In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 265 Crossfire are very slightly better than the AMD FirePro S9150.

The FirePro S9150 and the R7 265 have the same core clock speed of 900 MHz, but the FirePro S9150 has 48 more Texture Mapping Units than the R7 265. As a result, the FirePro S9150 exhibits a 43.2 GTexel/s better Texture Fill Rate than the R7 265. 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 and the R7 265 have both the same core clock speed and the same Pixel Fill Rate. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The FirePro S9150 was released less than a year after the R7 265, 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 R7 265, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the R7 265 has superior memory performance.

The R7 265 has 38.4 GB/sec greater memory bandwidth than the FirePro S9150, which means that the memory performance of the R7 265 is noticeably better than the FirePro S9150.

The FirePro S9150 has 2816 Shader Processing Units and the Radeon R7 265 Crossfire has 2048. However, the actual shader performance of the FirePro S9150 is 2534 and the actual shader performance of the R7 265 is 1231. The FirePro S9150 having 1303 better shader performance is not particularly notable, as altogether the R7 265 performs better when taking into account other relevant data.

The FirePro S9150 requires 235 Watts to run and the Radeon R7 265 Crossfire requires 300 Watts. We would recommend a PSU with at least 650 Watts for the R7 265, but we do not have a recommended PSU wattage for the FirePro S9150. The R7 265 requires 65 Watts more than the FirePro S9150 to run. The difference is significant enough that the R7 265 may have an adverse affect on your yearly electricity bills in comparison to the FirePro S9150.
