Radeon HD 7640G + HD 7670M Dual Game Requirement Analysis

Radeon HD 7640G + HD 7670M Dual is a combination of a Radeon 7640G (integrated graphics) with a Radeon HD 7670M (dedicated).
This combination is called Asymmetric CrossFire and can also lead to Micro Stuttering.
Unfortunately, benchmarks indicate the performance relies a lot on driver support and is, at times, worse than a single Radeon HD 7670M performing by itself.

Can the information here be updated due to the anti micro stuttering driver updates giving it a slight boost in performance?

There are two versions of this with 1.5GB and 2.5 GB VRAM… In the latter case the dedicated GPU is a 2GB HD7670M… But performance is actually identical if not worse on the 2.5GB version…

Try with enabled Crossfire first. If gameplay is OK, then good. If not, tr disabling it. Worked for me with NFS: MW 2012

I wanna buy a laptop with this Gpu and A8 4500m CPU. Do you think it is better than a laptop with an AMD AMD® A6-3410 1.60GHz and GPU AMD Radeon HD 6755G2?

Why does it say that your graphics card is 45% better than mine but my cpu is 1% better even though they're the same?

Yeah, but the Catalyst drives aren't made well with this
I'm running on my stock drivers and they benchmarked the same as a GTX 460M
I tried using Catalyst and my performance was TERRIBLE so yeah, it's more of a driver issue

I benchmarked a few games like DMC4
and i tried using FurMark, PhysX FluildMark, and something else on oZone3D.Net
im running Driver Version 8.941.4.1000
Just saying, with the right drivers this card is actually really good
I used my friends Gtx 460m and i'm not sure what drivers he was running with his laptop

I was surprised too

They claim they have the same 3D Mark score but in terms of gaming benchmarks… nothing like GTX 460M

There, I have raised its rank. Please select it as your GPU and report the FPS you are experiencing with it. After it, I might make a final adjustment. Some GPUs on GD have been ranked based on member feedback :-)
