Texel Rate

The Radeon RX 460 2GB should be quite a bit (about 45%) faster with regards to AF than the GeForce GTX 480. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 19040 (45%)

Pixel Rate

The GeForce GTX 480 is much (more or less 93%) more effective at full screen anti-aliasing than the Radeon RX 460 2GB, and able to handle higher resolutions better. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 16160 (93%)

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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
