In terms of overall gaming performance, the graphical capabilities of the AMD FirePro S9150 are massively better than the AMD FireStream 9370.

The FirePro S9150 was released over three years more recently than the FireStream 9370, 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 FireStream 9370 when running the latest games.

The FirePro S9150 has 12288 MB more video memory than the FireStream 9370, 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 166.4 GB/sec greater memory bandwidth than the FireStream 9370, which means that the memory performance of the FirePro S9150 is massively better than the FireStream 9370.

The FirePro S9150 has 2816 Shader Processing Units and the FireStream 9370 has 1600. However, the actual shader performance of the FirePro S9150 is 2534 and the actual shader performance of the FireStream 9370 is 858. The FirePro S9150 having 1676 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 FireStream 9370.

The FirePro S9150 requires 235 Watts to run and the FireStream 9370 requires 225 Watts. The FirePro S9150 requires 10 Watts more than the FireStream 9370 to run. The difference is not significant enough for the FirePro S9150 to have a noticeably larger impact on your yearly electricity bills than the FireStream 9370.
