GeForce RTX 2080 SUPER vs Radeon RX 6950 XT

Intro

The GeForce RTX 2080 SUPER features a GPU clock speed of 1650 MHz, and the 8192 MB of GDDR6 memory is set to run at 1937 MHz through a 256-bit bus. It also features 3072 Stream Processors, 192 Texture Address Units, and 64 ROPs.

Compare those specs to the Radeon RX 6950 XT, which comes with a clock frequency of 1925 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 256-bit memory bus, and uses a 7 nm design. It features 5120 SPUs, 320 TAUs, and 128 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better 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 maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
