Radeon RX 5500 XT vs Radeon RX 6500 XT

Intro

Compare all that to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has set the core speed at 2200 MHz. The GDDR6 RAM is set to run at a frequency of 2250 MHz on this particular card. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

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

Texel Rate

The Radeon RX 5500 XT should be a small bit (more or less 7%) more effective at anisotropic filtering than the Radeon RX 6500 XT. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 10296 (7%)

Pixel Rate

The Radeon RX 6500 XT is much (more or less 28%) more effective at anti-aliasing than the Radeon RX 5500 XT, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 15456 (28%)

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 data (in units of MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at 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 graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
