Radeon RX 6750 XT vs Radeon RX 6800 XT

Intro

Compare all that to the Radeon RX 6800 XT, which has GPU core speed of 1825 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also is comprised of 4608 Stream Processors, 288 TAUs, and 128 Raster Operation Units.

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

Texel Rate

The Radeon RX 6800 XT should be a lot (more or less 53%) faster with regards to AF 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 using a high screen resolution is important to you, then the Radeon RX 6800 XT is superior to the Radeon RX 6750 XT, and very much so. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied 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 figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
