In theory, the Radeon RX 5700 XT 50th Anniversary Edition is 37% quicker than the GeForce GTX 980 Ti overall, due to its higher data rate. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
GeForce GTX 980 Ti		336000 MB/sec
	Difference: 122752 (37%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition will be quite a bit (more or less 53%) better at anisotropic filtering than the GeForce GTX 980 Ti. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 92800 (53%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is superior to the GeForce GTX 980 Ti, but not by far. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
GeForce GTX 980 Ti		96000 Mpixels/sec
	Difference: 11520 (12%)

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 data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
