GeForce GTX 980		224000 MB/sec
	Difference: 218368 (97%)

Texel Rate

The Radeon RX 6750 XT should be much (more or less 139%) more effective at 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 is much (about 91%) faster with regards to anti-aliasing than the GeForce GTX 980, and will be able to handle higher screen resolutions while still performing well. (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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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