GeForce GTX 1080 vs GeForce GTX Titan X

Intro

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

Compare all that to the GeForce GTX Titan X, which comes with GPU core speed of 1000 MHz, and 12288 MB of GDDR5 RAM running at 1750 MHz through a 384-bit bus. It also is comprised of 3072 Stream Processors, 192 TAUs, and 96 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
