In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6950M are significantly better than the Nvidia GeForce 920M 2GB.

The Radeon HD 6950M has a 5 MHz higher core clock speed and 16 more Texture Mapping Units than the GeForce 920M 2GB. This results in the Radeon HD 6950M providing 9.4 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon HD 6950M has a 5 MHz higher core clock speed and 24 more Render Output Units than the GeForce 920M 2GB. This results in the Radeon HD 6950M providing 14 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce 920M 2GB was released over three years more recently than the Radeon HD 6950M, and so the GeForce 920M 2GB is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 6950M when running the latest games.

The GeForce 920M 2GB has 1024 MB more video memory than the Radeon HD 6950M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the Radeon HD 6950M has superior memory performance.

The Radeon HD 6950M has 100.8 GB/sec greater memory bandwidth than the GeForce 920M 2GB, which means that the memory performance of the Radeon HD 6950M is massively better than the GeForce 920M 2GB.

The GeForce 920M 2GB has 384 Shader Processing Units and the Radeon HD 6950M has 960. However, the actual shader performance of the GeForce 920M 2GB is 366 and the actual shader performance of the Radeon HD 6950M is 278. The GeForce 920M 2GB having 88 better shader performance is not particularly notable, as altogether the Radeon HD 6950M performs better when taking into account other relevant data.

The GeForce 920M 2GB transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 6950M. This means that the GeForce 920M 2GB is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6950M.

The GeForce 920M 2GB requires 25 Watts to run and the Radeon HD 6950M requires 50 Watts. The Radeon HD 6950M requires 25 Watts more than the GeForce 920M 2GB to run. The difference is not significant enough for the Radeon HD 6950M to have a noticeably larger impact on your yearly electricity bills than the GeForce 920M 2GB.
