GeForce GTX 1070 Ti vs GeForce RTX 2080 Ti

Intro

The GeForce GTX 1070 Ti has a core clock frequency of 1607 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 16 nm design. It features 2432 SPUs, 152 TAUs, and 64 ROPs.

Compare that to the GeForce RTX 2080 Ti, which comes with clock speeds of 1350 MHz on the GPU, and 1750 MHz on the 11264 MB of GDDR6 memory. It features 4352 SPUs as well as 272 TAUs and 88 Rasterization Operator Units.

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling 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 the video card could possibly write to its 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 clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
