Compare any two graphics cards:
Geforce GTX 770 vs Geforce GTX 780
IntroThe Geforce GTX 770 features a core clock frequency 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 all that to the Geforce GTX 780, which features a core clock frequency of 863 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 384-bit memory bus, and makes use of a 28 nm design. It features 2304 SPUs, 192 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Geforce GTX 780 should perform a lot faster than the Geforce GTX 770 overall. (explain)
Texel RateThe Geforce GTX 780 should be quite a bit (approximately 24%) better at AF than the Geforce GTX 770. (explain)
Pixel RateThe Geforce GTX 780 should be quite a bit (approximately 24%) faster with regards to AA than the Geforce GTX 770, and also should be capable of handling 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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core 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 one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
