Radeon RX 5600 XT		160 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 16 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT should be 20% quicker than the Radeon RX 6650 XT in general, due to its higher bandwidth. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 56992 (20%)

Texel Rate

The Radeon RX 6650 XT will be quite a bit (approximately 33%) more effective at AF 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

If using a high screen resolution is important to you, then the Radeon RX 6650 XT is the winner, by far. (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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
