Radeon RX 6750 XT vs Radeon RX 6800 XT

Intro

Compare all of that to the Radeon RX 6800 XT, which has core speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 4608 SPUs as well as 288 Texture Address Units and 128 Rasterization Operator Units.

Radeon RX 6750 XT		442368 MB/sec
	Difference: 81920 (19%)

Texel Rate

The Radeon RX 6800 XT is quite a bit (about 53%) faster with regards to anisotropic filtering than the Radeon RX 6750 XT. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon RX 6750 XT		344000 Mtexels/sec
	Difference: 181600 (53%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is superior to the Radeon RX 6750 XT, by far. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 96000 (70%)

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 information (measured in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core 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 many 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.
