Radeon RX 6750 XT vs Radeon RX 6800 XT

Intro

The Radeon RX 6750 XT comes with a GPU core clock speed of 2150 MHz, and the 12288 MB of GDDR6 memory is set to run at 2250 MHz through a 192-bit bus. It also features 2560 SPUs, 160 TAUs, and 64 ROPs.

Compare those specifications to the Radeon RX 6800 XT, which features a core clock speed of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit memory bus, and uses a 7 nm design. It features 4608 SPUs, 288 Texture Address Units, and 128 ROPs.

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

Texel Rate

The Radeon RX 6800 XT will be a lot (about 53%) more effective at 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 a large margin. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
