In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750 VTX3D 1GB DDR3 Edition are massively better than the Nvidia GeForce 6800 GT.

The HD 7750 has a 450 MHz higher core clock speed and 16 more Texture Mapping Units than the GeForce 6800 GT. This results in the HD 7750 providing 20 GTexel/s better texturing performance. Neither of these GPUs support DirectX 10 or higher, so Texture Rate holds more weight than when comparing more modern GPUs.

The HD 7750 has a 450 MHz higher core clock speed than the GeForce 6800 GT and the same number of Render Output Units. This results in the HD 7750 providing 7.2 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 HD 7750 was released over three years more recently than the GeForce 6800 GT, and so the HD 7750 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 GT when running the latest games.

The HD 7750 has 768 MB more video memory than the GeForce 6800 GT, 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 6800 GT has 6.4 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the GeForce 6800 GT is marginally better than the HD 7750.

The Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512 Shader Processing Units and the GeForce 6800 GT has 16. However, the actual shader performance of the HD 7750 is 348 and the actual shader performance of the GeForce 6800 GT is 6. The HD 7750 having 342 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7750 delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce 6800 GT.

The HD 7750 transistor size technology is 102 nm (nanometers) smaller than the GeForce 6800 GT. This means that the HD 7750 is expected to run massively cooler and achieve higher clock frequencies than the GeForce 6800 GT.

The GeForce 6800 GT requires 67 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.
