In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 VTX3D 3GB Boost X-Edition are massively better than the Nvidia GeForce GTX 650 2GB.

The GTX 650 has a 178 MHz higher core clock speed than the HD 7950, but the HD 7950 has 80 more Texture Mapping Units than the GTX 650. As a result, the HD 7950 exhibits a 64.7 GTexel/s better Texture Fill Rate than the GTX 650. 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 has a 178 MHz higher core clock speed than the HD 7950, but the HD 7950 has 16 more Render Output Units than the GTX 650. As a result, the HD 7950 exhibits a 11.3 GPixel/s better Pixel Fill Rate than the GTX 650. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 650 was released less than a year after the HD 7950, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 7950 has 1024 MB more video memory than the GTX 650, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7950 also has superior memory performance overall.

The HD 7950 has 160 GB/sec greater memory bandwidth than the GTX 650, which means that the memory performance of the HD 7950 is massively better than the GTX 650.

The Radeon HD 7950 VTX3D 3GB Boost X-Edition has 1792 Shader Processing Units and the GeForce GTX 650 2GB has 384. However, the actual shader performance of the HD 7950 is 1417 and the actual shader performance of the GTX 650 is 406. The HD 7950 having 1011 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 650.

The GeForce GTX 650 2GB requires 64 Watts to run but there is no entry for the HD 7950. We would recommend a PSU with at least 500 Watts for the HD 7950 and a PSU with at least 400 Watts for the GTX 650. The HD 7950 has been recommended a PSU with 100 Watts more than the GTX 650. The difference is significant enough that the HD 7950 may have an adverse affect on your yearly electricity bills in comparison to the GTX 650.

GPU Mini Review

Mini ReviewRadeon HD 7950 VTX3D 3GB Boost X-Edition is a special edition of the high-end Radeon HD 7950 Boost Edition.
This edition comes with a custom cooling solution and overclocking out of the box in the core-clock that was increase by 30MHz to 880MHz. Therefore, the Turbo Boost is now of 930MHz.
Expect a 1.5% performance boost when compared to the reference Radeon HD 7950 Boost Edition.
GeForce GTX 650 2GB is a fast-middle-class GPU part of the 600 Series released by NVIDIA in 2012.
This version features a frame buffer of 2GB. It's known that this GPU does not benefit in any way from a 2GB frame buffer and so this GPU's performance is on level with the 1GB variant. Check the page of the 1GB version for more information about but please note this GPU is just a fast GT 640, paired with GDDR5. Its performance is nothing like next in series - GeForce GTX 650 Ti and barely any fast than previous GTX 550 Ti.
