Texel Rate

The GeForce RTX 4090 should be quite a bit (about 599%) better at AF than the GeForce RTX 2060. (explain)

GeForce RTX 4090		1144320 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 980520 (599%)

Pixel Rate

The GeForce RTX 4090 will be a lot (approximately 500%) better at FSAA than the GeForce RTX 2060, and should be able to handle higher screen resolutions better. (explain)

GeForce RTX 4090		393360 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 327840 (500%)

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 transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
