GeForce GTX 780 Ti vs GeForce RTX 2060

Intro

Compare those specifications to the GeForce RTX 2060, which features a clock frequency of 1365 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 192-bit bus, and uses a 12 nm design. It is comprised of 1920 SPUs, 120 TAUs, and 48 ROPs.

GeForce RTX 2060		160 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

The GeForce RTX 2060, in theory, should be just a bit faster than the GeForce GTX 780 Ti overall. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce GTX 780 Ti		336000 MB/sec
	Difference: 8064 (2%)

Texel Rate

The GeForce GTX 780 Ti should be much (more or less 28%) faster with regards to texture filtering than the GeForce RTX 2060. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 46200 (28%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 2060 is the winner, by a large margin. (explain)

GeForce RTX 2060		65520 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 23520 (56%)

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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
