Radeon RX 5700 XT vs Radeon RX 6900 XT

Intro

Compare that to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this specific model. It features 5120 SPUs along with 320 Texture Address Units and 128 ROPs.

Radeon RX 5700 XT		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT will be a lot (more or less 127%) faster with regards to texture filtering than the Radeon RX 5700 XT. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 327200 (127%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is superior to the Radeon RX 5700 XT, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 130880 (127%)

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 largest amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
