In terms of overall gaming performance, the graphical capabilities of the AMD FirePro S9150 are massively better than the AMD Radeon HD 7770 Sapphire GHz OC Edition.

The HD 7770 has a 250 MHz higher core clock speed than the FirePro S9150, but the FirePro S9150 has 136 more Texture Mapping Units than the HD 7770. As a result, the FirePro S9150 exhibits a 112.4 GTexel/s better Texture Fill Rate than the HD 7770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7770 has a 250 MHz higher core clock speed than the FirePro S9150, but the FirePro S9150 has 48 more Render Output Units than the HD 7770. As a result, the FirePro S9150 exhibits a 39.2 GPixel/s better Pixel Fill Rate than the HD 7770. 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 HD 7770, 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 HD 7770.

The FirePro S9150 has 15360 MB more video memory than the HD 7770, 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 240 GB/sec greater memory bandwidth than the HD 7770, which means that the memory performance of the FirePro S9150 is massively better than the HD 7770.

The FirePro S9150 has 2816 Shader Processing Units and the Radeon HD 7770 Sapphire GHz OC Edition has 640. However, the actual shader performance of the FirePro S9150 is 2534 and the actual shader performance of the HD 7770 is 626. The FirePro S9150 having 1908 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 HD 7770.

The FirePro S9150 requires 235 Watts to run and the Radeon HD 7770 Sapphire GHz OC Edition requires 80 Watts. We would recommend a PSU with at least 450 Watts for the HD 7770, but we do not have a recommended PSU wattage for the FirePro S9150. The FirePro S9150 requires 155 Watts more than the HD 7770 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 HD 7770.
