Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 15 Watts (6%)

Memory Bandwidth

As far as performance goes, the Radeon RX 5700 XT 50th Anniversary Edition should theoretically be a lot better than the GeForce GTX 980 Ti in general. (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 should be quite a bit (more or less 53%) more effective at texture 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 using a high screen resolution is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is the winner, not by a very large margin though. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses 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 amount of texture map elements (texels) that can be applied in one second. This figure 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
