Test Setup And Benchmarks
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).

Wow, can't say I expected to see any 8000 series/700 series benchmarks for at least a few months. Looks prettyimpressive for a mobile GPU, can't wait to see what the high end mobile and desktop cards can do.Reply
Sometimes I wonder why instead of CFing or SLIing two high end mobile GPUs, a desktop GPU would've achieved the same performance but without the stuttering or driver issues.Reply
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).
Also, I'm interested to see if the MxM cards of the 8000s are available for retail purchase. I'd like to buy a 15" laptop that supports MxM and is on sale, and swap out the weak GPU.Reply
Second review I have seen that uses this module method. Interesting way of doing it. Thanks Toms and AMD.Reply
Nice preview, Aku and AMD.Reply
Though i suspect you and Chris already have large 'hints' about the HD8000 series performance, but under NDA.
looks like the value brand hit the end of the line with the 7000m series and id expect that with the APU's becoming the standard now for value graphics.Reply

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.
If the 7970M uses two 78XX, why not use a highly binned and undervolted 79XX? Again, better driver stability, more supports from games, more consistent performance scaling, and less micro-stuttering.Reply
