    Hello
    I Had my surface pro 2 replaced which had a 4300u Intel chip and revived a replacement today but device manager states its a 4200u. How much of a performance loss is there between both chipsets?

    In practice there would have to be at least a 20% difference for a perceptible difference to be detected. My rule is there must be at least 30% improvement to even consider an upgrade (for upgradeable components) and that's marginal.

    PassMark score for a 4200u is 3293 and for 4300u is 3733 for an 11.786% difference. The chips use the same Intel HD 4400 graphics with a 0.1 GHz clock rate difference.

    http://ark.intel.com/compare/76308,75459 Differences highlighted.
    There are a few management and virtualization technology differences your unlikely to ever use unless its part of a well managed enterprise or you do heavy virtualization.

    About 5% at best.

    As long as the device works without issues, I would not give it another thought between the 4200/4300. You will not see any difference for tasks really, benchmarks will be the only place where you will detect the difference and its slight. Enjoy the device :)

    It was difficult enough returning 3 >new< SP2's to get the newer chip, I can't imagine what it would be like attempting to get a replacement one. I'm hoping mine will chug along without need of replacement until the SP4 Pro's come out ;)

    Thanks for the replies.

    The replacement works fine it has better angle stylus detection than the one I returned, but my only concern is that I use VMware to run Linux for some college classes. The older chip is not as optimized for that task according to the chart. I am not sure why Microsoft does not check the cpu specs before sending them out.

    I don't think it will matter as it doesn't appear VM-W supports VT-d anyway. nor is there likely to be a noticeable difference running one or two VMs on an SSD.

    Even if it did, VT-D would be useless on a surface - which resources would you be able to allocate permanently to the guest?
