Radeon RX 5600		150 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 26 Watts (17%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 is 3% quicker than the Radeon RX 6650 XT overall, because of its higher data rate. (explain)

Radeon RX 5600		294912 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 7840 (3%)

Texel Rate

The Radeon RX 6650 XT should be a lot (approximately 49%) more effective at anisotropic filtering than the Radeon RX 5600. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 87040 (49%)

Pixel Rate

The Radeon RX 6650 XT should be much (about 49%) more effective at FSAA than the Radeon RX 5600, and also should be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon RX 5600		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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
