Compare any two graphics cards:
Geforce GTX 770 vs Geforce GTX 780
IntroThe Geforce GTX 770 features a clock speed of 1046 MHz and a GDDR5 memory frequency of 1753 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.
Compare those specs to the Geforce GTX 780, which uses a 28 nm design. nVidia has set the core frequency at 863 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this model. It features 2304 SPUs along with 192 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 780 should theoretically perform much faster than the Geforce GTX 770 in general. (explain)
Texel RateThe Geforce GTX 780 is much (about 24%) faster with regards to AF than the Geforce GTX 770. (explain)
Pixel RateThe Geforce GTX 780 will be a lot (more or less 24%) faster with regards to AA than the Geforce GTX 770, and also should be able to handle higher screen resolutions while still performing well. (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 transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
