In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7640G + HD 7670M Dual are marginally better than the Nvidia GeForce 9800M GT SLI.

The HD 7640G was released over three years more recently than the 9800M GT, and so the HD 7640G is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 9800M GT when running the latest games.

The 9800M GT has 1024 MB video memory, but the HD 7640G does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 9800M GT SLI has 192 Shader Processing Units and the Radeon HD 7640G + HD 7670M Dual has 736. However, the actual shader performance of the 9800M GT is 96 and the actual shader performance of the HD 7640G is 482. The HD 7640G having 386 better shader performance is not particularly notable, as altogether the 9800M GT performs better when taking into account other relevant data.

The GeForce 9800M GT SLI requires 130 Watts to run but there is no entry for the Radeon HD 7640G + HD 7670M Dual.

GPU Mini Review

Mini ReviewGeForce 9800M GT SLI is a solution of two GeForce 9800M GT put together using NVIDIA'S SLI technology.
Check the page of GeForce 9800M GT to know more about its chip.
As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, up to X% better than a single GeForce 9800M GT performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce 9800M GT.
A few demanding games will run at the highest settings with fluent frame rates (30+) but overall most games will require reduced settings to be played optimally.
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.
