VS

Radeon RX 6750 XT vs Radeon RX 6800

Intro

The Radeon RX 6750 XT makes use of a 7 nm design. AMD has set the core speed at 2150 MHz. The GDDR6 RAM is set to run at a frequency of 2250 MHz on this particular model. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

Compare all of that to the Radeon RX 6800, which comes with GPU clock speed of 1700 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 3840 SPUs, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 6800 should be 19% faster than the Radeon RX 6750 XT in general, because of its greater bandwidth. (explain)

Radeon RX 6800 524288 MB/sec
Radeon RX 6750 XT 442368 MB/sec
Difference: 81920 (19%)

Texel Rate

The Radeon RX 6800 will be a small bit (about 19%) better at texture filtering than the Radeon RX 6750 XT. (explain)

Radeon RX 6800 408000 Mtexels/sec
Radeon RX 6750 XT 344000 Mtexels/sec
Difference: 64000 (19%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6800 is the winner, but it probably won't make a huge difference. (explain)

Radeon RX 6800 163200 Mpixels/sec
Radeon RX 6750 XT 137600 Mpixels/sec
Difference: 25600 (19%)

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: Bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
