In terms of overall gaming performance, the graphical capabilities of the AMD FirePro S9150 are massively better than the Nvidia GeForce GTX 650 Ti DirectCU II 1GB Edition.

The GTX 650 Ti has a 28 MHz higher core clock speed than the FirePro S9150, but the FirePro S9150 has 112 more Texture Mapping Units than the GTX 650 Ti. As a result, the FirePro S9150 exhibits a 99 GTexel/s better Texture Fill Rate than the GTX 650 Ti. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 650 Ti has a 28 MHz higher core clock speed than the FirePro S9150, but the FirePro S9150 has 48 more Render Output Units than the GTX 650 Ti. As a result, the FirePro S9150 exhibits a 42.8 GPixel/s better Pixel Fill Rate than the GTX 650 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The FirePro S9150 was released over a year more recently than the GTX 650 Ti, and so the FirePro S9150 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 650 Ti.

The FirePro S9150 has 15360 MB more video memory than the GTX 650 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the FirePro S9150 also has superior memory performance overall.

The FirePro S9150 has 233.6 GB/sec greater memory bandwidth than the GTX 650 Ti, which means that the memory performance of the FirePro S9150 is massively better than the GTX 650 Ti.

The FirePro S9150 has 2816 Shader Processing Units and the GeForce GTX 650 Ti DirectCU II 1GB Edition has 768. However, the actual shader performance of the FirePro S9150 is 2534 and the actual shader performance of the GTX 650 Ti is 713. The FirePro S9150 having 1821 better shader performance and an altogether better performance when taking into account other relevant data means that the FirePro S9150 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 650 Ti.

The FirePro S9150 requires 235 Watts to run and the GeForce GTX 650 Ti DirectCU II 1GB Edition requires 150 Watts. The FirePro S9150 requires 85 Watts more than the GTX 650 Ti to run. The difference is significant enough that the FirePro S9150 may have an adverse affect on your yearly electricity bills in comparison to the GTX 650 Ti.
