GeForce GTX 1080 vs GeForce RTX 2060

Intro

Compare that to the GeForce RTX 2060, which comes with GPU core speed of 1365 MHz, and 6144 MB of GDDR6 RAM set to run at 1750 MHz through a 192-bit bus. It also is made up of 1920 Stream Processors, 120 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
GeForce GTX 1080		180 Watts
	Difference: 20 Watts (13%)

Memory Bandwidth

The GeForce RTX 2060, in theory, should be a small bit faster than the GeForce GTX 1080 overall. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce GTX 1080		327680 MB/sec
	Difference: 16384 (5%)

Texel Rate

The GeForce GTX 1080 is quite a bit (approximately 57%) better at AF than the GeForce RTX 2060. (explain)

GeForce GTX 1080		257120 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 93320 (57%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1080 is the winner, and very much so. (explain)

GeForce GTX 1080		102848 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 37328 (57%)

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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
