GeForce RTX 2060 vs GeForce RTX 3080 Ti

Intro

Compare all that to the GeForce RTX 3080 Ti, which comes with GPU core speed of 1365 MHz, and 12288 MB of GDDR6X memory running at 1188 MHz through a 384-bit bus. It also is comprised of 10240 SPUs, 320 Texture Address Units, and 112 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 190 Watts (119%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti will be 172% quicker than the GeForce RTX 2060 overall, due to its greater bandwidth. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce RTX 2060		344064 MB/sec
	Difference: 590233 (172%)

Texel Rate

The GeForce RTX 3080 Ti should be much (approximately 167%) faster with regards to texture filtering than the GeForce RTX 2060. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 273000 (167%)

Pixel Rate

The GeForce RTX 3080 Ti is quite a bit (more or less 133%) faster with regards to FSAA than the GeForce RTX 2060, and capable of handling higher resolutions while still performing well. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 87360 (133%)

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 past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
