GeForce GTX 1080 vs GeForce RTX 2060

Intro

Compare those specs to the GeForce RTX 2060, which comes with a core clock frequency of 1365 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 192-bit bus, and uses a 12 nm design. It is made up of 1920 SPUs, 120 TAUs, 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

In theory, the GeForce RTX 2060 should perform just a 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 should be quite a bit (approximately 57%) more effective 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 a high screen resolution is important to you, then the GeForce GTX 1080 is a better choice, by far. (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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, 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 amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
