GeForce RTX 2080 SUPER vs GeForce RTX 3080

Intro

Compare that to the GeForce RTX 3080, which has a clock speed of 1440 MHz and a GDDR6X memory speed of 1188 MHz. It also uses a 320-bit memory bus, and makes use of a 8 nm design. It is made up of 8704 SPUs, 272 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 is 53% faster than the GeForce RTX 2080 SUPER in general, due to its greater bandwidth. (explain)

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

Texel Rate

The GeForce RTX 3080 is much (more or less 24%) more effective 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

The GeForce RTX 3080 will be quite a bit (more or less 31%) better at full screen anti-aliasing than the GeForce RTX 2080 SUPER, and also should be capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
