Radeon RX 5600 XT vs Radeon RX 6800 XT

Intro

Compare all of that to the Radeon RX 6800 XT, which features a core clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and uses a 7 nm design. It is comprised of 4608 SPUs, 288 TAUs, and 128 Raster Operation Units.

Pixel Rate

The Radeon RX 6800 XT will be a lot (more or less 165%) better at full screen anti-aliasing than the Radeon RX 5600 XT, and capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6800 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 maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
