Compare any two graphics cards:
GeForce GTX 980 Ti vs GeForce GTX Titan Black
IntroThe GeForce GTX 980 Ti comes with a GPU clock speed of 1000 MHz, and the 6144 MB of GDDR5 RAM runs at 1750 MHz through a 384-bit bus. It also is comprised of 2816 Stream Processors, 176 TAUs, and 96 ROPs.
Compare all of that to the GeForce GTX Titan Black, which features core clock speeds of 889 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 RAM. It features 2880 SPUs along with 240 TAUs and 48 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Both cards have exactly the same memory bandwidth, so in theory they should have the same performance. (explain)
Texel RateThe GeForce GTX Titan Black will be quite a bit (about 21%) better at anisotropic filtering than the GeForce GTX 980 Ti. (explain)
Pixel RateThe GeForce GTX 980 Ti should be a lot (about 125%) more effective at anti-aliasing than the GeForce GTX Titan Black, and also able to handle higher resolutions more effectively. (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 max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
