Radeon RX 460 2GB		112000 MB/sec
	Difference: 16000 (14%)

Texel Rate

The Radeon RX 460 2GB will be a lot (about 64%) better at texture filtering than the Radeon HD 6850. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon HD 6850		37200 Mtexels/sec
	Difference: 23840 (64%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 6850 is superior to the Radeon RX 460 2GB, and very much so. (explain)

Radeon HD 6850		24800 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 7360 (42%)

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 largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core 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 amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
