GeForce GTX 750 vs GeForce RTX 4080

Intro

Compare those specifications to the GeForce RTX 4080, which uses a 4 nm design. nVidia has clocked the core speed at 2205 MHz. The GDDR6X RAM runs at a speed of 1400 MHz on this model. It features 9728 SPUs along with 304 TAUs and 112 Rasterization Operator Units.

GeForce GTX 750		55 Watts
GeForce RTX 4080		320 Watts
	Difference: 265 Watts (482%)

Memory Bandwidth

In theory, the GeForce RTX 4080 will be 818% faster than the GeForce GTX 750 overall, due to its greater bandwidth. (explain)

GeForce RTX 4080		734003 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 654003 (818%)

Texel Rate

The GeForce RTX 4080 should be much (approximately 1954%) more effective at texture filtering than the GeForce GTX 750. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 637680 (1954%)

Pixel Rate

The GeForce RTX 4080 will be a lot (about 1413%) better at AA than the GeForce GTX 750, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce GTX 750		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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
