Power Consumption

With no quad-core 32nm desktop parts on the market today, Sandy Bridge only needs to beat Lynnfield to be more power efficient - which it does very well:

Idle power remains unchanged, but load power is much lower at the same clock and even within the same price target.

    And the naming...OMG!

    There will be i7 processors that require three (3 !!!) different sockets! Maybe even 4 when 2011 comes. Intel can't get their naming right for quite some time now, but they've outdone themselves this time.

    Processor names really should mean something, even if AMD and Intel don't agree. It's annoying that I have to wikipedia a processor (or memorize a thousand processors) to know what it is. We are still getting quotes for three year old Opterons and Xeons (that we're using as desktops no less), those only add to the annoyance.

    What ends up happening - good for Intel bad for technology advancement - is non IT type people buying computers are buying DDR2-667 based three-year old desktop processors.

    Ummm, but Bulldozer comes with AM3-r2... Just a sketchier way of saying new MB needed.

    At least this new Intel isn't trying to BS you. Significant revisions to the architecture require different pin layouts/counts... It is inevitable with processor evolution.

    Actually, it should be AM3 compatible:

    Even if it's not, AM2/AM3 lasted quite some time.

    "At least this new Intel isn't trying to BS you. Significant revisions to the architecture require different pin layouts/counts... It is inevitable with processor evolution."

    They know in advance what they need and could design a socket to support multiple processors. And i7/i5/i3 definitely don't need different ones.

    "Even if it's not, AM2/AM3 lasted quite some time."

    Not all AM2 processors were compatible with AM2+ MB or vice versa, not all AM3 processors compatible on AM2+ MB.

    It's still 3 different sockets.

    Marketing buddy, marketing.

    By the time 1366 is replaced, it will have been on the market for 4 years.

    Eh, no its not. Bulldozer does NOT work with non-AM3+ mobos

    AMD engineers made a decision not to make it backward compatible for three reasons.

    (1) No one but enthusiasts upgrade their CPUs. People in the real world upgrade their whole computer.

    (2) Bulldozer introduces new features that won't work with existing Socket AM3 mobos. (Isn't it bloody obvious when they have to introduce a new socket specification?)

    (3) It would cost more money and delays if they were to make a backward compatible version of Bulldozer.

    As a result, they made a compromise:
    You can take your existing AM3 CPU to AM3+ mobos, while you wait for Bulldozer to arrive. BUT, you can NOT upgrade your existing AM3 based system to Bulldozer.

    Simply put...
    AM3+ CPU and AM3+ mobo = OK
    AM3 CPU and AM3+ mobo = OK
    AM3+ CPU and AM3 mobo = Sorry. No.

    So it doesn't matter if AMD "Bulldozer" or Intel "Sandy Bridge". You will need a new mobo.

    AMD seriously has their work cut out for them with Bulldozer. The lowest end Sandy Bridge processor absolutely trounced the competition. It's insane what Intel is pulling off here, especially in the integrated graphics arena. Really makes me hope Larrabee comes back as a discrete product in the next few years. Reply

    poor kid, you don't realize 2400 is not nearly lowest end. Reply

    - based on the shown roadmap, the replacement for the i5 760 is actually the i5 2500(K).

    - i7 will have even better performance with 8 MB L3 Cache and higher graphics turbo. So there is even more performance potential in the SandyBridge die that Intel could unlock for lower SKUs if needed.
