Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti features a GPU core speed of 875 MHz, and the 3072 MB of GDDR5 RAM runs at 1750 MHz through a 384-bit bus. It also features 2880 SPUs, 240 TAUs, and 48 ROPs.
Compare those specs to the GeForce GTX Titan, which uses a 28 nm design. nVidia has clocked the core frequency at 837 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this particular model. It features 2688 SPUs along with 224 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Performance-wise, the GeForce GTX 780 Ti should theoretically be just a bit better than the GeForce GTX Titan overall. (explain)
Texel RateThe GeForce GTX 780 Ti should be a little bit (about 12%) more effective at anisotropic filtering than the GeForce GTX Titan. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 780 Ti is the winner, but it probably won't make a huge difference. (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 largest amount of information (counted in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
