VS

Radeon RX 5700 XT vs Radeon RX 6800 XT

Intro

The Radeon RX 5700 XT features a GPU clock speed of 1605 MHz, and the 8096 MB of GDDR6 memory runs at 1750 MHz through a 256-bit bus. It also features 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 6800 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1825 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this model. It features 4608 SPUs as well as 288 TAUs and 128 ROPs.

The Radeon RX 6800 XT is quite a bit (approximately 105%) faster with regards to texture 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 running with lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is superior to the Radeon RX 5700 XT, by far. (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 (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
