In theory, the Radeon RX 6950 XT should be 100% faster than the GeForce GTX 1660 Ti in general, due to its greater bandwidth. (explain)

Radeon RX 6950 XT		589824 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 294912 (100%)

Texel Rate

The Radeon RX 6950 XT is a lot (about 328%) more effective at texture filtering than the GeForce GTX 1660 Ti. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 472000 (328%)

Pixel Rate

The Radeon RX 6950 XT will be a lot (more or less 242%) more effective at FSAA than the GeForce GTX 1660 Ti, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 174400 (242%)

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 (in units of MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the 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 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
