GeForce GTX 1080 vs GeForce RTX 2060

Intro

The GeForce GTX 1080 makes use of a 16 nm design. nVidia has clocked the core frequency at 1607 MHz. The GDDR5X memory is set to run at a frequency of 1251 MHz on this specific model. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

Compare all that to the GeForce RTX 2060, which comes with core speeds of 1365 MHz on the GPU, and 14000 MHz on the 6144 MB of GDDR6 memory. It features 1920 SPUs along with 120 TAUs and 48 Rasterization Operator 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 is 5% faster than the GeForce GTX 1080 in general, because of its higher bandwidth. (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 (more or less 57%) faster with regards to anisotropic filtering than the GeForce RTX 2060. (explain)

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

Pixel Rate

The GeForce GTX 1080 will be quite a bit (about 57%) more effective at AA than the GeForce RTX 2060, and should be capable of handling higher resolutions better. (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.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
