Compare any two graphics cards:
GeForce GTX Titan vs Geforce GTX 780
IntroThe GeForce GTX Titan features a core clock frequency of 837 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 384-bit bus, and uses a 28 nm design. It is comprised of 2688 SPUs, 224 TAUs, and 48 Raster Operation Units.
Compare those specifications to the Geforce GTX 780, which makes use of a 28 nm design. nVidia has clocked the core speed at 863 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this specific model. It features 2304 SPUs along with 192 TAUs and 48 Rasterization Operator Units.

Grand Theft Auto V | 1920x1080 | Very High
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Both cards have exactly the same memory bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe GeForce GTX Titan should be just a bit (about 13%) better at AF than the Geforce GTX 780. (explain)
Pixel RateThe Geforce GTX 780 will be a bit (about 3%) more effective at full screen anti-aliasing than the GeForce GTX Titan, and also should be able to handle higher resolutions without slowing down too much. (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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be processed 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 higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
