WebXPRT

I also included Principled Technologies' new HTML5/js web test suite WebXPRT in our power analysis. Like the rest of the tests, Intel already outperforms NVIDIA here but does so with lower power consumption. A big part of the advantage continues to be lower power consumption on the GPU rail, surprisingly enough.

TouchXPRT

As our first native client test, we turned to PT's TouchXPRT 2013. As there is no "run-all" functionality in the TouchXPRT benchmark, we had to present individual power curves for each benchmark. The story told here is really more of the same. On the CPU side, Intel is able to deliver better performance at lower power consumption. On the GPU side, performance is good enough for these tasks but once again, is delivered at lower power consumption.

    Idle power comparisons on a sample size of one should not count. You would think that binning makes all samples look alike but you will be surprised. Reply

    This is just so impressive...since at least the late 90's I've been wanting exactly this-an actual x86 PC in a mobile form factor. And...it's actually here.

    Heck, this Atom could go in today's CELL phones no problem (the bigger, higher end ones anyway). It's better than Vita's CPU (although granted, wasn't available at the time).

    An actual tablet that can be SMALLER than ARM tablets even, real Windows, real x86...same price. Soooo impressive!

    Granted the hardware will keep getting better and the software kinks will get worked out, but...it's actually happening!

    Very nice comparison! x86 does seem to be very power efficient! Except the Tegra 3's companion core isn't working. Compare an x86 Android tablet/phone with ARM tablet/phone. That will be more of an apple to apple comparison.

    All the guys rooting for Intel. Beware! Intel crushed AMD with Core CPUs. But when AMD lost the battle, there were no more moderately priced intel CPUs! Intel is like Apple! They always charge a premium.

    I hope Intel looses to the armada of ARM CPU designers (Samsung, nVidia, Quailcomm) just for the sake of cheap CPUs. With the world heading towards internet of everything, the last thing we need is COSTLY intel CPUs!
