Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 295 Watts (536%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti should be 1068% quicker than the GeForce GTX 750 in general, due to its greater data rate. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 854297 (1068%)

Texel Rate

The GeForce RTX 3080 Ti will be much (more or less 1238%) faster with regards to anisotropic filtering than the GeForce GTX 750. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 404160 (1238%)

Pixel Rate

The GeForce RTX 3080 Ti is quite a bit (more or less 837%) faster with regards to FSAA than the GeForce GTX 750, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 136560 (837%)

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 information (counted in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
