In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 280 Crossfire are significantly better than the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition.

The R9 270X has a 273 MHz higher core clock speed than the R9 280, but the R9 280 has 144 more Texture Mapping Units than the R9 270X. As a result, the R9 280 exhibits a 97.2 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 273 MHz higher core clock speed than the R9 280, but the R9 280 has 32 more Render Output Units than the R9 270X. As a result, the R9 280 exhibits a 17.7 GPixel/s better Pixel Fill Rate than the R9 270X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 280 was released less than a year after the R9 270X, and so they are likely to have similar driver support for optimizing performance when running the latest games.

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 R9 280 has 4096 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 R9 280 also has superior memory performance overall.

The R9 280 has 288 GB/sec greater memory bandwidth than the R9 270X, which means that the memory performance of the R9 280 is massively better than the R9 270X.

The Radeon R9 280 Crossfire has 3584 Shader Processing Units and the Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280. However, the actual shader performance of the R9 280 is 3344 and the actual shader performance of the R9 270X is 1251. The R9 280 having 2093 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 280 delivers a massively smoother and more efficient experience when processing graphical data than the R9 270X.

The Radeon R9 280 Crossfire requires 400 Watts to run and the Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts. We would recommend a PSU with at least 750 Watts for the R9 280 and a PSU with at least 500 Watts for the R9 270X. The R9 280 requires 220 Watts more than the R9 270X to run. The difference is significant enough that the R9 280 may have an adverse affect on your yearly electricity bills in comparison to the R9 270X.

GPU Mini Review

Mini ReviewThe Radeon R9 280 Crossfire setup of Radeon R9 280.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.
