GeForce GTX 980		165 Watts
GeForce RTX 4080		320 Watts
	Difference: 155 Watts (94%)

Memory Bandwidth

The GeForce RTX 4080 should in theory be quite a bit faster than the GeForce GTX 980 in general. (explain)

GeForce RTX 4080		734003 MB/sec
GeForce GTX 980		224000 MB/sec
	Difference: 510003 (228%)

Texel Rate

The GeForce RTX 4080 will be a lot (about 365%) better at AF than the GeForce GTX 980. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 526192 (365%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 4080 is superior to the GeForce GTX 980, and very much so. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce GTX 980		72064 Mpixels/sec
	Difference: 174896 (243%)

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 data (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
