GeForce GTX 980 165 Watts
Difference: 15 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 480 should be 17% quicker than the GeForce GTX 980 in general, due to its greater data rate. (explain)

Radeon RX 480 262144 MB/sec
GeForce GTX 980 224000 MB/sec
Difference: 38144 (17%)

Texel Rate

The Radeon RX 480 should be just a bit (approximately 12%) better at anisotropic filtering than the GeForce GTX 980. (explain)

Radeon RX 480 161280 Mtexels/sec
GeForce GTX 980 144128 Mtexels/sec
Difference: 17152 (12%)

Pixel Rate

The GeForce GTX 980 is much (more or less 101%) better at AA than the Radeon RX 480, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 980 72064 Mpixels/sec
Radeon RX 480 35840 Mpixels/sec
Difference: 36224 (101%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
