GeForce RTX 2080 SUPER vs GeForce RTX 4080

Intro

Compare those specifications to the GeForce RTX 4080, which features a core clock frequency of 2205 MHz and a GDDR6X memory frequency of 1400 MHz. It also features a 256-bit bus, and makes use of a 4 nm design. It features 9728 SPUs, 304 Texture Address Units, and 112 ROPs.

GeForce RTX 2080 SUPER		507904 MB/sec
	Difference: 226099 (45%)

Texel Rate

The GeForce RTX 4080 is quite a bit (about 112%) better at anisotropic filtering than the GeForce RTX 2080 SUPER. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 353520 (112%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 4080 is a better choice, by a large margin. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 141360 (134%)

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 data (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
