Compare any two graphics cards:
GeForce GTX Titan vs Geforce GTX 780
IntroThe GeForce GTX Titan comes with a core clock speed of 837 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 2688 SPUs, 224 Texture Address Units, and 48 ROPs.
Compare those specifications to the Geforce GTX 780, which has core speeds of 863 MHz on the GPU, and 1502 MHz on the 3072 MB of GDDR5 RAM. It features 2304 SPUs along with 192 TAUs and 48 ROPs.

Grand Theft Auto V | 1920x1080 | Very High
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Both cards have the exact same memory bandwidth, so theoretically they should have the same performance. (explain)
Texel RateThe GeForce GTX Titan is a bit (more or less 13%) more effective at AF than the Geforce GTX 780. (explain)
Pixel RateThe Geforce GTX 780 will be a bit (more or less 3%) faster with regards to AA than the GeForce GTX Titan, and also should be able to handle higher screen resolutions more effectively. (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 (in units of MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
