Texel Rate

The Radeon RX 6600 XT is a lot (more or less 43%) better at anisotropic filtering than the Radeon RX 5600. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 75904 (43%)

Pixel Rate

The Radeon RX 6600 XT is much (about 43%) better at FSAA than the Radeon RX 5600, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 37952 (43%)

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 data (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
