The Socket

With an integrated memory controller, Intel needed a new pinout for Nehalem and the first version with three 64-bit DDR3 memory channels features a 1366-pin LGA interface:


LGA-1366 (left) vs. LGA-775 (right)

The socket is noticeably bigger than LGA-775 as is the mounting area for heatsinks. You can't reuse LGA-775 heatsinks and instead must use a heatsink with mounting holes more spread apart. As far as we can tell, the same push-pin mounting mechanism from LGA-775 is present in Nehalem which is disappointing.

With a larger socket and more pins, the CPU itself is obviously bigger. Here's a shot of our Nehalem compared to a Core 2 Duo E8500:

Intel will obviously have dual-channel versions of Nehalem in the future, unfortunately it looks like they will use a smaller socket for mainstream versions of the chip (LGA-1160?). We won't have to deal with socket segmentation just yet and it is always possible that Intel will choose to stand behind a single socket for the majority of the desktop market, reserving LGA-1366 for a Skulltrail-like high end but the strategy is unclear at this point.

    Crysis- etc. :

    Pete, you can be very happy knowing it will do folding like mad, and you can fantasize that you've cured cancer while you spend your money for some tax subsidized already to the hilt University program, because you're such a good and loving person.
    ( I know YOU didn't mean anything like that - see sarcasm! )
    In the mean time, the OLD HT single core chips will do just fine cranking most games, and dual core or core2duo or 2180 or some other then $40 chip will be a few percentage pts. shy.
    My gawd, they've got our number.
    I bet they "unlock it !!!!! " OMG ! for like 2 grand if you're cooooool you can get one!

    I know it may be exciting but the article sounds fan-boyish. For most of the marks it shows what intel is claiming 20-30% boost. He gets one mark to go 50% and now it's 20-50% boost?? He compares in another mark AMD 21 and nehalem 14 and says it's almost 50% faster!!! and then compares penryn 18 and nehalem 14 and says it's 28%. I think the AMD mark was more like 35%.

    As I've said before everybody knows AMD was going to hurt themselves in the short run by buying ATI. If they didn't buy ATI I think things would be very different. Now that the last year of payments is being made for buying ATI AMD will be able to get back into the game.

    Intel has only now integrated the memory controller. Everybody knew as soon as they did they would see a nice bump. They haven't had any significant innovations in a long time. AMD is in the same position they were before K8. Just give them some time to finish absorbing ATI, then watch out- fusion is just around the corner :)

    What kind of idiot fan-boy drivel is this?

    "He gets one mark to go 50% and now it's 20-50% boost??"

    Ummm, yes?

    1, 2, 3, 4, 8

    What is the range of those numbers? 1-8, right?

    Does the majority of them being being in the 1-5 range somehow negate the fact that the actual range is 1-8?

    THINK PEOPLE!

    You're the one that sounds like a fanboy.

    What makes you think Intel's CPU-GPU integration won't be as fabulous as their IMC or quad-core components? Intel doesn't need "significant innovations" (nor does AMD), they just need higher performance, lower power, and lower cost, which is exactly what they have.

    Innovations only exist to serve those aspects.

    Wrong.

    AMD64 (the instruction set) isn't about "more performance". Virtualization isn't about "more performance". Hardware no-execute flags aren't about "more performance". SATA's hot-plug ability isn't about "more performance".

    Your statement shows the kind of lack of vision that brought us the Pentium 4.

    I for one am far more excited about technology that allows me to do something new or different than "technology" that simply lets me do the same stuff faster. 99% of CPU cycles in the planet go unused anyway.

    Given the overall tone of your reply, the criticism of the article as "fan-boyish" is, really, the pot calling the kettle black.
  • Visual - Thursday, June 5, 2008 - link

    so you agree as well? yeah, me too.
    they are both black. they are both fanboys :)
  • zsdersw - Thursday, June 5, 2008 - link

    I've said nothing about agreeing with anything. What I have said, though, is that a fanboy calling someone else a fanboy is perhaps not indicative of any objective truth.

    It will be a great day when I can read any CPU discussion without the word fanboy in it.

    The close up of the chip has waaaaaay to much thermal compound on it.

    Is it just me or is the first pic of the Intel roadmap rather... phallic?
