In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 Ti 448 EVGA Classified Ultra Edition are noticeably better than the Nvidia GeForce GTX 460 PNY 1GB OC Edition.

The GTX 560 Ti has a 45 MHz higher core clock speed and 8 more Texture Mapping Units than the GTX 460. This results in the GTX 560 Ti providing 9 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 560 Ti has a 45 MHz higher core clock speed than the GTX 460 and the same number of Render Output Units. This results in the GTX 560 Ti providing 1.4 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 560 Ti was released over a year more recently than the GTX 460, and so the GTX 560 Ti is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 460.

The GTX 560 Ti has 256 MB more video memory than the GTX 460, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 560 Ti also has superior memory performance overall.

The GTX 560 Ti has 6.4 GB/sec greater memory bandwidth than the GTX 460, which means that the memory performance of the GTX 560 Ti is marginally better than the GTX 460.

The GeForce GTX 560 Ti 448 EVGA Classified Ultra Edition has 448 Shader Processing Units and the GeForce GTX 460 PNY 1GB OC Edition has 336. However, the actual shader performance of the GTX 560 Ti is 726 and the actual shader performance of the GTX 460 is 514. The GTX 560 Ti having 212 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 560 Ti delivers a slightly smoother and more efficient experience when processing graphical data than the GTX 460.

The GeForce GTX 560 Ti 448 EVGA Classified Ultra Edition requires 210 Watts to run but there is no entry for the GeForce GTX 460 PNY 1GB OC Edition. We would recommend a PSU with at least 550 Watts for the GTX 560 Ti and a PSU with at least 450 Watts for the GTX 460. The GTX 560 Ti has been recommended a PSU with 100 Watts more than the GTX 460. The difference is significant enough that the GTX 560 Ti may have an adverse affect on your yearly electricity bills in comparison to the GTX 460.
