Intel details Broadwell, promises big power savings

  • Whereas Intel's (INTC +1.3%) 22nm Haswell CPU architecture aims to deliver at least a 1% increase in performance for every 1% increase in power draw, its 14nm Broadwell architecture shoots for a 2% performance gain for each 1% power increase.
  • Together with the gains that come from smaller transistor sizes, Broadwell's power draw is improved with the help of 15% and 10% respective drops in capacitance and minimum operating voltage, and a sizable reduction in leakage.
  • In addition, Intel has improved the power draw of its platform controller hub (integrated within CPU packages) and voltage regulator ICs, and cut the amount of extra power required by its Turbo Boost mode.
  • On the performance front, Intel is aiming for a 5%+ increase in processed instructions per CPU clock cycle relative to Haswell, and will bundle an integrated GPU that supports the latest graphics APIs, thus addressing (as noted by AnandTech) a past shortcoming.
  • Systems based on Intel's tablet/ultrabook-focused Core M Broadwell CPUs (previous) are expected this holiday season. Intel wants to offer Core M CPUs with only 3W-5W of max power draw - all Core M parts will be under 10W - and which can be used in fanless ~10" tablets that are only 8mm-10mm thick. The Surface Pro 3 (uses Core i3/i5/ii7 CPUs) is only 9.1mm thick, but also contains a fan.
  • Stabilizing PC sales have lowered the pressure Intel faces to produce a mobile breakthrough. However, Broadwell/Core M is still pivotal to Intel's attempts to grab share from ARM-based mobile CPUs by enabling converged devices that fuse PC-like performance with low power draw and mobile-friendly form factors.

    Its interesting to watch as INTC distances itself from the failed Atom brand...

    Sure they are ... That's why they just released 5 new "Moorefield" Atom SKUs with a completely new GPU and there are a whole slew of Android Atom tablets about to launch.

    note the title:
    "Moorefield, Intel’s New Smartphone Plaform Based on Atom SoC, has Secretly Begun Shipping"

     

    Wonder why INTC would "secretly" do such a thing ? Not proud of Atom's history much ?

     

    And don't hold your breath regarding Android on Atom...They've been harping about this for years now with nothing to show for it...

    trader_xx, do you think anyone is still buying your nonsense? Android on Atom is already here.

     

    This announcement is about 14nm, and Broadwell is the first on 14nm. You're not going to see a big Atom announcement until Atom moves to 14nm.

    That amusing and why do you think Intel IoT chips are branded Quarks? Obviously because they have nothing to do with Atoms!

    techy, quarks are just old Pentiums, recall they lack bit mapped graphics. That is why Intel was able to ship them quickly.

     

    I do not know the details of how Intel shrank the masks for modern fab processes.

    Quarks are just old Pentiums that cost $1 or two and will run IoT devices that don't need graphics interfaces like fans, lamps, toasters and the like. Quarks at 14nm will but Pentiums that cost less $1 and run anywhere.

    Not having to publish your real names to stand behind your comments no matter what they are is one problem with the internet. Name calling, bad manners, poor sports all with anonymity.

    I do not think discussing financial matters using your real name is wise!

    I tried using my email address and SS# once but that didn't work out too well.

     

    By the way, what's the origin of the "wdcfan" surname? It sounds like maybe Bulgarian to me.

    Atom was created to fill the low power void until the big core power is brought down to the tablet power envelop of sub 15 watts. I wouldn't say atom fail as it did it's job to keep those sockets from leaving x86 to other architecture.

    I think Atom was created so Intel could package IP units into 22nm and smaller chips without cannibalizing their Core product line. That's exactly why Intel's releasing 14nm for mobile first so they can continue to sell 22nm PC and server chips until they grab the mobile market sales they want. Why obsolete existing 22nm PC and server chips now when they can wait 3-9 months?

    zfeng, Haswell Y was already below 15 watts. Atom will continue to slot below where the Core line is at. If Broadwell Y is 4.5 watts, then Atom will come in below that (which is even with the present generation the case).

    If they can get the 14nm and new designs up in yield, this may be the biggest leap Intel has made in many years. And I suspect the following "toc" will be almost as great. If this tic and toc work, even if they take an extra year or two, Intel business should be great for five years and more, stock should at least double from here. But they are not there yet.

     

    Low power is increasingly important even for server chips, when bought and in truckloads by companies like Google and operated en mass, power consumption and cooling are big expenses, Google might happily replace all existing hardware with 14nm chips - and then again when and if the 10nm come out. Imagine the money involved. And enough to get Intel at least into the race on mobile, even if they never make a net dime off of it, just to defend the platform.

    I wonder if any of the hard-core INTC bears/skeptics use INTC processors in their PC's? I wonder if they would admit it if they did..
