Radeon RX 6500 XT vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which comes with GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also is made up of 5120 Stream Processors, 320 Texture Address Units, and 128 Raster Operation Units.

Radeon RX 6500 XT		147456 MB/sec
	Difference: 376832 (256%)

Texel Rate

The Radeon RX 6900 XT should be quite a bit (about 315%) better at AF than the Radeon RX 6500 XT. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 443200 (315%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6900 XT is the winner, by far. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 6500 XT		70400 Mpixels/sec
	Difference: 163200 (232%)

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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
