Radeon RX 570 vs Radeon RX 6600

Intro

Compare those specs to the Radeon RX 6600, which comes with GPU clock speed of 1626 MHz, and 8192 MB of GDDR6 RAM running at 1750 MHz through a 128-bit bus. It also features 1792 Stream Processors, 112 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon RX 570		150 Watts
	Difference: 18 Watts (14%)

Memory Bandwidth

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

Texel Rate

The Radeon RX 6600 should be a lot (approximately 22%) more effective at AF than the Radeon RX 570. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 32608 (22%)

Pixel Rate

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

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 66688 (178%)

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 max amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are processed per second. This 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
