Radeon RX 6750 XT vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core frequency at 1700 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this particular card. 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

Theoretically speaking, the Radeon RX 6800 is 19% quicker than the Radeon RX 6750 XT in general, due to 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 is just a bit (about 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 will be just a bit (about 19%) more effective at full screen anti-aliasing than the Radeon RX 6750 XT, and also able to handle higher resolutions better. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
