GeForce RTX 3080 vs Radeon RX 5600

Intro

Compare those specs to the Radeon RX 5600, which comes with a core clock frequency of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also uses a 192-bit memory bus, and uses a 7 nm design. It features 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Radeon RX 5600		176000 Mtexels/sec
	Difference: 215680 (123%)

Pixel Rate

The GeForce RTX 3080 is quite a bit (about 57%) better at AA than the Radeon RX 5600, and will be able to handle higher screen resolutions better. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 50240 (57%)

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 (measured in MB per second) that can be transported 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, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
