GeForce GTX 1070 Ti vs Geforce GTX 780

Intro

The GeForce GTX 1070 Ti features core clock speeds of 1607 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2432 SPUs as well as 152 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Geforce GTX 780, which features a GPU core clock speed of 863 MHz, and 3072 MB of GDDR5 memory set to run at 1502 MHz through a 384-bit bus. It also features 2304 SPUs, 192 Texture Address Units, and 48 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
