GeForce GTX 980		224000 MB/sec
	Difference: 5376 (2%)

Texel Rate

The Radeon RX 5500 will be a small bit (more or less 2%) better at anisotropic filtering than the GeForce GTX 980. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 2832 (2%)

Pixel Rate

The GeForce GTX 980 should be quite a bit (more or less 35%) better at full screen anti-aliasing than the Radeon RX 5500, and will be capable of handling higher resolutions better. (explain)

GeForce GTX 980		72064 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 18624 (35%)

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 (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
