Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti features a clock speed of 875 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 384-bit memory bus, and uses a 28 nm design. It is made up of 2880 SPUs, 240 TAUs, and 48 ROPs.
Compare that to the GeForce GTX Titan, which comes with a GPU core clock speed of 837 MHz, and 6144 MB of GDDR5 RAM running at 1502 MHz through a 384-bit bus. It also is made up of 2688 SPUs, 224 Texture Address Units, and 48 Raster Operation Units.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Performance-wise, the GeForce GTX 780 Ti should theoretically be just a bit superior to the GeForce GTX Titan in general. (explain)
Texel RateThe GeForce GTX 780 Ti is a small bit (approximately 12%) better at texture filtering than the GeForce GTX Titan. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 780 Ti is the winner, but 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.
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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 in one second. This figure is worked out by multiplying the total number of texture units of the card 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 applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
