Radeon RX 5700 XT vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which features GPU core speed of 1700 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 3840 Stream Processors, 240 Texture Address Units, and 96 Raster Operation Units.

Radeon RX 5700 XT		225 Watts
Radeon RX 6800		250 Watts
	Difference: 25 Watts (11%)

Memory Bandwidth

The Radeon RX 6800 should in theory perform a small bit faster than the Radeon RX 5700 XT overall. (explain)

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

Texel Rate

The Radeon RX 6800 should be a lot (approximately 59%) faster with regards to AF than the Radeon RX 5700 XT. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 151200 (59%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6800 is a better choice, by far. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 60480 (59%)

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 max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
