GeForce RTX 2080 Ti vs GeForce RTX 3070 Ti

Intro

The GeForce RTX 2080 Ti has a GPU core clock speed of 1350 MHz, and the 11264 MB of GDDR6 RAM runs at 1750 MHz through a 352-bit bus. It also features 4352 SPUs, 272 TAUs, and 88 Raster Operation Units.

Compare that to the GeForce RTX 3070 Ti, which features a GPU core clock speed of 1575 MHz, and 8192 MB of GDDR6X memory running at 1188 MHz through a 256-bit bus. It also is comprised of 6144 Stream Processors, 192 Texture Address Units, and 96 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
