Radeon RX 6650 XT		287072 MB/sec
	Difference: 56992 (20%)

Texel Rate

The Radeon RX 6650 XT should be quite a bit (about 33%) more effective at anisotropic filtering than the Radeon RX 5600 XT. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 65040 (33%)

Pixel Rate

The Radeon RX 6650 XT should be a lot (more or less 49%) more effective at FSAA than the Radeon RX 5600 XT, and also capable of handling higher resolutions more effectively. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 43520 (49%)

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 (measured in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of 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 output rate is also dependant on lots of 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.
