GeForce GTX 780 Ti vs GeForce RTX 2060

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2060 should perform just a bit faster than the GeForce GTX 780 Ti in general. (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 a lot (about 28%) better at AF 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 superior to the GeForce GTX 780 Ti, and very much so. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the ability to get to the max fill rate.
