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

The HD 7870 has a 50 MHz higher core clock speed and the same number of Texture Mapping Units as the R9 270X. This results in the HD 7870 providing 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 HD 7870 has a 50 MHz higher core clock speed than the R9 270X and the same number of Render Output Units. This results in the HD 7870 providing 1.6 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 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 MSI Hawk 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 MSI Hawk Edition and the Radeon HD 7870 PCS+ Vortex II Edition have 1280 Shader Processing Units. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, the HD 7870 has 4 GTexel/s better Texture Fill Rate and 1.6 GPixel/s better Pixel Fill Rate, but the R9 270X has 19.2 GB/sec greater memory bandwidth. Overall, the R9 270X has slightly better performance.

The Radeon R9 270X MSI Hawk 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 MSI Hawk Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling 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.
Benchmarks indicate a 4% performance boost over the standard edition and so this card will surpass a Radeon HD 7950.
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.
