GeForce GTX 460 (OEM) vs Radeon R7 260X

Intro

Compare all of that to the Radeon R7 260X, which comes with clock speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 RAM. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Texel Rate

The Radeon R7 260X is a lot (approximately 69%) better at texture filtering than the GeForce GTX 460 (OEM). (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 25200 (69%)

Pixel Rate

The GeForce GTX 460 (OEM) is a little bit (more or less 18%) more effective at AA than the Radeon R7 260X, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 3200 (18%)

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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
