GeForce GTX 780 Ti vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which features a clock speed of 1375 MHz and a GDDR6 memory frequency of 1500 MHz. It also uses a 192-bit memory bus, and uses a 7 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 5600		150 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the GeForce GTX 780 Ti is 14% faster than the Radeon RX 5600 in general, due to its greater bandwidth. (explain)

GeForce GTX 780 Ti		336000 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 41088 (14%)

Texel Rate

The GeForce GTX 780 Ti will be a small bit (more or less 19%) faster with regards to texture filtering than the Radeon RX 5600. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 34000 (19%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5600 is a better choice, and very much so. (explain)

Radeon RX 5600		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 max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
