GeForce GTX 780 Ti vs GeForce RTX 2060

Intro

Compare all that to the GeForce RTX 2060, which has core clock speeds of 1365 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR6 memory. It features 1920 SPUs along with 120 TAUs and 48 Rasterization Operator Units.

GeForce RTX 2060		163800 Mtexels/sec
	Difference: 46200 (28%)

Pixel Rate

The GeForce RTX 2060 should be much (about 56%) more effective at full screen anti-aliasing than the GeForce GTX 780 Ti, and should be able to handle higher screen resolutions without slowing down too much. (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 max amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
