GeForce GTX 980 Ti vs Geforce GTX 1080 Ti

Intro

The GeForce GTX 980 Ti has a GPU core clock speed of 1000 MHz, and the 6144 MB of GDDR5 RAM runs at 1750 MHz through a 384-bit bus. It also is made up of 2816 SPUs, 176 Texture Address Units, and 96 Raster Operation Units.

Compare all of that to the Geforce GTX 1080 Ti, which uses a 16 nm design. nVidia has set the core speed at 1480 MHz. The GDDR5X memory runs at a frequency of 1376 MHz on this particular card. It features 3584 SPUs along with 224 TAUs and 88 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
