Compare any two graphics cards:
VS

Radeon RX 590 vs Radeon RX 6600 XT

Intro

The Radeon RX 590 has clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Compare those specifications 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 memory. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT 160 Watts
Radeon RX 590 175 Watts
Difference: 15 Watts (9%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon RX 6600 XT should be a small bit (more or less 19%) better at anisotropic filtering than the Radeon RX 590. (explain)

Radeon RX 6600 XT 251904 Mtexels/sec
Radeon RX 590 211536 Mtexels/sec
Difference: 40368 (19%)

Pixel Rate

The Radeon RX 6600 XT should be much (more or less 168%) better at AA than the Radeon RX 590, and also capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6600 XT 125952 Mpixels/sec
Radeon RX 590 47008 Mpixels/sec
Difference: 78944 (168%)

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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
