In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti Zotac AMP Extreme Edition are very slightly better than the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition.

The R9 270X has a 2 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 35 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 2 MHz higher core clock speed and 8 more Render Output Units than the GTX 660 Ti. This results in the R9 270X providing 8.8 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 Radeon R9 270X Sapphire Toxic 2GB OC Edition and the GeForce GTX 660 Ti Zotac AMP Extreme 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 33.4 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 Toxic 2GB OC Edition has 1280 Shader Processing Units and the GeForce GTX 660 Ti Zotac AMP Extreme Edition has 1344. However, the actual shader performance of the R9 270X is 1251 and the actual shader performance of the GTX 660 Ti is 1581. The GTX 660 Ti having 330 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 Toxic 2GB OC Edition requires 180 Watts to run but there is no entry for the GeForce GTX 660 Ti Zotac AMP Extreme Edition. We would recommend a PSU with at least 500 Watts for the R9 270X.

GPU Mini Review

Mini ReviewRadeon 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.
GeForce GTX 660 Ti Zotac AMP Extreme Edition is Zotac's push forward on GeForce GTX 660 Ti Zotac AMP Edition.
On this edition the base-clock was increased to 1098MHz and the boost clock can now reach 1176MHz. The memory clock remains the same.
The overclocking is even more extreme and benchmarks indicate its performance is almost on level with next in series - GeForce GTX 670.
