GeForce RTX 2080 Ti vs GeForce RTX 3080

Intro

The GeForce RTX 2080 Ti makes use of a 12 nm design. nVidia has set the core speed at 1350 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this model. It features 4352 SPUs along with 272 Texture Address Units and 88 Rasterization Operator Units.

Compare those specifications to the GeForce RTX 3080, which features GPU core speed of 1440 MHz, and 10240 MB of GDDR6X RAM set to run at 1188 MHz through a 320-bit bus. It also is made up of 8704 SPUs, 272 Texture Address Units, and 96 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 bandwidth is, the lower the ability to reach the maximum fill rate.
