In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6770M are noticeably better than the Nvidia GeForce GT 550M 2GB.

The GT 550M has a 15 MHz higher core clock speed than the Radeon HD 6770M, but the Radeon HD 6770M has 8 more Texture Mapping Units than the GT 550M. As a result, the Radeon HD 6770M exhibits a 5.6 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 15 MHz higher core clock speed than the Radeon HD 6770M, but the Radeon HD 6770M has 4 more Render Output Units than the GT 550M. As a result, the Radeon HD 6770M exhibits a 2.8 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 GT 550M was released less than a year after the Radeon HD 6770M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GT 550M has 1024 MB more video memory than the Radeon HD 6770M, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The Radeon HD 6770M has 22.4 GB/sec greater memory bandwidth than the GT 550M, which means that the memory performance of the Radeon HD 6770M is slightly better than the GT 550M.

The GeForce GT 550M 2GB has 96 Shader Processing Units and the Radeon HD 6770M has 480. However, the actual shader performance of the GT 550M is 142 and the actual shader performance of the Radeon HD 6770M is 174. The Radeon HD 6770M having 32 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 6770M delivers a noticeably smoother and more efficient experience when processing graphical data than the GT 550M.

The GeForce GT 550M 2GB requires 35 Watts to run and the Radeon HD 6770M requires 35 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewOverview
GeForce GT 550M 2GB is a middle-class Mobile Graphics Card based on the first revision of the Fermi Architecture.

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.

GPU
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.

Memory
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.

Features
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.

Performance
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.
Radeon HD 6770M is a fast-middle-class GPU based on the 40nm Terrascale 2 architecture.
It's based on the Turks Core (therefore related to Radeon HD 6670) and offers 480 Shader Processing Units, 24 TMUs and 8 ROPs on a 128-bit memory interface of fast GDDR5. Its central clock runs at 725MHz and the memory clock operates at 800MHz.
Its performance is superior to both Radeon HD 6830M & Radeon HD 6850M due to being paired with fast GDDR5.
Using a 720p resolution, most of today's games are only playable at medium or high settings but with very fluent frame rates (45+).
