Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti has a core clock frequency of 875 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It features 2880 SPUs, 240 TAUs, and 48 ROPs.
Compare that to the GeForce GTX Titan, which features GPU core speed of 837 MHz, and 6144 MB of GDDR5 RAM set to run at 1502 MHz through a 384-bit bus. It also features 2688 Stream Processors, 224 TAUs, and 48 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The GeForce GTX 780 Ti, in theory, should perform just a bit faster than the GeForce GTX Titan in general. (explain)
Texel RateThe GeForce GTX 780 Ti will be just a bit (approximately 12%) more effective at texture filtering than the GeForce GTX Titan. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 780 Ti is the winner, though only just barely. (explain)
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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of 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.
