GeForce RTX 2080 SUPER vs GeForce RTX 3080

Intro

The GeForce RTX 2080 SUPER has a clock speed of 1650 MHz and a GDDR6 memory speed of 1937 MHz. It also features a 256-bit bus, and uses a 12 nm design. It is made up of 3072 SPUs, 192 TAUs, and 64 ROPs.

Compare those specifications to the GeForce RTX 3080, which features GPU core speed of 1440 MHz, and 10240 MB of GDDR6X RAM set to run at 1188 MHz through a 320-bit bus. It also is comprised of 8704 Stream Processors, 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, the GeForce RTX 3080 should perform a lot faster 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 quite a bit (more or less 24%) more effective at texture 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 using a high screen resolution is important to you, then the GeForce RTX 3080 is a better choice, 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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past 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 RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
