Game Radeon R9 270X Sapphire Dual-X 4GB OC Edition GeForce GTX 660 Ti SC+ 3GB w/Backplate

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti SC+ 3GB w/Backplate are marginally better than the AMD Radeon R9 270X Sapphire Dual-X 4GB OC Edition.

The R9 270X has a 40 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 32 more Texture Mapping Units than the R9 270X. As a result, the GTX 660 Ti exhibits a 28.2 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 40 MHz higher core clock speed and 8 more Render Output Units than the GTX 660 Ti. This results in the R9 270X providing 9.1 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 GTX 660 Ti, 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 GTX 660 Ti.

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 270X has 1024 MB more video memory than the GTX 660 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 270X also has superior memory performance overall.

The R9 270X has 35 GB/sec greater memory bandwidth than the GTX 660 Ti, which means that the memory performance of the R9 270X is noticeably better than the GTX 660 Ti.

The Radeon R9 270X Sapphire Dual-X 4GB OC Edition has 1280 Shader Processing Units and the GeForce GTX 660 Ti SC+ 3GB w/Backplate has 1344. However, the actual shader performance of the R9 270X is 1164 and the actual shader performance of the GTX 660 Ti is 1423. The GTX 660 Ti having 259 better shader performance is not particularly notable, as altogether the R9 270X performs better when taking into account other relevant data.

The Radeon R9 270X Sapphire Dual-X 4GB OC Edition requires 180 Watts to run and the GeForce GTX 660 Ti SC+ 3GB w/Backplate requires 150 Watts. We would recommend a PSU with at least 500 Watts for the R9 270X and a PSU with at least 450 Watts for the GTX 660 Ti. The R9 270X requires 30 Watts more than the GTX 660 Ti to run. The difference is not significant enough for the R9 270X to have a noticeably larger impact on your yearly electricity bills than the GTX 660 Ti.

GPU Mini Review

Mini ReviewRadeon R9 270X Sapphire Dual-X 4GB OC Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling system called "Vapor-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 1020MHz, while the Boost clock is now of 1070MHz.
Furthermore, the card has twice as much memory when compared to the reference card. However, this card will not benefit from extra memory and thus such feature ends up being useless.
Expect little or no performance boost over the standard edition and exactly the same performance as "Radeon R9 270X Sapphire Dual-X 2GB OC Edition"
GeForce GTX 660 Ti SC+ 3GB w/Backplate is a special edition of GeForce GTX 660 Ti.
The new features include overclocking out of the box in which the base-clock was increased from 915MHz to 980MHz and the boost clock can now reach 1059MHz, instead of 980MHz. The memory clock was left untouched but the frame buffer was increased to 3GB which actually reduces the performance due to the 192-bit bus width not being to handle the 3GB efficiently.
The overclocking is significant but there are no benchmarks available and so this GPU's rank is predicted.
