Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti features a GPU core clock speed of 875 MHz, and the 3072 MB of GDDR5 memory runs at 1750 MHz through a 384-bit bus. It also is comprised of 2880 Stream Processors, 240 Texture Address Units, and 48 ROPs.
Compare those specifications to the GeForce GTX Titan, which has a GPU core clock speed of 837 MHz, and 6144 MB of GDDR5 memory running at 1502 MHz through a 384-bit bus. It also features 2688 SPUs, 224 TAUs, and 48 Raster Operation Units.
(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 perform a little bit faster than the GeForce GTX Titan in general. (explain)
Texel RateThe GeForce GTX 780 Ti is a small bit (about 12%) better 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 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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
