Radeon RX 5600 XT vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this particular model. It features 5120 SPUs along with 320 TAUs and 128 ROPs.

Radeon RX 5600 XT		344064 MB/sec
	Difference: 180224 (52%)

Texel Rate

The Radeon RX 6900 XT is much (more or less 195%) more effective at AF than the Radeon RX 5600 XT. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 386000 (195%)

Pixel Rate

The Radeon RX 6900 XT is quite a bit (approximately 165%) more effective at anti-aliasing than the Radeon RX 5600 XT, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 145600 (165%)

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 (counted in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
