Radeon RX 5700 vs Radeon RX 6800 XT

Intro

The Radeon RX 5700 has a GPU core clock speed of 1465 MHz, and the 8096 MB of GDDR6 RAM is set to run at 1750 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 TAUs, and 64 Raster Operation Units.

Compare all of that to the Radeon RX 6800 XT, which comes with GPU core speed of 1825 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also features 4608 SPUs, 288 Texture Address Units, and 128 ROPs.

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

Texel Rate

The Radeon RX 6800 XT should be much (more or less 149%) faster with regards to texture filtering than the Radeon RX 5700. (explain)

Radeon RX 6800 XT 525600 Mtexels/sec
Radeon RX 5700 210960 Mtexels/sec
Difference: 314640 (149%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is superior to the Radeon RX 5700, and very much so. (explain)

Radeon RX 6800 XT 233600 Mpixels/sec
Radeon RX 5700 93760 Mpixels/sec
Difference: 139840 (149%)

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 max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
