GeForce RTX 2080 Ti vs GeForce RTX 3080

Intro

Compare all of that to the GeForce RTX 3080, which uses a 8 nm design. nVidia has clocked the core speed at 1440 MHz. The GDDR6X RAM is set to run at a speed of 1188 MHz on this particular model. It features 8704 SPUs along with 272 TAUs and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce RTX 3080 should in theory be much faster than the GeForce RTX 2080 Ti in general. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce RTX 2080 Ti		630784 MB/sec
	Difference: 147763 (23%)

Texel Rate

The GeForce RTX 3080 is a little bit (more or less 7%) faster with regards to texture filtering than the GeForce RTX 2080 Ti. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 2080 Ti		367200 Mtexels/sec
	Difference: 24480 (7%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3080 is the winner, but not by far. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 19440 (16%)

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 maximum amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
