In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 465 are significantly better than the AMD Radeon HD 7750 Sapphire 2GB DDR3 Edition.

The HD 7750 has a 193 MHz higher core clock speed than the GeForce GTX 465, but the GeForce GTX 465 has 12 more Texture Mapping Units than the HD 7750. As a result, the GeForce GTX 465 exhibits a 1.1 GTexel/s better Texture Fill Rate than the HD 7750. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7750 has a 193 MHz higher core clock speed than the GeForce GTX 465, but the GeForce GTX 465 has 16 more Render Output Units than the HD 7750. As a result, the GeForce GTX 465 exhibits a 6.6 GPixel/s better Pixel Fill Rate than the HD 7750. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7750 was released over a year more recently than the GeForce GTX 465, and so the HD 7750 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 HD 7750 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, overall, the GeForce GTX 465 has superior memory performance.

The GeForce GTX 465 has 77.1 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the GeForce GTX 465 is much better than the HD 7750.

The Radeon HD 7750 Sapphire 2GB DDR3 Edition has 512 Shader Processing Units and the GeForce GTX 465 has 352. However, the actual shader performance of the HD 7750 is 348 and the actual shader performance of the GeForce GTX 465 is 427. The GeForce GTX 465 having 79 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 465 delivers a significantly smoother and more efficient experience when processing graphical data than the HD 7750.

The HD 7750 transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 465. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 465.

The GeForce GTX 465 requires 200 Watts to run but there is no entry for the HD 7750. We would recommend a PSU with at least 400 Watts for the HD 7750 and a PSU with at least 550 Watts for the GeForce GTX 465. The GeForce GTX 465 has been recommended a PSU with 150 Watts more than the HD 7750. The difference is significant enough that the GeForce GTX 465 may have an adverse affect on your yearly electricity bills in comparison to the HD 7750.
