In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition are massively better than the AMD Radeon HD 7750 Sapphire 2GB DDR3 Edition.

The R9 270X has a 300 MHz higher core clock speed and 48 more Texture Mapping Units than the HD 7750. This results in the R9 270X providing 62.4 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 R9 270X has a 300 MHz higher core clock speed and 16 more Render Output Units than the HD 7750. This results in the R9 270X providing 22.4 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 7750, 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 7750.

The Radeon R9 270X Sapphire Toxic 2GB OC Edition and the Radeon HD 7750 Sapphire 2GB DDR3 Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R9 270X has 166.4 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the R9 270X is massively better than the HD 7750.

The Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280 Shader Processing Units and the Radeon HD 7750 Sapphire 2GB DDR3 Edition has 512. However, the actual shader performance of the R9 270X is 1251 and the actual shader performance of the HD 7750 is 348. The R9 270X having 903 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 270X delivers a massively smoother and more efficient experience when processing graphical data than the HD 7750.

The Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts to run but there is no entry for the Radeon HD 7750 Sapphire 2GB DDR3 Edition. We would recommend a PSU with at least 500 Watts for the R9 270X and a PSU with at least 400 Watts for the HD 7750. The R9 270X has been recommended a PSU with 100 Watts more than the HD 7750. The difference is significant enough that the R9 270X may have an adverse affect on your yearly electricity bills in comparison to the HD 7750.

GPU Mini Review

Mini ReviewRadeon 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.
Radeon HD 7750 Sapphire 2GB DDR3 Edition is a special edition of the fast-middle-class Radeon HD 7750 1GB DDR3.
This version has no new features (when compared to the DDR3 version) and so it performs exactly like it.
