Radeon HD 5750 512MB		73600 MB/sec
	Difference: 137600 (187%)

Texel Rate

The Radeon RX 470 should be quite a bit (more or less 370%) better at texture filtering than the Radeon HD 5750 512MB. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 93328 (370%)

Pixel Rate

The Radeon RX 470 is quite a bit (approximately 165%) more effective at anti-aliasing than the Radeon HD 5750 512MB, and also able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 18432 (165%)

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 information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
