GeForce RTX 2060 vs GeForce RTX 2080

Intro

Compare those specs to the GeForce RTX 2080, which uses a 12 nm design. nVidia has set the core speed at 1515 MHz. The GDDR6 RAM is set to run at a frequency of 1750 MHz on this specific model. It features 2944 SPUs as well as 184 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
GeForce RTX 2080		215 Watts
	Difference: 55 Watts (34%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 is 33% faster than the GeForce RTX 2060 in general, because of its greater data rate. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce RTX 2060		344064 MB/sec
	Difference: 114688 (33%)

Texel Rate

The GeForce RTX 2080 will be a lot (about 70%) more effective at anisotropic filtering than the GeForce RTX 2060. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 114960 (70%)

Pixel Rate

The GeForce RTX 2080 should be a lot (about 48%) better at full screen anti-aliasing than the GeForce RTX 2060, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 31440 (48%)

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 megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
