GeForce RTX 2080 vs Radeon RX 5700 XT

Intro

Compare all that to the Radeon RX 5700 XT, which comes with a clock frequency of 1605 MHz and a GDDR6 memory frequency of 1750 MHz. It also features a 256-bit memory bus, and makes use of a 7 nm design. It features 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080		215 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 10 Watts (5%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce RTX 2080 is a little bit (about 9%) faster with regards to AF than the Radeon RX 5700 XT. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 21960 (9%)

Pixel Rate

The Radeon RX 5700 XT is a bit (approximately 6%) faster with regards to FSAA than the GeForce RTX 2080, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 5760 (6%)

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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
