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

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

The Radeon HD 6770M 2GB and the GeForce GT 550M 2GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

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

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

The Radeon HD 6770M 2GB requires 35 Watts to run and the GeForce GT 550M 2GB 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 ReviewRadeon HD 6770M 2GB is a variant of fast-middle-class Radeon HD 6770M that features a 2GB frame buffer. Check its page to know more about its performance.
This GPU does not benefit from a 2GB frame buffer and so its performance is exactly like the 1GB version.
Overview
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.
