Radeon RX 5700 XT vs Radeon RX 6800 XT

Intro

The Radeon RX 5700 XT uses a 7 nm design. AMD has clocked the core frequency at 1605 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this model. It features 2560 SPUs as well as 160 TAUs and 64 Rasterization Operator Units.

Compare those specifications to the Radeon RX 6800 XT, which comes with core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 4608 SPUs along with 288 TAUs and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT 225 Watts
Radeon RX 6800 XT 300 Watts
Difference: 75 Watts (33%)

Memory Bandwidth

The Radeon RX 6800 XT, in theory, should be just a bit faster than the Radeon RX 5700 XT overall. (explain)

Radeon RX 6800 XT 524288 MB/sec
Radeon RX 5700 XT 458752 MB/sec
Difference: 65536 (14%)

Texel Rate

The Radeon RX 6800 XT will be a lot (more or less 105%) more effective at anisotropic filtering than the Radeon RX 5700 XT. (explain)

Radeon RX 6800 XT 525600 Mtexels/sec
Radeon RX 5700 XT 256800 Mtexels/sec
Difference: 268800 (105%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6800 XT is a better choice, by a large margin. (explain)

Radeon RX 6800 XT 233600 Mpixels/sec
Radeon RX 5700 XT 102720 Mpixels/sec
Difference: 130880 (127%)

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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
