Radeon RX 6700 XT vs Radeon RX 6750 XT

Intro

The Radeon RX 6700 XT has a clock speed of 2321 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 192-bit bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Compare that to the Radeon RX 6750 XT, which comes with core clock speeds of 2150 MHz on the GPU, and 2250 MHz on the 12288 MB of GDDR6 memory. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
