GeForce GTX 980 Ti vs Geforce GTX 780

Intro

The GeForce GTX 980 Ti uses a 28 nm design. nVidia has set the core speed at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this specific model. It features 2816 SPUs along with 176 TAUs and 96 Rasterization Operator Units.

Compare all that to the Geforce GTX 780, which makes use of a 28 nm design. nVidia has clocked the core speed at 863 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this model. It features 2304 SPUs as well as 192 TAUs and 48 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video 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 amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
