In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1660 EVGA XC Ultra Gaming 6GB are significantly better than the AMD FirePro S9150.

The GTX 1660 has a 630 MHz higher core clock speed than the FirePro S9150, but the FirePro S9150 has 88 more Texture Mapping Units than the GTX 1660. As a result, the FirePro S9150 exhibits a 23.8 GTexel/s better Texture Fill Rate than the GTX 1660. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 1660 has a 630 MHz higher core clock speed but 16 fewer Render Output Units than the FirePro S9150. The lower ROP count doesn't matter, though, as altogether the GTX 1660 manages to provide 15.8 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 1660 was released over three years more recently than the FirePro S9150, and so the GTX 1660 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the FirePro S9150 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 10240 MB more video memory than the GTX 1660, 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 127.9 GB/sec greater memory bandwidth than the GTX 1660, which means that the memory performance of the FirePro S9150 is massively better than the GTX 1660.

The GeForce GTX 1660 EVGA XC Ultra Gaming 6GB has 1408 Shader Processing Units and the FirePro S9150 has 2816. However, the actual shader performance of the GTX 1660 is 2598 and the actual shader performance of the FirePro S9150 is 2534. The GTX 1660 having 64 better shader performance is not particularly notable, as altogether the FirePro S9150 performs better when taking into account other relevant data.

The GTX 1660 transistor size technology is 16 nm (nanometers) smaller than the FirePro S9150. This means that the GTX 1660 is expected to run slightly cooler and achieve higher clock frequencies than the FirePro S9150.

The GeForce GTX 1660 EVGA XC Ultra Gaming 6GB requires 160 Watts to run and the FirePro S9150 requires 235 Watts. We would recommend a PSU with at least 500 Watts for the GTX 1660. The FirePro S9150 requires 75 Watts more than the GTX 1660 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 1660.
