Radeon RX 5700 vs Radeon RX 6800 XT

Intro

The Radeon RX 5700 uses a 7 nm design. AMD has clocked the core speed at 1465 MHz. The GDDR6 memory runs at a speed of 1750 MHz on this particular model. It features 2304 SPUs as well as 144 TAUs and 64 Rasterization Operator Units.

Compare that to the Radeon RX 6800 XT, which makes use of a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this particular card. It features 4608 SPUs as well as 288 Texture Address Units and 128 ROPs.

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

Texel Rate

The Radeon RX 6800 XT is much (approximately 149%) better at anisotropic 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 high levels of AA is important to you, then the Radeon RX 6800 XT is the winner, by far. (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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
