GeForce RTX 2080 Ti vs Radeon RX 6950 XT

Intro

The GeForce RTX 2080 Ti uses a 12 nm design. nVidia has clocked the core speed at 1350 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this specific model. It features 4352 SPUs along with 272 Texture Address Units and 88 Rasterization Operator Units.

Compare those specs to the Radeon RX 6950 XT, which uses a 7 nm design. AMD has clocked the core speed at 1925 MHz. The GDDR6 memory works at a speed of 2250 MHz on this specific card. It features 5120 SPUs as well as 320 Texture Address Units and 128 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
