Radeon RX 6750 XT vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which makes use of a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this specific model. It features 3840 SPUs along with 240 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 6800 should be a small 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 should be a bit (approximately 19%) faster with regards to 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

The Radeon RX 6800 will be just a bit (approximately 19%) more effective at full screen anti-aliasing than the Radeon RX 6750 XT, and also should be able to handle higher resolutions while still performing well. (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 max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per 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 clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
