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).

Though i suspect you and Chris already have large 'hints' about the HD8000 series performance, but under NDA.
And if thermal management is an issue, then the desktop GPUs could always be undervolted (but of course more expensive because of the extra step).

That's what they all say!
If you look, there is only one chip (shown on this page) which means it is not being CrossFired. I agree that 8780M would be a better name than 8790M. Andrew Ku, maybe on the front page you can clarify this?
About using desktop parts, it is my understanding that they sometimes do exactly that. Take the 7970M, which as far as I can tell, is an 78XX part (I forget which one) except the mobile chip has MUCH higher binning than the desktop 78XX.
Hell I wanted to show numbers, but I think it would be premature and possibly misleading.
They even have Haswell chips floating around their office(s), I just know it
Not because it's an ohmygodbestgameever type of game (has a few issues), but it is good for performance benchmarking.
