GeForce RTX 2060 vs GeForce RTX 3080 12 GB

Intro

Compare all that to the GeForce RTX 3080 12 GB, which comes with GPU core speed of 1260 MHz, and 12288 MB of GDDR6X memory running at 1188 MHz through a 384-bit bus. It also is comprised of 8960 SPUs, 280 Texture Address Units, and 112 Raster Operation Units.

	Difference: 590234 (172%)

Texel Rate

The GeForce RTX 3080 12 GB will be quite a bit (approximately 115%) more effective at anisotropic filtering than the GeForce RTX 2060. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 189000 (115%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3080 12 GB is the winner, and very much so. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 75600 (115%)

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 (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
