Radeon RX 6750 XT vs Radeon RX 6800

Intro

The Radeon RX 6750 XT features a GPU clock speed of 2150 MHz, and the 12288 MB of GDDR6 RAM is set to run at 2250 MHz through a 192-bit bus. It also features 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Compare those specifications to the Radeon RX 6800, which has a core clock frequency of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 Texture Address Units, and 96 ROPs.

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

Texel Rate

The Radeon RX 6800 is a bit (approximately 19%) better at 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

The Radeon RX 6800 should be a bit (about 19%) faster with regards to FSAA than the Radeon RX 6750 XT, and able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
