GeForce GTX 660 Ti		150 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 185 Watts (123%)

Memory Bandwidth

In theory, the Radeon RX 6950 XT will be 310% quicker than the GeForce GTX 660 Ti in general, due to its higher data rate. (explain)

Radeon RX 6950 XT		589824 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 445824 (310%)

Texel Rate

The Radeon RX 6950 XT will be quite a bit (more or less 501%) more effective at texture filtering than the GeForce GTX 660 Ti. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 513520 (501%)

Pixel Rate

The Radeon RX 6950 XT will be much (more or less 1022%) faster with regards to FSAA than the GeForce GTX 660 Ti, and capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 224440 (1022%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface 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 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
