Compare any two graphics cards:
Geforce GTX 770 vs Geforce GTX 780
IntroThe Geforce GTX 770 has a GPU core clock speed of 1046 MHz, and the 2048 MB of GDDR5 memory is set to run at 1753 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.
Compare all of that to the Geforce GTX 780, which has a core clock frequency of 863 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 2304 SPUs, 192 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 780, in theory, should perform much faster than the Geforce GTX 770 in general. (explain)
Texel RateThe Geforce GTX 780 will be a lot (approximately 24%) more effective at texture filtering than the Geforce GTX 770. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Geforce GTX 780 is the winner, and very much so. (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 data (in units of MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at 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 could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few 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.
