Compare any two graphics cards:
GeForce GTX 980 Ti vs Nvidia Titan X
IntroThe GeForce GTX 980 Ti has a GPU core speed of 1000 MHz, and the 6144 MB of GDDR5 RAM is set to run at 1750 MHz through a 384-bit bus. It also is made up of 2816 Stream Processors, 176 Texture Address Units, and 96 ROPs.
Compare those specs to the Nvidia Titan X, which features a core clock speed of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit bus, and uses a 16 nm design. It is made up of 3584 SPUs, 224 TAUs, and 96 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The Nvidia Titan X should theoretically perform just a bit faster than the GeForce GTX 980 Ti overall. (explain)
Texel RateThe Nvidia Titan X is quite a bit (about 80%) more effective at anisotropic filtering than the GeForce GTX 980 Ti. (explain)
Pixel RateThe Nvidia Titan X will be quite a bit (more or less 42%) more effective at AA than the GeForce GTX 980 Ti, and will be capable of handling 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once 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 anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 reach the max fill rate.
