GeForce GTX Titan X vs Geforce GTX 780

Intro

The GeForce GTX Titan X comes with a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It is made up of 3072 SPUs, 192 Texture Address Units, and 96 ROPs.

Compare all of that to the Geforce GTX 780, which has a GPU core clock speed of 863 MHz, and 3072 MB of GDDR5 memory running at 1502 MHz through a 384-bit bus. It also is comprised of 2304 Stream Processors, 192 Texture Address Units, and 48 ROPs.

Geforce GTX 780 288384 MB/sec
Difference: 47616 (17%)

Texel Rate

The GeForce GTX Titan X should be just a bit (more or less 16%) better at AF than the Geforce GTX 780. (explain)

GeForce GTX Titan X 192000 Mtexels/sec
Geforce GTX 780 165696 Mtexels/sec
Difference: 26304 (16%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan X is the winner, by far. (explain)

GeForce GTX Titan X 96000 Mpixels/sec
Geforce GTX 780 41424 Mpixels/sec
Difference: 54576 (132%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
