In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 Sapphire OC 3GB 950MHz Edition are marginally better than the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition.

The R9 270X has a 150 MHz higher core clock speed than the HD 7950, but the HD 7950 has 32 more Texture Mapping Units than the R9 270X. As a result, the HD 7950 exhibits a 18.4 GTexel/s better Texture Fill Rate than the R9 270X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R9 270X has a 150 MHz higher core clock speed than the HD 7950 and the same number of Render Output Units. This results in the R9 270X providing 4.8 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 R9 270X was released over a year more recently than the HD 7950, and so the R9 270X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7950.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The HD 7950 has 1024 MB more video memory than the R9 270X, 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 48 GB/sec greater memory bandwidth than the R9 270X, which means that the memory performance of the HD 7950 is noticeably better than the R9 270X.

The Radeon HD 7950 Sapphire OC 3GB 950MHz Edition has 1792 Shader Processing Units and the Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280. However, the actual shader performance of the HD 7950 is 1447 and the actual shader performance of the R9 270X is 1251. The HD 7950 having 196 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a significantly smoother and more efficient experience when processing graphical data than the R9 270X.

The Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 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 500 Watts for the R9 270X. 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 7950 Sapphire OC 3GB 950MHz Edition is a special edition of the Radeon HD 7950. See the page of the standard edition to know more about it.
The new features include a core-clock raise from 800MHz to 960MHz. A new cooling system with dual-extractor technology which is more effective and quieter is also featured.
The performance boost is around 7% when compared to standard Radeon HD 7950.
Radeon R9 270X Sapphire Toxic 2GB OC Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling system called "Tri-X", which reduces the card's temperature under load, significantly and comes overclocked out of the box in the central unit that was increased from 1000MHz to 1100MHz, while the Boost clock is now of 1150MHz. Also, the operating memory clock is now of 1500MHz.
Benchmarks indicate a 5% performance boost over the standard edition and so this card will surpass a Radeon HD 7950.
