600, i7-2600K and i7-2600S. Earlier this week, Intel released 16 new Sandy Bridge CPUs, but the desktop i7 series remained unchanged. Yesterday, Intel updated their Material Declaration Data Sheets (MDDS) with product code for i7-2700K. The exact product code is:
BX80623I72700K SR0DG
For comparison, the product code for i5-2500 is:
BX80623I52500 SR00T
Lets break down the product codes. The first two letters, "BX", stand for boxed unit. These letters would be different if the unit wasn't a boxed unit, for example "FF" is for non-boxed PGA988 units. There could be a third letter "C" which means it's a boxed unit for China market (hence there are two product codes for i7-2700K). After that, there is a five number code "80623". This is a specific code for all boxed desktop Sandy Bridge CPUs. Finally we get to the processor number which is the most interesting part and in this case, revealed the i7-2700K. There is still a separate spec code after the processor number and it's processor specific as well.
The specs of i7-2700K are unknown though. It's also a question whether there will be i7-2700 and i7-2700S or not. However, we would expect i7-2700K to carry similar specs as i7-2600K (four cores, Hyper-Threading, unlocked multiplier, 8MB L3...), but a slightly higher default frequency. Given Intel's history, 100MHz (one multiplier) increase sounds likely, making i7-2700K's stock frequency 3.5GHz with up to 3.9GHz Turbo. Price wise i7-2700K should also replace i7-2600K, making its price ~$317.
There is no word on the availability of i7-2700K. Leaked roadmaps suggest something equal or better than i7-2600K between Q3'11 and Q1'12. Considering that Intel just released new CPUs a few days ago, it seems unlikely that the release is imminent. On the other hand, it makes no sense to release i7-2700K just before Ivy Bridge, thus our guess would be Q4'11, around the same time as AMD's Bulldozer hits the shelves.

Depends on the usage. For gaming, 2500K is the king since games are poorly multithreaded and the bottleneck is elsewhere. For usage which takes advantage of multithreading, Hyper-Threading can boost the performance by up to 30%.Exodite - Saturday, September 10, 2011 - link
Indeed, I went with the 2600K over the 2500K for the sole reason of reducing compilation times.Turns out that was a great choice, as I were working on a minor web application for most of the spring term and I measured a compilation time drop from 40s to 28s in the early stages of development.
While 30% doesn't sound like a lot when you're measuring it in seconds, or single-digit minutes, it does add up when you're waiting on it for large parts of the day.

Meh. This is just to combat Bulldozer, pretty useless for current 2500K and 2600K owners.ilkhan - Saturday, September 10, 2011 - link
I'm more interested in the question of "will Intel release an i5-2600 and/or i5-2600k/s when these come out to replace the i5-2500(k).Doesn't matter to me, I bought my 2500K on release day, and not upgrading for a while. But its an interesting question.

I very much doubt the 3820 will be worth the money. Quad-channel memory and more cache aren't likely to do nearly as much for performance as the unlocked status of the 2500K/2600K.And it's going to be notably more expensive as well, when considering both the processor, motherboard and memory modules.

Not that I know, though you will need 4 modules to actually make use of the wider memory bus where S1155 chips can get away with two.Which naturally is going to cost more, even at the same total memory amount, unless you want at least 16GB memory in total.

Recently found out that the 2600K doesn't have Intel's Virtualization Technology for Directed I/O (VT-d), yet the vanilla 2600 has it. I sure hope Intel sees the light and makes sure VT-d is included in the 2700K, because it is utterly inane the 2600K lacks it.Same situation with the 2500 vs 2500K, as well. It is disingenuous of Intel to not include the same functionality in the K series parts.

Yes, I saw that article too. Pretty surprising, really. I thought the K series was all powerful.http://arstechnica.com/gadgets/news/2011/08/what-p...
I'd actually go with a vanilla i7-2700 if they make one, VT-d and TXT are things I'd actually want.

It very probably will be missing VT-d. It's pretty logical.VT-d is used by enterprise users and others who have financial resources. Intel does not want those users to overclock, Intel wants them to buy more CPUs.

trigate is the crown!!
