In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 650 Ti Zotac 2GB Edition are marginally better than the Nvidia GeForce GTX 465.

The GTX 650 Ti has a 334 MHz higher core clock speed and 20 more Texture Mapping Units than the GeForce GTX 465. This results in the GTX 650 Ti providing 33.5 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 650 Ti has a 334 MHz higher core clock speed than the GeForce GTX 465, but the GeForce GTX 465 has 16 more Render Output Units than the GTX 650 Ti. As a result, the GeForce GTX 465 exhibits a 4.3 GPixel/s better Pixel Fill Rate than the GTX 650 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 650 Ti was released over a year more recently than the GeForce GTX 465, and so the GTX 650 Ti is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 465.

The GTX 650 Ti has 1024 MB more video memory than the GeForce GTX 465, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce GTX 465 has 16.3 GB/sec greater memory bandwidth than the GTX 650 Ti, which means that the memory performance of the GeForce GTX 465 is slightly better than the GTX 650 Ti.

The GeForce GTX 650 Ti Zotac 2GB Edition has 768 Shader Processing Units and the GeForce GTX 465 has 352. However, the actual shader performance of the GTX 650 Ti is 723 and the actual shader performance of the GeForce GTX 465 is 427. The GTX 650 Ti having 296 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 650 Ti delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GTX 465.

The GTX 650 Ti transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 465. This means that the GTX 650 Ti is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 465. While they exhibit similar graphical performance, the GTX 650 Ti should consume less power than the GeForce GTX 465.

The GeForce GTX 465 requires 200 Watts to run but there is no entry for the GTX 650 Ti. We would recommend a PSU with at least 450 Watts for the GTX 650 Ti and a PSU with at least 550 Watts for the GeForce GTX 465. The GeForce GTX 465 has been recommended a PSU with 100 Watts more than the GTX 650 Ti. The difference is significant enough that the GeForce GTX 465 may have an adverse affect on your yearly electricity bills in comparison to the GTX 650 Ti.
