GeForce GTX 780 Ti vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which comes with GPU clock speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also features 2304 Stream Processors, 144 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

In theory, the Radeon RX 5600 XT should perform a bit faster than the GeForce GTX 780 Ti overall. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce GTX 780 Ti		336000 MB/sec
	Difference: 8064 (2%)

Texel Rate

The GeForce GTX 780 Ti will be a little bit (more or less 6%) more effective at anisotropic filtering than the Radeon RX 5600 XT. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 12000 (6%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5600 XT is the winner, and very much so. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 46000 (110%)

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 megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
