Radeon RX 6600		229376 MB/sec
	Difference: 549171 (239%)

Texel Rate

The GeForce RTX 3080 should be much (more or less 115%) faster with regards to anisotropic filtering than the Radeon RX 6600. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 209568 (115%)

Pixel Rate

The GeForce RTX 3080 should be quite a bit (approximately 33%) more effective at FSAA than the Radeon RX 6600, and capable of handling higher resolutions better. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 6600		104064 Mpixels/sec
	Difference: 34176 (33%)

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 data (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
