GeForce GTX 980 Ti vs GeForce RTX 2080 Ti

Intro

The GeForce GTX 980 Ti comes with a clock speed of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 384-bit memory bus, and makes use of a 28 nm design. It is made up of 2816 SPUs, 176 Texture Address Units, and 96 ROPs.

Compare all of that to the GeForce RTX 2080 Ti, which has core clock speeds of 1350 MHz on the GPU, and 14 MHz on the 11264 MB of GDDR6 memory. It features 4352 SPUs along with 272 TAUs and 88 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the bandwidth is, the lower the potential to get to the max fill rate.
