In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti Asus Dragon DirectCU II TOP 2GB Edition are marginally better than the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition.

The R9 270X has a 16 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 33.4 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 16 MHz higher core clock speed and 8 more Render Output Units than the GTX 660 Ti. This results in the R9 270X providing 9.2 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 less than a year after the GTX 660 Ti, and so they are likely to have similar driver support for optimizing performance when running the latest games.

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 GeForce GTX 660 Ti Asus Dragon DirectCU II TOP 2GB Edition and the Radeon R9 270X Sapphire Toxic 2GB OC 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 45.6 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 GeForce GTX 660 Ti Asus Dragon DirectCU II TOP 2GB Edition has 1344 Shader Processing Units and the Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280. However, the actual shader performance of the GTX 660 Ti is 1546 and the actual shader performance of the R9 270X is 1251. The GTX 660 Ti having 295 better shader performance is not particularly notable, as altogether the R9 270X performs better when taking into account other relevant data.

The GeForce GTX 660 Ti Asus Dragon DirectCU II TOP 2GB Edition requires 150 Watts to run and the Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts. We would recommend a PSU with at least 450 Watts for the GTX 660 Ti and a PSU with at least 500 Watts for the R9 270X. 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 ReviewOverview
GeForce GTX 660 Ti Asus Dragon DirectCU II TOP 2GB Edition is a special edition of NVIDIA's Performance GeForce GTX 660 Ti 2GB, created by Asus.

Overclock: Central Unit
The Central Unit now runs at 1085MHz, instead of 915MHz and goes up to 1150MHz, in Turbo Mode.

Overclock: Memory Clock
The Operating Memory Clock is now of 1525MHz while the Frame Buffer remains the same.

Cooling Solution
The reference NVIDIA Single-Fan Cooling System has been replaced by Asus's DirectCU thermal design which utilizes direct contact copper heatpipes so heat is dissipated efficiently, delivering a 20% cooler and vastly quieter performance than reference.

Performance
9% performance over the reference GeForce GTX 660 Ti.
Radeon 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.
