GeForce GTX 1080 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which makes use of a 7 nm design. AMD has clocked the core speed at 1375 MHz. The GDDR6 RAM is set to run at a frequency of 1500 MHz on this particular card. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
GeForce GTX 1080		180 Watts
	Difference: 30 Watts (20%)

Memory Bandwidth

Performance-wise, the GeForce GTX 1080 should theoretically be a small bit better than the Radeon RX 5600 in general. (explain)

GeForce GTX 1080		327680 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 32768 (11%)

Texel Rate

The GeForce GTX 1080 is quite a bit (more or less 46%) faster with regards to anisotropic filtering than the Radeon RX 5600. (explain)

GeForce GTX 1080		257120 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 81120 (46%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1080 is a better choice, not by a very large margin though. (explain)

GeForce GTX 1080		102848 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 14848 (17%)

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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
