In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 EVGA Classified Kingpin ACX 2.0+ 4GB Edition are significantly better than the AMD FirePro S9150.

The GTX 980 has a 404 MHz higher core clock speed but 48 fewer Texture Mapping Units than the FirePro S9150. The lower TMU count doesn't matter, though, as altogether the GTX 980 manages to provide 8.5 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 GTX 980 has a 404 MHz higher core clock speed than the FirePro S9150 and the same number of Render Output Units. This results in the GTX 980 providing 25.9 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 GTX 980 was released less than a year after the FirePro S9150, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The FirePro S9150 has 12288 MB more video memory than the GTX 980, 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 95.6 GB/sec greater memory bandwidth than the GTX 980, which means that the memory performance of the FirePro S9150 is massively better than the GTX 980.

The GeForce GTX 980 EVGA Classified Kingpin ACX 2.0+ 4GB Edition has 2048 Shader Processing Units and the FirePro S9150 has 2816. However, the actual shader performance of the GTX 980 is 3920 and the actual shader performance of the FirePro S9150 is 2534. The GTX 980 having 1386 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 980 delivers a noticeably smoother and more efficient experience when processing graphical data than the FirePro S9150.

The GeForce GTX 980 EVGA Classified Kingpin ACX 2.0+ 4GB Edition requires 165 Watts to run and the FirePro S9150 requires 235 Watts. We would recommend a PSU with at least 500 Watts for the GTX 980. The FirePro S9150 requires 70 Watts more than the GTX 980 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 980.
