Compare any two graphics cards:
VS

Radeon RX 5500 XT vs Radeon RX 6600 XT

Intro

The Radeon RX 5500 XT comes with core clock speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Compare those specs to the Radeon RX 6600 XT, which comes with core clock 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 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT 130 Watts
Radeon RX 6600 XT 160 Watts
Difference: 30 Watts (23%)

Memory Bandwidth

The Radeon RX 6600 XT should theoretically be just a bit faster than the Radeon RX 5500 XT in general. (explain)

Radeon RX 6600 XT 262144 MB/sec
Radeon RX 5500 XT 229376 MB/sec
Difference: 32768 (14%)

Texel Rate

The Radeon RX 6600 XT should be a lot (approximately 67%) more effective at anisotropic filtering than the Radeon RX 5500 XT. (explain)

Radeon RX 6600 XT 251904 Mtexels/sec
Radeon RX 5500 XT 151096 Mtexels/sec
Difference: 100808 (67%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6600 XT is the winner, and very much so. (explain)

Radeon RX 6600 XT 125952 Mpixels/sec
Radeon RX 5500 XT 54944 Mpixels/sec
Difference: 71008 (129%)

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 MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
