GeForce GTX 980 Ti vs Radeon RX 5600

Intro

Compare those specs to the Radeon RX 5600, which uses a 7 nm design. AMD has clocked the core speed at 1375 MHz. The GDDR6 RAM works at a speed of 1500 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator 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

Theoretically, the GeForce GTX 980 Ti should perform a bit faster than the Radeon RX 5600 overall. (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 fill rate, so theoretically they should perform equally good at at anisotropic filtering. (explain)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 980 Ti is a better choice, not by a very large margin though. (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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, 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 write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
