Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti comes with core speeds of 875 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 RAM. It features 2880 SPUs as well as 240 Texture Address Units and 48 Rasterization Operator Units.
Compare that to the GeForce GTX Titan, which has clock speeds of 837 MHz on the GPU, and 1502 MHz on the 6144 MB of GDDR5 memory. It features 2688 SPUs along with 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 in theory be a bit faster than the GeForce GTX Titan overall. (explain)
Texel RateThe GeForce GTX 780 Ti will be just a bit (more or less 12%) more effective at AF than the GeForce GTX Titan. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 780 Ti is superior to the GeForce GTX Titan, though 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.
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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
