GeForce RTX 2080 vs Radeon RX 5700 XT

Intro

The GeForce RTX 2080 comes with a clock speed of 1515 MHz and a GDDR6 memory speed of 14 MHz. It also features a 256-bit memory bus, and uses a 12 nm design. It features 2944 SPUs, 184 Texture Address Units, and 64 Raster Operation Units.

Compare that to the Radeon RX 5700 XT, which has a clock speed of 1605 MHz and a GDDR6 memory frequency of 14000 MHz. It also makes use of a 256-bit memory bus, and uses 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 in theory they should have the same performance. (explain)

Texel Rate

The GeForce RTX 2080 should be a small bit (about 9%) faster with regards to anisotropic filtering 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 small bit (approximately 6%) faster with regards to FSAA than the GeForce RTX 2080, and also should be able to handle higher resolutions without slowing down too much. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher 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 the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
