In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 675M SLI are massively better than the AMD Radeon HD 7520G + HD 7670M Dual.

The HD 7520G was released less than a year after the GTX 675M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 675M has 4096 MB video memory, but the HD 7520G does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce GTX 675M SLI has 768 Shader Processing Units and the Radeon HD 7520G + HD 7670M Dual has 736. However, the actual shader performance of the GTX 675M is 952 and the actual shader performance of the HD 7520G is 482. The GTX 675M having 470 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 675M delivers a massively smoother and more efficient experience when processing graphical data than the HD 7520G.

The GeForce GTX 675M SLI requires 200 Watts to run but there is no entry for the Radeon HD 7520G + HD 7670M Dual.

GPU Mini Review

Mini ReviewGeForce GTX 675M SLI is a solution of two GeForce GTX 675M put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 675M 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, about 35% better than a single GeForce GTX 675M 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 GTX 675M.
Even the most demanding games will run at the highest settings.
Radeon HD 7520G + HD 7670M Dual is a combination of a Radeon 7520G (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 is worse than a single Radeon HD 7670M performing by itself. This might be due to poor driver support.
