In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 590 EVGA Classified Hydro Copper Edition are very slightly better than the AMD FirePro S9150.

The FirePro S9150 has a 270 MHz higher core clock speed and 48 more Texture Mapping Units than the GTX 590. This results in the FirePro S9150 providing 77.8 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 S9150 has a 270 MHz higher core clock speed than the GTX 590, but the GTX 590 has 32 more Render Output Units than the FirePro S9150. As a result, the GTX 590 exhibits a 2.9 GPixel/s better Pixel Fill Rate than the FirePro S9150. 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 three years more recently than the GTX 590, and so the FirePro S9150 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 590 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 13312 MB more video memory than the GTX 590, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GTX 590 has 11.8 GB/sec greater memory bandwidth than the FirePro S9150, which means that the memory performance of the GTX 590 is slightly better than the FirePro S9150.

The FirePro S9150 has 2816 Shader Processing Units and the GeForce GTX 590 EVGA Classified Hydro Copper Edition has 1024. However, the actual shader performance of the FirePro S9150 is 2534 and the actual shader performance of the GTX 590 is 1290. The FirePro S9150 having 1244 better shader performance and an altogether better performance when taking into account other relevant data means that the FirePro S9150 delivers a marginally smoother and more efficient experience when processing graphical data than the GTX 590.

The FirePro S9150 transistor size technology is 12 nm (nanometers) smaller than the GTX 590. This means that the FirePro S9150 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 590.

The FirePro S9150 requires 235 Watts to run and the GeForce GTX 590 EVGA Classified Hydro Copper Edition requires 365 Watts. We would recommend a PSU with at least 700 Watts for the GTX 590, but we do not have a recommended PSU wattage for the FirePro S9150. The GTX 590 requires 130 Watts more than the FirePro S9150 to run. The difference is significant enough that the GTX 590 may have an adverse affect on your yearly electricity bills in comparison to the FirePro S9150.
