Texel Rate

The GeForce RTX 3080 12 GB is a lot (about 581%) better at texture filtering than the GeForce GTX 285 1GB. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
GeForce GTX 285 1GB		51840 Mtexels/sec
	Difference: 300960 (581%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3080 12 GB is a better choice, by far. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
GeForce GTX 285 1GB		20736 Mpixels/sec
	Difference: 120384 (581%)

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 max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
