Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti has a core clock frequency of 875 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It is comprised of 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.
Compare all of that to the GeForce GTX Titan, which has GPU core speed of 837 MHz, and 6144 MB of GDDR5 memory set to run at 1502 MHz through a 384-bit bus. It also is made up of 2688 SPUs, 224 TAUs, and 48 ROPs.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The GeForce GTX 780 Ti should theoretically perform just a bit faster than the GeForce GTX Titan overall. (explain)
Texel RateThe GeForce GTX 780 Ti should be just a bit (approximately 12%) better at texture filtering than the GeForce GTX Titan. (explain)
Pixel RateThe GeForce GTX 780 Ti is a bit (about 5%) better at anti-aliasing than the GeForce GTX Titan, and also able to handle higher screen resolutions without losing too much performance. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 are applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
