Geforce GTX 770		224384 MB/sec
	Difference: 37760 (17%)

Texel Rate

The Radeon RX 6600 XT should be a lot (more or less 88%) better at anisotropic filtering than the Geforce GTX 770. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 118016 (88%)

Pixel Rate

The Radeon RX 6600 XT is quite a bit (approximately 276%) faster with regards to FSAA than the Geforce GTX 770, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 92480 (276%)

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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated 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 it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
