In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7640G + HD 7610M Dual are noticeably better than the Nvidia GeForce GT 550M 2GB.

The GT 550M has a 290 MHz higher core clock speed than the HD 7640G, but the HD 7640G has 20 more Texture Mapping Units than the GT 550M. As a result, the HD 7640G exhibits a 4.4 GTexel/s better Texture Fill Rate than the GT 550M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 550M has a 290 MHz higher core clock speed than the HD 7640G, but the HD 7640G has 12 more Render Output Units than the GT 550M. As a result, the HD 7640G exhibits a 4.2 GPixel/s better Pixel Fill Rate than the GT 550M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7640G was released over a year more recently than the GT 550M, and so the HD 7640G is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 550M.

The GT 550M has 1024 MB more video memory than the HD 7640G, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 550M also has superior memory performance overall.

The memory bandwidth of the Radeon HD 7640G + HD 7610M Dual and the GeForce GT 550M 2GB are the same, which means the HD 7640G and the GT 550M have equal limitations when it comes to graphical data transfer.

The Radeon HD 7640G + HD 7610M Dual has 656 Shader Processing Units and the GeForce GT 550M 2GB has 96. However, the actual shader performance of the HD 7640G is 430 and the actual shader performance of the GT 550M is 142. The HD 7640G having 288 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7640G delivers a marginally smoother and more efficient experience when processing graphical data than the GT 550M.

The HD 7640G transistor size technology is 12 nm (nanometers) smaller than the GT 550M. This means that the HD 7640G is expected to run slightly cooler and achieve higher clock frequencies than the GT 550M.

The GeForce GT 550M 2GB requires 35 Watts to run but there is no entry for the HD 7640G.

GPU Mini Review

Mini ReviewRadeon HD 7640G + HD 7610M Dual is a combination of a Radeon 7640G (integrated graphics) with a Radeon HD 7610M (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 7610M performing by itself.
GeForce GT 550M 2GB is a middle-class Mobile Graphics Card based on the first revision of the Fermi Architecture.

The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

It equips a GPU Codenamed GF108 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 4 ROPs. The Central Unit is clocked at 740MHz.

The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 35W, it is suited for 15" or larger laptops.

Gaming benchmarks put its performance only slightly above a desktop GeForce GT 430.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 550M 2GB.
