GeForce GTX 750		55 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 105 Watts (191%)

Memory Bandwidth

In theory, the Radeon RX 6600 XT should be 228% faster than the GeForce GTX 750 overall, due to its higher data rate. (explain)

Radeon RX 6600 XT		262144 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 182144 (228%)

Texel Rate

The Radeon RX 6600 XT is a lot (more or less 672%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 219264 (672%)

Pixel Rate

The Radeon RX 6600 XT will be much (approximately 672%) better at FSAA than the GeForce GTX 750, and also able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 109632 (672%)

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 maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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