Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Radeon R9 270X and the GTX 660 Ti are equal.
The Radeon R9 270X has a 85 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 32 more Texture Mapping Units than the Radeon R9 270X. As a result, the GTX 660 Ti exhibits a 22.5 GTexel/s better Texture Fill Rate than the Radeon 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 Radeon R9 270X has a 85 MHz higher core clock speed and 8 more Render Output Units than the GTX 660 Ti. This results in the Radeon R9 270X providing 10 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 Radeon R9 270X was released over a year more recently than the GTX 660 Ti, and so the Radeon R9 270X is likely to have better driver support, meaning it will be more optimized for 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 Radeon R9 270X and the GeForce GTX 660 Ti Inno3D Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The Radeon R9 270X has 35 GB/sec greater memory bandwidth than the GTX 660 Ti, which means that the memory performance of the Radeon R9 270X is noticeably better than the GTX 660 Ti.
The Radeon R9 270X has 1280 Shader Processing Units and the GeForce GTX 660 Ti Inno3D Edition has 1344. However, the actual shader performance of the Radeon R9 270X is 1142 and the actual shader performance of the GTX 660 Ti is 1317. The GTX 660 Ti having 175 better shader performance is not particularly notable, as altogether the Radeon R9 270X performs better when taking into account other relevant data.
The Radeon R9 270X requires 180 Watts to run and the GeForce GTX 660 Ti Inno3D Edition requires 150 Watts. We would recommend a PSU with at least 500 Watts for the Radeon R9 270X and a PSU with at least 500 Watts for the GTX 660 Ti. The Radeon R9 270X requires 30 Watts more than the GTX 660 Ti to run. The difference is not significant enough for the Radeon R9 270X to have a noticeably larger impact on your yearly electricity bills than the GTX 660 Ti.
|Mini Review||Radeon R9 270X is a high-end Graphics Card based on the Curacao XT core of the Graphics Core Next Architecture. |
The Curacao XT Core has its roots on the Pitcairn XT Core used on its predecessor - Radeon HD 7870. It offers 1280 Shader Processing Units, 80 TMUs and 32 ROPs, on a 256-bit memory interface.
However and when compared to its predecessor, Radeon R9 270X offers a Boost Clock of 1050MHz, despite its central unit still running at 1000MHz. Furthermore, its operating memory clock is significantly higher and of 1400MHz, leading to extra memory bandwidth.
Benchmarks indicate its performance is almost on level with powerful Radeon HD 7950, though its Boost Edition and famous GeForce GTX 660 Ti still perform considerably better.
Still, Radeon R9 270X has a launching price of just $199 which makes it a very competitive card.
Expect to run most modern demanding games, such as Crysis 3 and Metro Last Light at highest settings while using a 1080p resolution.
|GeForce GTX 660 Ti Inno3D Edition is a special edition of GeForce GTX 660 Ti. |
It's a rename with no new features - not even a custom cooling system and so the so the performance is exactly like the standard GeForce GTX 660 Ti.
