Radeon RX 570 vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which has a clock speed of 2200 MHz and a GDDR6 memory frequency of 2250 MHz. It also uses a 64-bit bus, and uses a 6 nm design. It is comprised of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon RX 570		150 Watts
	Difference: 43 Watts (40%)

Memory Bandwidth

The Radeon RX 570 should in theory be quite a bit faster than the Radeon RX 6500 XT in general. (explain)

Radeon RX 570		229376 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 81920 (56%)

Texel Rate

The Radeon RX 570 is a small bit (more or less 6%) better at texture filtering than the Radeon RX 6500 XT. (explain)

Radeon RX 570		149504 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 8704 (6%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6500 XT is the winner, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 33024 (88%)

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 largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, 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 most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
