In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X PowerColor Devil Edition are very slightly better than the AMD Radeon HD 7870 PCS+ Vortex II Edition.

The R9 270X and the HD 7870 have both the same core clock speed and the same Texture Fill Rate. 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 and the HD 7870 have both the same core clock speed and the same Pixel Fill Rate. 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 7870, 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 7870.

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 Radeon R9 270X PowerColor Devil Edition and the Radeon HD 7870 PCS+ Vortex II 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 19.2 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the R9 270X is slightly better than the HD 7870.

Both the Radeon R9 270X PowerColor Devil Edition and the Radeon HD 7870 PCS+ Vortex II Edition have 1280 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the R9 270X is 1284 and by the HD 7870 is 1251. Knowing that the shader performance of the R9 270X is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon R9 270X PowerColor Devil Edition requires 180 Watts to run but there is no entry for the Radeon HD 7870 PCS+ Vortex II Edition. We would recommend a PSU with at least 500 Watts for the R9 270X and a PSU with at least 500 Watts for the HD 7870. 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 R9 270X PowerColor Devil Edition is a special edition of the high-end Radeon R9 270X.
This edition comes overclocked out of the box in the central unit that was increased from 1000MHz to 1150MHz, while the Boost clock is now of 1180MHz.
Benchmarks indicate a 4% performance boost over the standard edition and so this card should perform slightly better than Radeon HD 7950 Boost Edition.
Radeon HD 7870 PCS+ Vortex II Edition is a special edition of Radeon HD 7870.
This is one of today's most powerful editions of the reference as it features increases in both the core and memory clocks that went from 1000MHz to 1150MHz and from 1200MHz to 1250MHz.
Benchmarks indicate the performance boost is quite extreme and around 8% when compared to the reference Radeon HD 7870.
