	Difference: 247552 (117%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition is much (more or less 127%) more effective at texture filtering than the Radeon RX 470 4GB. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 150272 (127%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is a better choice, by far. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 77888 (263%)

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 maximum amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 in one second. This is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
