Radeon RX 5700 XT vs Radeon RX 6800 XT

Intro

The Radeon RX 5700 XT comes with a GPU core speed of 1605 MHz, and the 8096 MB of GDDR6 RAM is set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2560 Stream Processors, 160 TAUs, and 64 ROPs.

Compare those specs to the Radeon RX 6800 XT, which has a core clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also features a 256-bit bus, and uses a 7 nm design. It is made up of 4608 SPUs, 288 TAUs, and 128 Raster Operation Units.

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

Texel Rate

The Radeon RX 6800 XT should be a lot (about 105%) faster with regards to AF 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

The Radeon RX 6800 XT will be much (more or less 127%) faster with regards to anti-aliasing than the Radeon RX 5700 XT, and also will be able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
