GeForce GTX 660 Ti vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which comes with a GPU core clock speed of 825 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Radeon R7 M260X		19800 Mtexels/sec
	Difference: 82680 (418%)

Pixel Rate

The GeForce GTX 660 Ti will be much (more or less 233%) better at anti-aliasing than the Radeon R7 M260X, and also able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 15360 (233%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
