GeForce RTX 2070		458752 MB/sec
	Difference: 275251 (60%)

Texel Rate

The GeForce RTX 4080 is a lot (more or less 230%) faster with regards to anisotropic filtering than the GeForce RTX 2070. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 467280 (230%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 4080 is superior to the GeForce RTX 2070, by a large margin. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 156720 (174%)

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 largest amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 can be applied per second. This figure 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
