GeForce RTX 2080 vs GeForce RTX 2080 Ti

Intro

The GeForce RTX 2080 uses a 12 nm design. nVidia has set the core frequency at 1515 MHz. The GDDR6 memory runs at a frequency of 14 MHz on this particular card. It features 2944 SPUs as well as 184 TAUs and 64 Rasterization Operator Units.

Compare those specifications to the GeForce RTX 2080 Ti, which features GPU core speed of 1350 MHz, and 11264 MB of GDDR6 RAM running at 14 MHz through a 352-bit bus. It also is made up of 4352 Stream Processors, 272 Texture Address Units, and 88 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
