    Re: News - A peek at Intel Core M tablet performance (14nm Broadwell)

    This is the actual benchmark run by an Intel employee on a Core M tablet:

    https://www.youtube.com/watch?v=FIKp...ature=youtu.be

    You might notice something weird about the benchmark run,especially consider it does not appear to be edited.

    Did Hexus see the same??

    Edit!!

    Supposedly that mode is run off screen - but did anyone actual see any ACTUAL graphics being rendered and if not is there any chance of you checking it out.

    Re: News - A peek at Intel Core M tablet performance (14nm Broadwell)

    So are we likely to start seeing tablets with full fat versions of windows? Including the same sort of connectivity e.g. external hdd's, mouse, keyboard, USB sticks etc?

    Some posters over on Anandtech forums noticed some interesting points.

    Quote Originally Posted by Hans de Vries
    Intel's Fastest Processor Ever.....and the Burst Mode Trick.

    The tiny "4.5W" Core M seemingly humiliates the previous record holders,
    including the Core i7 4790 Devil's Canyon running at a burst speed of 4.4GHz.








    I guess we will see many claim that Intel's new 14nm process is now 20
    times more power efficient as Intel's 22nm process or similar wild claims.
    (Even though Intel itself never made such outrageous claims of course)


    Those who know how Intel's Burst Mode work will understand how you
    can produce these kind of miraculous benchmark result. They will wonder
    instead if the new F-stepping can now officially be boosted to 4+GHz
    for very short periods of time.

    Here's explained how it works:




    The figure at the bottom right with the three blue spikes explains it all.
    The blue spikes mean that the processor is running at maximum frequency
    while during the intervals the processor is basically halted.

    Say with a single active core Broadwell at 14nm, running a 4+GHz requires
    ~18 Watt (would be very good!).

    A power dissipation of 4.5 Watt would mean that the processor is bursting
    at maximum frequency during 25% of the time and idle during 75% of the
    time to cool down.

    You can't measure this at the outside of the package because the on-
    package voltage regulators and capacitors take care of the large power
    and current spikes. From the outside you only see a processor using
    4.5 Watt.

    The benchmark can't see this either. It measures the "process-time"
    when the processor is active and running at maximum frequency.
    The benchmark doesn't measure the time when the processor is idle
    and cooling down. Therefor you get a benchmark result as if the
    processor is running always at maximum burst frequency.


    Hans.
    There is also the problem of whether the sw stack is also helping inflate scores over existing reviews too.

    The heatsink of the reference tablet is massive.

    I think we need some third party reviews first of production Core M tablets first - it looks a decent performing SOC,but I would rather see realworld performance first.

    Erm, I thought we already had those - at least as a "convertible" like the Asus T100.
    PS My three-year old Android-toting TF101 tablet (bought from Comet - remember them?) supports USB hdds and sticks and I've tried it (successfully) with a Logitech wireless USB keyboard. Downside is that you need to have it docked to get more than one USB port.
    Using a 12.5in screen with a 2,560x1,440 resolution, the 670g tablet is 7.4mm thin.
    Think you mean "7.4mm thick", as we talk about the "thickness" of something, not "thinness". Unless, of course, you're an American, in which case there's no hope for you...

    Be interesting when these are actually in devices to get real world results. These look very skewed!

    You can already get full fat Windows 8 tablets such as the Dell Venue 8 Pro.
    It's got a mini USB port, so can use all your normal usb devices, attach a hub for expansion.
    (Just needs an OTG cable, couple of pound on amazon/ebay)

    The only trouble with the Venue 8 Pro is the USB port is also used for charging and it takes some messing to get charging+usb devices to work at the same time. Otherwise its one or the other.

    I've used several of these in work, and very good unit for the price! (About £180)

    I didn't realise there were full fat windows tabs around yet- I will have a look around and see what's available. I always find with android you have to fiddle around to much to get any connectivity and even then whatever you have plugged in stops working after a while as if its gone to sleep or something.

    Re: News - A peek at Intel Core M tablet performance (14nm Broadwell)

    There are loads of full fat Windows tablets around - ebuyer are showing about 20 options (although some of those will be variants of the same tabs). The Microsoft Surface is a full Windows tab (that's the Surface/Surface 2/Surface 3, not the Surface RT, obviously). They start from under £200. Larger ones can have full sized USB ports. If a full Windows tablet is what you're after, you shouldn't have too much trouble finding one.

    I wonder how long it can actually run inside the 4.5w envelope before it's savagely thermally throttled.

    It would be interesting to see how it performs with longer term benchmarks so we could see a more real worth performance for gaming.

    Anyone got any data?

    Look at my post - there seems to be a burst mode which helps in benchmarks and the reference tablet looks to have a mahoosive heatsink.
