Radeon RX 460 2GB		112000 MB/sec
	Difference: 412288 (368%)

Texel Rate

The Radeon RX 6800 XT is quite a bit (approximately 761%) faster with regards to texture filtering than the Radeon RX 460 2GB. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 464560 (761%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6800 XT is the winner, by a large margin. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 216160 (1239%)

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 (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out 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 faster 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total 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 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 video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
