In terms of overall gaming performance, the graphical capabilities of the AMD FirePro M5100 are significantly better than the Nvidia GeForce GT 445M v2.

The FirePro M5100 has a 155 MHz higher core clock speed and 16 more Texture Mapping Units than the GT 445M. This results in the FirePro M5100 providing 15.3 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 FirePro M5100 has a 155 MHz higher core clock speed than the GT 445M and the same number of Render Output Units. This results in the FirePro M5100 providing 2.5 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 FirePro M5100 was released over three years more recently than the GT 445M, and so the FirePro M5100 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GT 445M when running the latest games.

The FirePro M5100 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 FirePro M5100 also has superior memory performance overall.

The FirePro M5100 has 32 GB/sec greater memory bandwidth than the GT 445M, which means that the memory performance of the FirePro M5100 is noticeably better than the GT 445M.

The FirePro M5100 has 640 Shader Processing Units and the GeForce GT 445M v2 has 144. However, the actual shader performance of the FirePro M5100 is 496 and the actual shader performance of the GT 445M is 164. The FirePro M5100 having 332 better shader performance and an altogether better performance when taking into account other relevant data means that the FirePro M5100 delivers a significantly smoother and more efficient experience when processing graphical data than the GT 445M.

The FirePro M5100 transistor size technology is 12 nm (nanometers) smaller than the GT 445M. This means that the FirePro M5100 is expected to run slightly cooler and achieve higher clock frequencies than the GT 445M.

The FirePro M5100 requires 50 Watts to run and the GeForce GT 445M v2 requires 35 Watts. The FirePro M5100 requires 15 Watts more than the GT 445M to run. The difference is not significant enough for the FirePro M5100 to have a noticeably larger impact on your yearly electricity bills than the GT 445M.
