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.

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.

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.

[citation][nom]mayankleoboy1[/nom]Nice preview, Aku and AMD.Though i suspect you and Chris already have large 'hints' about the HD8000 series performance, but under NDA.[/citation]

In the words of Sgt. Schultz "I know nothing." =_=

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.

Interesting to see a relatively detailed preview this far ahead of launch. AMD should be doing this more - thanks to both parties. I was wondering - why not connect a power meter up and test the desktop setup? Would it be too prone to variation?

Cause it's not even final silicon. And power is always going to be a function of that and shipping clock speeds, which we don't know yet.

[citation][nom]silverblue[/nom]Very true. Just curious, though.[/citation]
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 :D

BTW good call using Hitman, hope we see it more often.

Not because it's an ohmygodbestgameever type of game (has a few issues), but it is good for performance benchmarking.

Wow thats actually quite good performance. 26 FPS in BF3 on Ultra with MSAA is actually quite good taking it from a mobile point of view. Kudos to AMD.

This is just an indication. Chips in actual notebooks would probably be clocked lower.

Looks to be a great chip. Would like to know power draw numbers but Judging by GCN and 28nm, it should be lower than the 40nm parts. Not sure because of that fan tho.

I really don't like the new naming scheme, 7800 > 8800 is confusing to the public, I know AMD did it before but this time it doesn't really seem to be needed as they are using 1 chip for 3 tiers of gpus. I think they could have kept the old naming scheme by just adjusting the numbers a little. Why have 8500, 8600, and 8700 be the same chip?
