In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 750 Zotac Thunderbolt 1GB Edition are noticeably better than the Nvidia GeForce GTX 465.

The GTX 750 has a 622 MHz higher core clock speed but 12 fewer Texture Mapping Units than the GeForce GTX 465. The lower TMU count doesn't matter, though, as altogether the GTX 750 manages to provide 12.6 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 has a 622 MHz higher core clock speed but 16 fewer Render Output Units than the GeForce GTX 465. The lower ROP count doesn't matter, though, as altogether the GTX 750 manages to provide 0.3 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 750 was released over three years more recently than the GeForce GTX 465, and so the GTX 750 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 GeForce GTX 750 Zotac Thunderbolt 1GB Edition and the GeForce GTX 465 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce GTX 465 has 16.3 GB/sec greater memory bandwidth than the GTX 750, which means that the memory performance of the GeForce GTX 465 is slightly better than the GTX 750.

The GeForce GTX 750 Zotac Thunderbolt 1GB Edition has 512 Shader Processing Units and the GeForce GTX 465 has 352. However, the actual shader performance of the GTX 750 is 912 and the actual shader performance of the GeForce GTX 465 is 427. The GTX 750 having 485 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 750 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GTX 465.

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

The GeForce GTX 750 Zotac Thunderbolt 1GB Edition requires 55 Watts to run and the GeForce GTX 465 requires 200 Watts. We would recommend a PSU with at least 300 Watts for the GTX 750 and a PSU with at least 550 Watts for the GeForce GTX 465. The GeForce GTX 465 requires 145 Watts more than the GTX 750 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.
