Radeon RX 6750 XT vs Radeon RX Vega 56

Intro

The Radeon RX 6750 XT has a clock frequency of 2150 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 192-bit memory bus, and uses a 7 nm design. It features 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Compare all of that to the Radeon RX Vega 56, which makes use of a 14 nm design. AMD has clocked the core frequency at 1156 MHz. The HBM2 memory works at a frequency of 1600 MHz on this particular model. It features 3584 SPUs as well as 224 Texture Address Units and 64 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many 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.
