Radeon RX 5700 vs Radeon RX 6800 XT

Intro

Compare that to the Radeon RX 6800 XT, which features a clock speed of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and uses a 7 nm design. It features 4608 SPUs, 288 Texture Address Units, and 128 ROPs.

Radeon RX 5700		180 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 120 Watts (67%)

Memory Bandwidth

In theory, the Radeon RX 6800 XT should perform just a bit faster than the Radeon RX 5700 overall. (explain)

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

Texel Rate

The Radeon RX 6800 XT is quite a bit (about 149%) better at AF 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 the winner, by a large margin. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
