GeForce GTX Titan X vs Geforce GTX 670

Intro

The GeForce GTX Titan X features a GPU core speed of 1000 MHz, and the 12288 MB of GDDR5 memory runs at 1750 MHz through a 384-bit bus. It also is comprised of 3072 SPUs, 192 Texture Address Units, and 96 Raster Operation Units.

Compare those specifications to the Geforce GTX 670, which features a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 memory running at 1500 MHz through a 256-bit bus. It also is comprised of 1344 SPUs, 112 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
