Texel Rate

The GeForce RTX 4080 should be a lot (approximately 1543%) more effective at AF than the GeForce GTX 750 Ti. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 629520 (1543%)

Pixel Rate

The GeForce RTX 4080 will be a lot (more or less 1413%) more effective at anti-aliasing than the GeForce GTX 750 Ti, and also able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 230640 (1413%)

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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
