Compare any two graphics cards:
Geforce GTX 680 vs Geforce GTX 770
IntroThe Geforce GTX 680 uses a 28 nm design. nVidia has set the core speed at 1006 MHz. The GDDR5 memory runs at a frequency of 1502 MHz on this specific model. It features 1536 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.
Compare those specs to the Geforce GTX 770, which has a GPU core clock speed of 1046 MHz, and 2048 MB of GDDR5 RAM 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 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 770, in theory, should perform a bit faster than the Geforce GTX 680 overall. (explain)
Texel RateThe Geforce GTX 770 should be a little bit (more or less 4%) better at anisotropic filtering than the Geforce GTX 680. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Geforce GTX 770 is a better choice, though only just barely. (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 information (measured in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
