GeForce GTX 750 vs GeForce RTX 3080 Ti

Intro

Compare all that to the GeForce RTX 3080 Ti, which features GPU core speed of 1365 MHz, and 12288 MB of GDDR6X RAM running at 1188 MHz through a 384-bit bus. It also is made up of 10240 Stream Processors, 320 Texture Address Units, and 112 ROPs.

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

Theoretically speaking, the GeForce RTX 3080 Ti will be 1068% quicker than the GeForce GTX 750 overall, due to its higher 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%) more effective at texture 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 (approximately 837%) more effective at FSAA than the GeForce GTX 750, and should be capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
