Compare any two graphics cards:
VS

Radeon RX 6750 XT vs Radeon RX 6800

Intro

The Radeon RX 6750 XT has a core clock speed of 2150 MHz and a GDDR6 memory speed of 2250 MHz. It also features a 192-bit bus, and uses a 7 nm design. It features 2560 SPUs, 160 TAUs, and 64 ROPs.

Compare those specs to the Radeon RX 6800, which has core speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 3840 SPUs as well as 240 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800, in theory, should perform a little bit faster than the Radeon RX 6750 XT in general. (explain)

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

Texel Rate

The Radeon RX 6800 is a small bit (approximately 19%) faster with regards to anisotropic 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

The Radeon RX 6800 should be just a bit (more or less 19%) faster with regards to AA than the Radeon RX 6750 XT, and also should be capable of handling higher screen resolutions more effectively. (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 maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the 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 most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. 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 - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
