Geforce GTX 780 vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which has a clock frequency of 1375 MHz and a GDDR6 memory speed of 14000 MHz. It also makes use of a 192-bit bus, and makes use of a 7 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 64 ROPs.

Geforce GTX 780		165696 Mtexels/sec
	Difference: 32304 (19%)

Pixel Rate

The Radeon RX 5600 XT is quite a bit (about 112%) better at FSAA than the Geforce GTX 780, and should be capable of handling higher screen resolutions better. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 46576 (112%)

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 information (measured in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
