Radeon RX 6750 XT vs Radeon RX 6800

Intro

Compare those specs to the Radeon RX 6800, which features GPU clock speed of 1700 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also features 3840 Stream Processors, 240 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 will be 19% faster than the Radeon RX 6750 XT in general, because of its higher 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 a little bit (approximately 19%) more effective 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 resolution is important to you, then the Radeon RX 6800 is superior to the Radeon RX 6750 XT, but not by far. (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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
