Radeon RX 6750 XT vs Radeon RX 6800

Intro

The Radeon RX 6750 XT uses a 7 nm design. AMD has clocked the core speed at 2150 MHz. The GDDR6 RAM works at a speed of 2250 MHz on this particular model. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core frequency at 1700 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this particular model. It features 3840 SPUs as well as 240 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800 should theoretically be a little bit faster than the Radeon RX 6750 XT overall. (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 small bit (about 19%) faster with regards to AF 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 running with high levels of AA is important to you, then the Radeon RX 6800 is superior to the Radeon RX 6750 XT, though 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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
