In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6970M are significantly better than the Nvidia GeForce GT 445M v2.

The Radeon HD 6970M has a 110 MHz higher core clock speed and 24 more Texture Mapping Units than the GT 445M. This results in the Radeon HD 6970M providing 18.9 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 6970M has a 110 MHz higher core clock speed and 16 more Render Output Units than the GT 445M. This results in the Radeon HD 6970M providing 12.7 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 Radeon HD 6970M was released less than a year after the GT 445M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 6970M has 1024 MB more video memory than the GT 445M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon HD 6970M also has superior memory performance overall.

The Radeon HD 6970M has 75.2 GB/sec greater memory bandwidth than the GT 445M, which means that the memory performance of the Radeon HD 6970M is much better than the GT 445M.

The GeForce GT 445M v2 has 144 Shader Processing Units and the Radeon HD 6970M has 960. However, the actual shader performance of the GT 445M is 164 and the actual shader performance of the Radeon HD 6970M is 326. The Radeon HD 6970M having 162 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 6970M delivers a massively smoother and more efficient experience when processing graphical data than the GT 445M.

The GeForce GT 445M v2 requires 35 Watts to run and the Radeon HD 6970M requires 75 Watts. The Radeon HD 6970M requires 40 Watts more than the GT 445M to run. The difference is significant enough that the Radeon HD 6970M may have a slight adverse affect on your yearly electricity bills in comparison to the GT 445M.
