Radeon RX 6500 XT vs Radeon RX 6800

Intro

Compare that to the Radeon RX 6800, which uses a 7 nm design. AMD has clocked the core frequency at 1700 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this particular card. It features 3840 SPUs along with 240 TAUs and 96 Rasterization Operator Units.

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

Texel Rate

The Radeon RX 6800 will be quite a bit (about 190%) better at anisotropic filtering than the Radeon RX 6500 XT. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 267200 (190%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6800 is a better choice, by far. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 6500 XT		70400 Mpixels/sec
	Difference: 92800 (132%)

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 data (in units of MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many 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.
