Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti makes use of a 28 nm design. nVidia has clocked the core frequency at 875 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this card. It features 2880 SPUs along with 240 TAUs and 48 Rasterization Operator Units.
Compare those specs to the GeForce GTX Titan, which makes use of a 28 nm design. nVidia has clocked the core speed at 837 MHz. The GDDR5 memory is set to run at a frequency of 1502 MHz on this card. It features 2688 SPUs along with 224 TAUs and 48 Rasterization Operator Units.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The GeForce GTX 780 Ti should in theory be a bit faster than the GeForce GTX Titan overall. (explain)
Texel RateThe GeForce GTX 780 Ti is just a bit (about 12%) better at AF than the GeForce GTX Titan. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 780 Ti is superior to the GeForce GTX Titan, though not by far. (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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 fill 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 potential to reach the max fill rate.
