GeForce RTX 2080 SUPER vs GeForce RTX 3080

Intro

Compare all that to the GeForce RTX 3080, which makes use of a 8 nm design. nVidia has clocked the core speed at 1440 MHz. The GDDR6X memory runs at a speed of 1188 MHz on this particular model. It features 8704 SPUs as well as 272 TAUs and 96 ROPs.

GeForce RTX 2080 SUPER		250 Watts
GeForce RTX 3080		320 Watts
	Difference: 70 Watts (28%)

Memory Bandwidth

Performance-wise, the GeForce RTX 3080 should in theory be quite a bit better than the GeForce RTX 2080 SUPER overall. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce RTX 2080 SUPER		507904 MB/sec
	Difference: 270643 (53%)

Texel Rate

The GeForce RTX 3080 should be a lot (approximately 24%) better at anisotropic filtering than the GeForce RTX 2080 SUPER. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 74880 (24%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 3080 is the winner, and very much so. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 32640 (31%)

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 max amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
