GeForce GTX 980 Ti vs Radeon RX 5600

Intro

Compare those specifications to the Radeon RX 5600, which has a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

The GeForce GTX 980 Ti, in theory, should be a little bit faster than the Radeon RX 5600 in general. (explain)

GeForce GTX 980 Ti		336000 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 41088 (14%)

Texel Rate

Both cards have exactly the same texel rate, so theoretically they should perform equally good at at anisotropic filtering. (explain)

Pixel Rate

The GeForce GTX 980 Ti is a bit (more or less 9%) more effective at FSAA than the Radeon RX 5600, and also capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 8000 (9%)

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 largest amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
