In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270 Sapphire Dual-X 2GB OC Edition are marginally better than the Nvidia GeForce GTX 660 MSI OC 2GB Edition.

The GTX 660 has a 86 MHz higher core clock speed and the same number of Texture Mapping Units as the R9 270. This results in the GTX 660 providing 6.9 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 GTX 660 has a 86 MHz higher core clock speed than the R9 270, but the R9 270 has 8 more Render Output Units than the GTX 660. As a result, the R9 270 exhibits a 5.3 GPixel/s better Pixel Fill Rate than the GTX 660. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 270 was released over a year more recently than the GTX 660, and so the R9 270 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 660.

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 270 Sapphire Dual-X 2GB OC Edition and the GeForce GTX 660 MSI OC 2GB 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 270 has 35 GB/sec greater memory bandwidth than the GTX 660, which means that the memory performance of the R9 270 is noticeably better than the GTX 660.

The Radeon R9 270 Sapphire Dual-X 2GB OC Edition has 1280 Shader Processing Units and the GeForce GTX 660 MSI OC 2GB Edition has 960. However, the actual shader performance of the R9 270 is 1028 and the actual shader performance of the GTX 660 is 1029. The GTX 660 having 1 better shader performance is not particularly notable, as altogether the R9 270 performs better when taking into account other relevant data.

We would recommend a PSU with at least 500 Watts for the R9 270.

GPU Mini Review

Mini ReviewRadeon R9 270 Sapphire Dual-X 2GB OC Edition is a special edition of the fast-middle-class Radeon R9 270.
This edition comes with a custom cooling system called "Dual-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 900MHz to 920MHz, while the Boost clock is now of 945MHz.
Expect little or no performance boost over the standard edition.
GeForce GTX 660 MSI OC 2GB Edition is a special edition of GeForce GTX 660.
The new features include the Propeller Blade Technology solution which generates 20% more airflow than traditional fan design, according to MSI.
In terms of overclocking, the base-clock was increased from 980MHz to 1006MHz and the boost clock can now reach 1072MHz, instead of 1033MHz. The memory clock was left untouched.
The overclocking is therefore somewhat significant and the performance boost is around 5% when compared to the standard GeForce GTX 660.
