    Since the TDP hasn't changed, it's pretty clear that Intel is recovering 6-core i7-39xx units that have 1 or 2 defective cores and selling as 4-core. AMD has done this with their many Core units as well. Reply

    Actually all the six core socket 2011 chips are binned 8 core chips. I suspect yields are good enough that Intel wouldn't need to cripple additional cores on their larger chips. Various reports are indicating that this is a new die 294 mm^2 in size. Reply

    That's true, this is a new die. Anand covered this in our review (see the table)

    are their any immediate plans for the chipset to include PCIe 3 as well. Reply

    Regarding the CPU image and others like it, sharpie does offer thinner permanent markers which would be easier to write with:

    Just sayin' ;)

    Haha, you need to bug Anand about this, it's his picture and sample ;-) Reply

    Yes, but do you know Anand's handwriting well enough to out him as the perpetrator of this bad penmanship :D Reply

    If you imagine to look at it from bird's eye view. It's like someone doing the Chinese ribbon dance. :D Reply

    If I'm not mistaken, Intel is the one that writes on the chips -- but then again, it might be Anand. Reply

    Seen that type of hand writing before on this site, so I doubt it's Intel, but if it was. I wonder how much that person gets paid just to write model numbers on ES CPUs to be sent out for reviews. Reply
  • Kristian Vättö - Wednesday, February 15, 2012 - link

    Here's a picture from another review, the handwriting isn't any better :D So Jarred could be right, it's Intel who does the writing

    Nope, Intel sends these things out bare-faced in trays, sans sharpie.
    Lots of people just have bad handwriting (I'm looking at you specifically fellow engineers) ;)

    Another reason, Ivy Bridge - E next year.

    Grab the platform now, maybe a 8-core IB next year.

    That's true, but since we don't have any details of IVB-E, I think it would be premature to list it as a reason. We don't know when it will be out. We don't know how fast it will be. There is no guarantee that IVB-E will bring more than four cores into the ~$300 market, which would again make it similar to LGA 1155 offerings. Reply

    2600K is still better than 3820, since you can overclock. A bit of a waste to pay hefty price for LGA2011 mobo and not get 3930K. And if you *really* need the memory advantage, then Sandy Bridge Xeon is a better way to go. This 3820 chip is made for a very very small niche of folks. :) Reply
  • Death666Angel - Tuesday, February 14, 2012 - link

    You can overclock the 2600k with the open multiplier, but if you read the articles on Anandtech about SNB-E, you will find out that the 3820 is partially unlocked and can also overclock via BCKL. "By default Sandy Bridge uses a 100MHz bclk, but SNB-E allows for 125MHz, 166MHz and 250MHz options as well." I doubt there will be great differences between the two, overclock wise. Reply

    How come i7-3820 is cheaper and 200MHz faster than i7-2600k??? Reply
  • Rick83 - Tuesday, February 14, 2012 - link

    Because Intel gets a bigger cut on X79, I suspect. Reply
  • Taft12 - Thursday, February 16, 2012 - link

    Judging from the retail pricing of LGA2011 boards, I think we have a winner! Reply
  • Kristian Vättö - Wednesday, February 15, 2012 - link

    You pay a little extra for the unlocked multiplier in i7-2600K. The regular i7-2600 is the same price as i7-3820. Reply

    And what happened to $1050 for the 3960X? Reply

    I still can't find somewhere to buy the i7 3820. Intel says it's released, but Newegg and Tigerdirect don't list it. Amazon still indicates 1 to 2 months. Some other retailers are saying maybe next week at the absolute earliest. Stories in Europe and Asia indicate they already have the chip. Did these things get shipped to the US via boat instead of jet? Also, I have yet to find someone selling the CPU below $315. Most retailers are charging $330 and up.

    I'd like to buy an i7 3820. I'm replacing my current main machine which is still running a C2D P8400. The i7 3770 is still two months away and should have the same price tag and performance. I don't see the need to wait for the slightly lower power consumption. It's getting rather annoying to have to wait and wait and wait for Sandy Bridge-E. The shortages and delays are really bad.

    Yes Asia already has them

    I ordered mine yesterday (Monday 2/13) from http://www.seaboom.com/. They called me today and said it was shipping this afternoon. I've never ordered from them before, but it's a sealed boxed product, and is apparently shipping directly from Intel, so I figured what the heck. Reply

    Did you get your 3820 yet? I might wind up ordering from Seaboom too. I'm really frustrated with the way Intel has handled this latest release. Reply
  • selimnairb - Friday, February 17, 2012 - link

    Ordered on Monday, received it on Thursday, used free ground shipping. It shipped from Georgia, which is close to me. Built the machine last night, all is well. Reply

    I would buy one today if i couod find one for sale.
    I just burnt out my x58 i7 920 board.
    I use applications, cad, fea, revit, that benefit from memory. I could get a z68 setup much cheaper, but the lack of memory is a downfall.

    so between the 2 of them, which one would you choose? (imagine you overclock both of them) Reply

    I purchased a new ASRock x79 Extreme 4 socket 2011 MoB & a i7 3820 CPU today. I got this 0xAF error. The BIOS is 1.1-15B as written on chip. This error stops startup.

    The problem with the X79 Extreme4 is the error 0xAF and no startup. This occurs with all ASRock X79 Extreme4 with a i7 3820 CPU as I have now found out.

    You need to get a new BIOS chip, the L6.2 BIOS Chip or higher from ASRock to fix the issue and you need to change it on the MoB your self.

    The L6.2 BIOS Chip may be the only chip available from ASRock for now.
    They are still shipping X79 Extreme4 with BIOS 1.1, which does not support the i7-3820...

    Why are we not warned before purchase as it's obvious ASRock know?
