Radeon RX 6750 XT vs Radeon RX 6800 XT

Intro

The Radeon RX 6750 XT has a clock speed of 2150 MHz and a GDDR6 memory speed of 2250 MHz. It also uses a 192-bit bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 6800 XT, which comes with a core clock frequency of 1825 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 features 4608 SPUs, 288 Texture Address Units, and 128 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number 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 this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
