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 makes use of a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2880 SPUs, 240 TAUs, and 48 ROPs.
Compare that to the GeForce GTX Titan, which features core speeds of 837 MHz on the GPU, and 1502 MHz on the 6144 MB of GDDR5 memory. It features 2688 SPUs along with 224 Texture Address Units and 48 Rasterization Operator Units.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The GeForce GTX 780 Ti should in theory perform a small bit faster than the GeForce GTX Titan in general. (explain)
Texel RateThe GeForce GTX 780 Ti will be a bit (more or less 12%) more effective at anisotropic filtering than the GeForce GTX Titan. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 780 Ti is the winner, but it probably won't make a huge difference. (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 information (counted in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
