GeForce RTX 2080 Ti vs GeForce RTX 3070 Ti

Intro

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

Compare all of that to the GeForce RTX 3070 Ti, which features a GPU core clock speed of 1575 MHz, and 8192 MB of GDDR6X RAM running at 1188 MHz through a 256-bit bus. It also is made up of 6144 SPUs, 192 Texture Address Units, and 96 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
