In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 460 SLI are massively better than the Nvidia GeForce GTS 150.

The GeForce GTS 150 has a 63 MHz higher core clock speed than the GTX 460, but the GTX 460 has 48 more Texture Mapping Units than the GeForce GTS 150. As a result, the GTX 460 exhibits a 28.4 GTexel/s better Texture Fill Rate than the GeForce GTS 150. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GTS 150 has a 63 MHz higher core clock speed than the GTX 460, but the GTX 460 has 48 more Render Output Units than the GeForce GTS 150. As a result, the GTX 460 exhibits a 31.4 GPixel/s better Pixel Fill Rate than the GeForce GTS 150. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 460 was released over a year more recently than the GeForce GTS 150, and so the GTX 460 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTS 150.

The GTX 460 has 1024 MB more video memory than the GeForce GTS 150, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 460 also has superior memory performance overall.

The GTX 460 has 166.4 GB/sec greater memory bandwidth than the GeForce GTS 150, which means that the memory performance of the GTX 460 is massively better than the GeForce GTS 150.

The GeForce GTX 460 SLI has 672 Shader Processing Units and the GeForce GTS 150 has 128. However, the actual shader performance of the GTX 460 is 907 and the actual shader performance of the GeForce GTS 150 is 236. The GTX 460 having 671 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 460 delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GTS 150.

The GTX 460 transistor size technology is 15 nm (nanometers) smaller than the GeForce GTS 150. This means that the GTX 460 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTS 150.

The GeForce GTX 460 SLI requires 380 Watts to run and the GeForce GTS 150 requires 141 Watts. We would recommend a PSU with at least 600 Watts for the GTX 460 and a PSU with at least 450 Watts for the GeForce GTS 150. The GTX 460 requires 239 Watts more than the GeForce GTS 150 to run. The difference is significant enough that the GTX 460 may have an adverse affect on your yearly electricity bills in comparison to the GeForce GTS 150.
