Radeon RX 5600 vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which features a core clock speed of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 128-bit memory bus, and uses a 7 nm design. It is made up of 2048 SPUs, 128 TAUs, and 64 ROPs.

Radeon RX 5600		176000 Mtexels/sec
	Difference: 75904 (43%)

Pixel Rate

The Radeon RX 6600 XT should be much (more or less 43%) better at full screen anti-aliasing than the Radeon RX 5600, and able to handle higher resolutions while still performing well. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 37952 (43%)

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 maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
