AMD Radeon HD 8790M: Next-Gen Mobile Mainstream Graphics Preview
By

Again, because the new Radeon HD 8000M-series GPUs aren't yet shipping in notebooks, we're using a desktop-oriented setup with a PCI Express interposer to preview the performance of AMD's GCN-enabled mainstream mobile graphics processors. Although we could have used an overclocked Core i7-3770K to crush the potential of a platform-oriented bottleneck, we stepped down to a Core i5-2500K instead. Though still fast, this part running at its stock settings is perhaps a better match to the performance of what you might find in a notebook (even if its 95 W TDP is way out of bounds).

    So having misnamed products in the past they now have to continue to misname parts to avoid having something named correctly clash with a prior misnamed part!
    Stupid AMD (though the green camp is no better).

    Hi Andrew,
    I'm curious why you would bother testing mobile graphics cards, and leave out the 1366x768 resolution... it's only the MOST COMMON resolution on "main stream" notebooks... who cares about 1280x720?
    Thanks
    Harison.
