The Radeon RX 470 4GB is quite a bit (approximately 94%) better at AF than the Radeon RX 460. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
Radeon RX 460		61040 Mtexels/sec
	Difference: 57488 (94%)

Pixel Rate

The Radeon RX 470 4GB is much (approximately 70%) better at full screen anti-aliasing than the Radeon RX 460, and also should be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 12192 (70%)

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one 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 - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
