GeForce GTX 1080 vs GeForce GTX Titan X

Intro

The GeForce GTX 1080 has a clock frequency of 1607 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 256-bit memory bus, and makes use of a 16 nm design. It features 2560 SPUs, 160 TAUs, and 64 ROPs.

Compare those specifications to the GeForce GTX Titan X, which features GPU core speed of 1000 MHz, and 12288 MB of GDDR5 RAM set to run at 1750 MHz through a 384-bit bus. It also is comprised of 3072 Stream Processors, 192 TAUs, and 96 ROPs.

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
