VS

Radeon RX 560 vs Radeon RX 6600 XT

Intro

The Radeon RX 560 features a GPU core speed of 1175 MHz, and the 4096 MB of GDDR5 memory runs at 1750 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 16 ROPs.

Compare all of that to the Radeon RX 6600 XT, which comes with core speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.

The Radeon RX 6600 XT should be much (approximately 235%) better at anisotropic 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

The Radeon RX 6600 XT is much (approximately 570%) better at anti-aliasing than the Radeon RX 560, and also will be capable of handling higher screen resolutions without slowing down too much. (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
