Compare any two graphics cards:
GeForce GTX 980 Ti vs Nvidia Titan X
IntroThe GeForce GTX 980 Ti makes use of a 28 nm design. nVidia has set the core speed at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this specific model. It features 2816 SPUs along with 176 Texture Address Units and 96 Rasterization Operator Units.
Compare that to the Nvidia Titan X, which uses a 16 nm design. nVidia has clocked the core speed at 1417 MHz. The GDDR5X memory works at a frequency of 1251 MHz on this card. It features 3584 SPUs along with 224 Texture Address Units and 96 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Performance-wise, the Nvidia Titan X should in theory be a lot superior to the GeForce GTX 980 Ti overall. (explain)
Texel RateThe Nvidia Titan X is a lot (more or less 80%) faster with regards to AF than the GeForce GTX 980 Ti. (explain)
Pixel RateThe Nvidia Titan X is much (about 42%) faster with regards to anti-aliasing than the GeForce GTX 980 Ti, and also should be capable of handling higher screen resolutions better. (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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be 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 higher the texel rate, 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 most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
