Radeon RX 6650 XT 287072 MB/sec
Difference: 7840 (3%)

Texel Rate

The Radeon RX 6650 XT should be quite a bit (more or less 49%) better at anisotropic filtering than the Radeon RX 5600. (explain)

Radeon RX 6650 XT 263040 Mtexels/sec
Radeon RX 5600 176000 Mtexels/sec
Difference: 87040 (49%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is the winner, by a large margin. (explain)

Radeon RX 6650 XT 131520 Mpixels/sec
Radeon RX 5600 88000 Mpixels/sec
Difference: 43520 (49%)

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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video 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 write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
