In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 750 Ti Gigabyte Low Profile OC 2GB Edition are noticeably better than the Nvidia GeForce GTX 465.

The GTX 750 Ti has a 425 MHz higher core clock speed but 4 fewer Texture Mapping Units than the GeForce GTX 465. The lower TMU count doesn't matter, though, as altogether the GTX 750 Ti manages to provide 14.6 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 750 Ti has a 425 MHz higher core clock speed than the GeForce GTX 465, but the GeForce GTX 465 has 16 more Render Output Units than the GTX 750 Ti. As a result, the GeForce GTX 465 exhibits a 2.9 GPixel/s better Pixel Fill Rate than the GTX 750 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 750 Ti was released over three years more recently than the GeForce GTX 465, and so the GTX 750 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce GTX 465 when running the latest games.

The GTX 750 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 750 Ti, which means that the memory performance of the GeForce GTX 465 is slightly better than the GTX 750 Ti.

The GeForce GTX 750 Ti Gigabyte Low Profile OC 2GB Edition has 640 Shader Processing Units and the GeForce GTX 465 has 352. However, the actual shader performance of the GTX 750 Ti is 959 and the actual shader performance of the GeForce GTX 465 is 427. The GTX 750 Ti having 532 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 750 Ti delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GTX 465.

The GTX 750 Ti transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 465. This means that the GTX 750 Ti is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 465.

The GeForce GTX 750 Ti Gigabyte Low Profile OC 2GB Edition requires 60 Watts to run and the GeForce GTX 465 requires 200 Watts. We would recommend a PSU with at least 400 Watts for the GTX 750 Ti and a PSU with at least 550 Watts for the GeForce GTX 465. The GeForce GTX 465 requires 140 Watts more than the GTX 750 Ti to run. 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 750 Ti.
