    Ye the bogus info about no OC and that Intel would limit it was fun. Specially after the same people got caught wrong with i7.

    AMD's saving grace, from the enthusiast point of view, is the unlocked multiplier making it easier to OC as well as gaming being more a function of GPU where they run about even.

    Still, if the rumored price is correct (~196, say retail 220-230ish), there will be some downward price pressure on the 955.

It never a good deal for the customer to have different categories they are put in; as it will cost more for them to move, and often times can backfire on the manufacturer, I'm sure than when AMD dropped S754 support, and released newer S939 CPUs, people who would have normally considered an upgrade for their CPU to a faster model, just stuck with their first purchase S754 system a while longer; If they only had S939 from the beginning then they would've made more sales over time.

    Ah and aftermarket cooling hell for S775/S1156/S1366; why did they need to make the mounting on S1156 different just use S1366 mounting holes and people can re-use their 3rd party cooling over and over

    LGA1156 supports 2 x8 slots by splitting the x16. So LGA1366 is more for those people with 3 cards...

    And before we get into a performance discussion about splitting it. Its no different than having a X2/GX2 card on x16.

    oh... wow... did they update it? i could swear it wasnt there before...

    impressive how well it performs even at 2.13gh!

    .


    your next argument will be what? "it's more for people with N cards"
    who cares about the cards; splitting up a generation with two different sockets is: for the customer, pure and simple.

    It was there from the beginning, BUT, the 2.13 GHz and the X4 isn't present in every benchmark.

    What about turbo impact?

    If anandtech estimate is correct http://anandtech.com/cpuchipsets/sho...spx?i=3570&p=4

    i5 at 2.66, is running really at ~2.93 (4 threads) and ~3.33 (1-2 threads). Or something like that, If I am not missing something...

    ... how about the news that S1366 is server hardware... theres no more splitting in generations that was always there. HPC - Server/Workstaion - Consumer - Mobile -> S1567- S1366 - S1156 - S989, before it was S604 - S771 - S775 - S478 (socket P)

    Its maximum running at 2.83ghz (166BLCK) since the ES sample is locked to 1x turbomode only. Retail can only be better.

    Why is it the X4 does just fine on both the first and third graphs but dives in the 2nd graph? Why is this? Isn't the third one more demanding?

    And this? (I suppose i7 2.66 is running with Turbo ON = ~2.93):

    they are clearly targeting it as desktop system, otherwise they would not market it as "gaming CPU" and "desktop processor"; hence it is not solely server; so not server hardware;

    With faster, intelligent, multi-core technology that applies processing power where it's needed most, new Intel® Core™ i7 processors deliver an incredible breakthrough in PC performance. They are the best desktop processors on the planet.¹

    its target for consumers, but that still doesn't change the fact that it is server hardware.

    Theres no difference between a Xeon and a i7, not on the boards and not on the cpu.

    Its was the same for skulltrail, server grade hardware marketed for consumers. i7 just covers more different cpu types.

    doesn't matter one iota that it is or isn't server hardware; they target consumers, I see in your sig you got Core i7 920, the entry level, the kind budget that would buy Core i5 if it had come out first; so now that same you has to choice between two platforms, whereas this is not good a policy; one platform / generation for consumers is best;

    LGA1366 is just an extension of Skulltrail type platform basicly. Just as 1 CPU.

    That's a good point, I always forget about Trubo (adds extra complexity)... but you are missing something from the Anand article, the engineering sample was locked at 1 step for the engineering sample.

    Unfortunately this is the sample I tested with. Thankfully it was healthy enough for me to overclock the BLCK to 166MHz, resulting in a 2.66GHz frequency. Turbo mode was still stuck at a 1x increase over the stock frequency, so final Lynnfield performance should be much better in single and dual threaded apps than what you’ll see here today.
    So even with a 166 Block with a 1x bump, Nehalem is still an impressive 20% clock for clock better on average. It is actually closer to 25-30% on a wider range of applications since I have both an i7-965 and a PIIX4-940 and have seen these type of discrepancies. If you throw SLI 295's (two cards 4 GPUs) or 4870 X2's the discrepancies grow even larger in quite a few (majority) of games.

    I know it is not something you like to think about, you are obviously a huge AMD supporter, but for the moment (and for a while longer, until at least bulldozer), AMD is playing the value card.

    Personally, I don't think it makes a huge difference ... the 940 runs everything just fine, I gravitate to the i7-965 for heavy duty video encoding/editing work though.

    I'm not sure that one platform is best for consumers (sure we don't want to see all cars using the same FIAT UNO platform /joke). I dont care how many platforms will be introduced by Intel. What really matters is a "consumer properties" of the platforms.

    Your second pass is actually the first pass for the updated x.264 bench, notice the version numbers on each of your tests.

    Considering a vast majority of folks don't even consider upgrading their systems other than the enthusiasts of course, platform choice isn't really going to be major issue. General users buying prebuilt rigs are going to buy their i5, i7 or AMx based rig and run it until the wheels fall off so to speak without ever opening the case.

    The difference I see with i7 & i5 vs s754 & s939 is that Intel released the high end platform from the start whereas AMD released the higher end platform later which left early adopter s754 users who might have wanted more performance with a limited upgrade path.
