Radeon RX 6600		132 Watts
Radeon HD 7950		200 Watts
	Difference: 68 Watts (52%)

Memory Bandwidth

In theory, the Radeon HD 7950 will be 5% quicker than the Radeon RX 6600 in general, due to its higher bandwidth. (explain)

Radeon HD 7950		240000 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 10624 (5%)

Texel Rate

The Radeon RX 6600 should be quite a bit (about 103%) faster with regards to texture filtering than the Radeon HD 7950. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon HD 7950		89600 Mtexels/sec
	Difference: 92512 (103%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6600 is the winner, by far. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon HD 7950		25600 Mpixels/sec
	Difference: 78464 (307%)

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 transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be applied per second. This number is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
