Texel Rate

The Radeon RX 6750 XT is a lot (about 139%) faster with regards to anisotropic filtering than the GeForce GTX 980. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 199872 (139%)

Pixel Rate

The Radeon RX 6750 XT will be much (about 91%) better at FSAA than the GeForce GTX 980, and also will be capable of handling higher screen resolutions better. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
GeForce GTX 980		72064 Mpixels/sec
	Difference: 65536 (91%)

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 (counted in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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