In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 MSI OC 2GB Edition are massively better than the AMD FireStream 9170.

The GTX 660 has a 206 MHz higher core clock speed and 64 more Texture Mapping Units than the FireStream 9170. This results in the GTX 660 providing 67.7 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 660 has a 206 MHz higher core clock speed and 8 more Render Output Units than the FireStream 9170. This results in the GTX 660 providing 11.3 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 660 was released over three years more recently than the FireStream 9170, and so the GTX 660 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the FireStream 9170 when running the latest games.

The GeForce GTX 660 MSI OC 2GB Edition and the FireStream 9170 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 660 has 93 GB/sec greater memory bandwidth than the FireStream 9170, which means that the memory performance of the GTX 660 is massively better than the FireStream 9170.

The GeForce GTX 660 MSI OC 2GB Edition has 960 Shader Processing Units and the FireStream 9170 has 320. However, the actual shader performance of the GTX 660 is 1029 and the actual shader performance of the FireStream 9170 is 256. The GTX 660 having 773 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the FireStream 9170.

The GTX 660 transistor size technology is 27 nm (nanometers) smaller than the FireStream 9170. This means that the GTX 660 is expected to run slightly cooler and achieve higher clock frequencies than the FireStream 9170.

The FireStream 9170 requires 105 Watts to run but there is no entry for the GTX 660. We would recommend a PSU with at least 500 Watts for the FireStream 9170, but we do not have a recommended PSU wattage for the GTX 660.

GPU Mini Review

Mini ReviewGeForce GTX 660 MSI OC 2GB Edition is a special edition of GeForce GTX 660.
The new features include the Propeller Blade Technology solution which generates 20% more airflow than traditional fan design, according to MSI.
In terms of overclocking, the base-clock was increased from 980MHz to 1006MHz and the boost clock can now reach 1072MHz, instead of 1033MHz. The memory clock was left untouched.
The overclocking is therefore somewhat significant and the performance boost is around 5% when compared to the standard GeForce GTX 660.
AMD FireStream stream processors deliver all of the parallel processing power of the GPU to compute-intensive applications for scientists, engineers and consumers. Using up to 500 GFLOPS developers can dramatically increase the performance of their data parallel task applications.
