Compare any two graphics cards:
Geforce GTX 760 vs Geforce GTX 770
IntroThe Geforce GTX 760 features a GPU clock speed of 980 MHz, and the 2048 MB of GDDR5 memory is set to run at 1502 MHz through a 256-bit bus. It also features 1152 Stream Processors, 96 TAUs, and 32 Raster Operation Units.
Compare those specs to the Geforce GTX 770, which comes with a GPU core clock speed of 1046 MHz, and 2048 MB of GDDR5 memory running at 1753 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 770, in theory, should perform a little bit faster than the Geforce GTX 760 overall. (explain)
Texel RateThe Geforce GTX 770 should be quite a bit (about 42%) more effective at AF than the Geforce GTX 760. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Geforce GTX 770 is the winner, though not by far. (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 maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should 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 AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 potential to get to the maximum fill rate.
