Compare any two graphics cards:
GeForce GTX Titan Black vs Nvidia Titan X
IntroThe GeForce GTX Titan Black features core clock speeds of 889 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 memory. It features 2880 SPUs as well as 240 TAUs and 48 Rasterization Operator Units.
Compare all of that to the Nvidia Titan X, which comes with a core clock speed of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also features a 384-bit bus, and uses a 16 nm design. It is made up of 3584 SPUs, 224 Texture Address Units, and 96 Raster Operation Units.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
In theory, the Nvidia Titan X should be a small bit faster than the GeForce GTX Titan Black overall. (explain)
Texel RateThe Nvidia Titan X will be quite a bit (more or less 49%) faster with regards to texture filtering than the GeForce GTX Titan Black. (explain)
Pixel RateThe Nvidia Titan X will be much (about 219%) faster with regards to full screen anti-aliasing than the GeForce GTX Titan Black, and should be able to handle higher 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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
