GeForce GTX 780 Ti vs GeForce RTX 2060

Intro

Compare all of that to the GeForce RTX 2060, which features a GPU core clock 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 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

In theory, the GeForce RTX 2060 should be 2% faster than the GeForce GTX 780 Ti overall, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 780 Ti is much (about 28%) faster with regards to anisotropic 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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher 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 number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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.
