	Difference: 344064 (300%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be a lot (approximately 664%) faster with regards to anisotropic filtering than the Radeon RX 550. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 233600 (664%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is superior to the Radeon RX 550, by far. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 89920 (511%)

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 transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher 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 one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
