GeForce RTX 2080 vs Radeon RX 5700 XT 50th Anniversary Edition

Intro

Compare all of that to the Radeon RX 5700 XT 50th Anniversary Edition, which uses a 7 nm design. AMD has set the core frequency at 1680 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this model. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080		215 Watts
Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 20 Watts (9%)

Memory Bandwidth

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

Texel Rate

The GeForce RTX 2080 should be just a bit (approximately 4%) more effective at anisotropic filtering than the Radeon RX 5700 XT 50th Anniversary Edition. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
	Difference: 9960 (4%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is a better choice, not by a very large margin though. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 10560 (11%)

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 (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
