Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce GTX Titan
IntroThe GeForce GTX 780 Ti comes with a GPU clock speed of 875 MHz, and the 3072 MB of GDDR5 RAM runs at 1750 MHz through a 384-bit bus. It also is made up of 2880 Stream Processors, 240 TAUs, and 48 ROPs.
Compare that to the GeForce GTX Titan, which uses a 28 nm design. nVidia has clocked the core frequency at 837 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this particular model. It features 2688 SPUs as well as 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, in theory, should perform a small bit faster than the GeForce GTX Titan overall. (explain)
Texel RateThe GeForce GTX 780 Ti should be a bit (more or less 12%) better at AF than the GeForce GTX Titan. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 780 Ti is superior to the GeForce GTX Titan, though only just barely. (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 max amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
