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 7720.

The HD 7950 has a 40 MHz higher core clock speed and 72 more Texture Mapping Units than the Radeon HD 7720. This results in the HD 7950 providing 65 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 40 MHz higher core clock speed than the Radeon HD 7720 and the same number of Render Output Units. This results in the HD 7950 providing 1.3 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 Radeon HD 7720 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 2048 MB more video memory than the Radeon HD 7720, 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 105.6 GB/sec greater memory bandwidth than the Radeon HD 7720, which means that the memory performance of the HD 7950 is massively better than the Radeon HD 7720.

The Radeon HD 7720 has 800 Shader Processing Units and the Radeon HD 7950 VTX3D 3GB Boost X-Edition has 1792. However, the actual shader performance of the Radeon HD 7720 is 336 and the actual shader performance of the HD 7950 is 1417. The HD 7950 having 1081 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 Radeon HD 7720.

The HD 7950 transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 7720. This means that the HD 7950 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 7720.

The Radeon HD 7720 requires 150 Watts to run but there is no entry for the Radeon HD 7950 VTX3D 3GB Boost X-Edition. We would recommend a PSU with at least 500 Watts for the Radeon HD 7720 and a PSU with at least 500 Watts for the HD 7950. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon HD 7720 is a fast-middle-class GFX that's still based on the 40nm, Terascale 2 architecture.
It's based on the Barts LE Core and offers 800 Shader Processing Units, 40 TMUs and 32 ROPs, on a 256-bit memory interface of fast GDDR5. The central unit runs at 840MHz and the memory clock operates at 1050MHz.
Therefore, it's a renamed Radeon HD 6790 and will offer exactly the same performance.
As based on the Barts LE Core, it performs better than Radeon HD 7750 (which goes against the naming) but falls behind Radeon HD 7770. It's expected to consume 150 Watt - more than Radeon HD 7750/Radeon HD 7770 and heat more, due to the higher manufacturing process. As based on the Terascale 2 architecture, it will not have nearly as much driver support as the GCN based GPUs.
Radeon 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.
