Texel Rate

The GeForce RTX 4080 is much (more or less 112%) more effective at anisotropic filtering than the GeForce RTX 2080 SUPER. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 353520 (112%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 4080 is superior to the GeForce RTX 2080 SUPER, by a large margin. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 141360 (134%)

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 information (counted in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
