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 AMD Radeon HD 7750 MSI PMD1 OC Edition.

The HD 7950 has a 50 MHz higher core clock speed and 80 more Texture Mapping Units than the HD 7750. This results in the HD 7950 providing 72 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 HD 7950 has a 50 MHz higher core clock speed and 16 more Render Output Units than the HD 7750. This results in the HD 7950 providing 14.9 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 7950 was released less than a year after the HD 7750, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 7950 has 2048 MB more video memory than the HD 7750, 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 168 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the HD 7950 is massively better than the HD 7750.

The Radeon HD 7950 VTX3D 3GB Boost X-Edition has 1792 Shader Processing Units and the Radeon HD 7750 MSI PMD1 OC Edition has 512. However, the actual shader performance of the HD 7950 is 1417 and the actual shader performance of the HD 7750 is 361. The HD 7950 having 1056 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 HD 7750.

We would recommend a PSU with at least 500 Watts for the HD 7950.

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.
Radeon HD 7750 MSI PMD1 OC Edition is a special edition of Radeon HD 7750 that features a new cooling system called Dual Fan Thermal Design which produces more airflow than traditional single fan thermal design and provides better heat dissipation with huge heatsink as well as overclocking out of the box of the core-clock to 830MHz.
Benchmarks indicate a 1.5% performance boost when compared to the reference card.
