GeForce GTX 980 Ti vs Radeon RX 5600

Intro

Compare that to the Radeon RX 5600, which features a clock speed of 1375 MHz and a GDDR6 memory frequency of 1500 MHz. It also makes use of a 192-bit memory bus, and uses a 7 nm design. It is comprised of 2048 SPUs, 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 the exact same texel fill rate, so in theory they should perform equally good at at anisotropic filtering. (explain)

Pixel Rate

The GeForce GTX 980 Ti will be a small bit (about 9%) better at FSAA than the Radeon RX 5600, and also able to handle 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 (in units of MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better 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 video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
