Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti features a core clock frequency of 875 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 384-bit memory bus, and makes use of a 28 nm design. It features 2880 SPUs, 240 TAUs, and 48 Raster Operation Units.
Compare those specs to the GeForce GTX Titan, which comes with a core clock frequency of 837 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 384-bit memory bus, and makes use of a 28 nm design. It features 2688 SPUs, 224 Texture Address Units, and 48 ROPs.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
In theory, the GeForce GTX 780 Ti is 17% quicker than the GeForce GTX Titan in general, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 780 Ti should be a small bit (more or less 12%) more effective at anisotropic filtering than the GeForce GTX Titan. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 780 Ti is a better choice, 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 max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, 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 maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
