Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti features a GPU clock speed of 875 MHz, and the 3072 MB of GDDR5 memory is set to run at 1750 MHz through a 384-bit bus. It also is comprised of 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.
Compare all of that to the GeForce GTX Titan, which features a GPU core clock speed of 837 MHz, and 6144 MB of GDDR5 RAM set to run at 1502 MHz through a 384-bit bus. It also is comprised of 2688 Stream Processors, 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.
Theoretically speaking, the GeForce GTX 780 Ti should be a small bit faster than the GeForce GTX Titan in general. (explain)
Texel RateThe GeForce GTX 780 Ti is a small bit (approximately 12%) more effective at texture filtering than the GeForce GTX Titan. (explain)
Pixel RateThe GeForce GTX 780 Ti is a little bit (more or less 5%) more effective at FSAA than the GeForce GTX Titan, and will be able to handle higher screen 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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
