Texel Rate

The Radeon RX 460 2GB is a lot (about 66%) more effective at AF than the GeForce GTX 260. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 24176 (66%)

Pixel Rate

The Radeon RX 460 2GB will be a bit (about 8%) better at AA than the GeForce GTX 260, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 1312 (8%)

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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
