Radeon RX 560 vs Radeon RX 6800 XT

Intro

Compare those specifications to the Radeon RX 6800 XT, which features a clock speed of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit memory bus, and uses a 7 nm design. It is comprised of 4608 SPUs, 288 TAUs, and 128 ROPs.

Radeon RX 560		114688 MB/sec
	Difference: 409600 (357%)

Texel Rate

The Radeon RX 6800 XT is quite a bit (more or less 599%) better at AF than the Radeon RX 560. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 450400 (599%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6800 XT is the winner, and very much so. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 214800 (1143%)

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 (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
