In terms of overall gaming performance, the graphical capabilities of the AMD FirePro S9150 are massively better than the AMD Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition.

The HD 4890 has a 100 MHz higher core clock speed than the FirePro S9150, but the FirePro S9150 has 136 more Texture Mapping Units than the HD 4890. As a result, the FirePro S9150 exhibits a 118.4 GTexel/s better Texture Fill Rate than the HD 4890. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 4890 has a 100 MHz higher core clock speed than the FirePro S9150, but the FirePro S9150 has 48 more Render Output Units than the HD 4890. As a result, the FirePro S9150 exhibits a 41.6 GPixel/s better Pixel Fill Rate than the HD 4890. 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 HD 4890, 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 HD 4890 when running the latest games.

The FirePro S9150 has 15360 MB more video memory than the HD 4890, 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 185.6 GB/sec greater memory bandwidth than the HD 4890, which means that the memory performance of the FirePro S9150 is massively better than the HD 4890.

The Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition has 800 Shader Processing Units and the FirePro S9150 has 2816. However, the actual shader performance of the HD 4890 is 560 and the actual shader performance of the FirePro S9150 is 2534. The FirePro S9150 having 1974 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 4890.

The FirePro S9150 transistor size technology is 27 nm (nanometers) smaller than the HD 4890. This means that the FirePro S9150 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4890.

The Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition requires 190 Watts to run and the FirePro S9150 requires 235 Watts. We would recommend a PSU with at least 500 Watts for the HD 4890. The FirePro S9150 requires 45 Watts more than the HD 4890 to run. The difference is significant enough that the FirePro S9150 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 4890.
