VS

Geforce GTX 1080 Ti vs Radeon RX 6950 XT

Intro

The Geforce GTX 1080 Ti comes with a GPU core clock speed of 1480 MHz, and the 11264 MB of GDDR5X memory runs at 1376 MHz through a 352-bit bus. It also is comprised of 3584 SPUs, 224 TAUs, and 88 ROPs.

Compare those specs to the Radeon RX 6950 XT, which has a GPU core clock speed of 1925 MHz, and 16384 MB of GDDR6 memory running at 2250 MHz through a 256-bit bus. It also features 5120 Stream Processors, 320 TAUs, and 128 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 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 reach the maximum fill rate.
