One of the most attractive qualities of AMD's GCN architecture is its alacrity in compute-optimized applications, particularly now that we've seen Nvidia go the other direction with its Kepler design. The Mars- and Venus-based Radeon HD 8000M-based parts employ the same GCN pedigree, and AMD is adamant that they share similar advantages general-purpose applications able to exploit OpenCL.
So, our plan was to run a handful of synthetic tests, WinZip 17, our OpenCL-enabled Photoshop CS6 benchmark, and the Wireless Security Auditor. Testing hit a snare when we discovered certain applications returned OpenCL initialization errors. More than likely, this is a driver issue, and although AMD wasn't able to book the lab time to confirm, this is a preview, after all. Naturally, we expect these tests to run by the time Radeon HD 8000M-series hardware ships.

Although the real-world tests wouldn't complete for us, the synthetics did, strangely enough. In both LuxMark and CLBenchmark, our Core i5-2500K managed to turn back better benchmark results than the Radeon HD 7670M. But the 8790M blows them both out of the water. Particularly on mainstream 15" notebooks with much less potent CPUs than our 95 W Core i5, that could translate to a significant speed-up in OpenCL-optimized applications.

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.
