GeForce GTX 780 Ti vs GeForce RTX 2060

Intro

Compare that to the GeForce RTX 2060, which features a GPU core clock speed of 1365 MHz, and 6144 MB of GDDR6 memory set to run at 1750 MHz through a 192-bit bus. It also is comprised of 1920 SPUs, 120 TAUs, and 48 ROPs.

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

Texel Rate

The GeForce GTX 780 Ti should be a lot (about 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 using lots of anti-aliasing is important to you, then the GeForce RTX 2060 is superior to the GeForce GTX 780 Ti, 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: 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. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
