GeForce GTX 780 Ti vs GeForce RTX 2060

Intro

Compare those specifications to the GeForce RTX 2060, which uses a 12 nm design. nVidia has set the core speed at 1365 MHz. The GDDR6 memory works at a speed of 1750 MHz on this card. It features 1920 SPUs along with 120 TAUs and 48 Rasterization Operator Units.

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

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2060 should be 2% quicker than the GeForce GTX 780 Ti in general, due to its greater bandwidth. (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 (approximately 28%) more effective 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

The GeForce RTX 2060 is much (approximately 56%) faster with regards to AA than the GeForce GTX 780 Ti, and also should be capable of handling higher screen resolutions better. (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 largest amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
