Compare any two graphics cards:
Geforce GTX 680 vs Geforce GTX 770
IntroThe Geforce GTX 680 features a core clock frequency of 1006 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It features 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.
Compare all of that to the Geforce GTX 770, which uses a 28 nm design. nVidia has clocked the core frequency at 1046 MHz. The GDDR5 memory runs at a speed of 1753 MHz on this specific card. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Geforce GTX 770 should theoretically be a bit superior to the Geforce GTX 680 overall. (explain)
Texel RateThe Geforce GTX 770 is a small bit (about 4%) faster with regards to anisotropic filtering than the Geforce GTX 680. (explain)
Pixel RateThe Geforce GTX 770 is a little bit (more or less 4%) faster with regards to AA than the Geforce GTX 680, and also capable of handling higher resolutions better. (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 megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 can be processed 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
