Radeon RX 560 vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has set the core speed at 1968 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 560		80 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 80 Watts (100%)

Memory Bandwidth

Performance-wise, the Radeon RX 6600 XT should theoretically be much superior to the Radeon RX 560 in general. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 147456 (129%)

Texel Rate

The Radeon RX 6600 XT should be much (more or less 235%) better at texture filtering than the Radeon RX 560. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 176704 (235%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 XT is the winner, by far. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 107152 (570%)

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: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
