Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 680
IntroThe Geforce GTX 670 uses a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this specific model. It features 1344 SPUs along with 112 TAUs and 32 Rasterization Operator Units.
Compare those specifications to the Geforce GTX 680, which has a clock frequency of 1006 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is made up of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 680 should be a bit faster than the Geforce GTX 670 in general. (explain)
Texel RateThe Geforce GTX 680 is a lot (approximately 26%) more effective at texture filtering than the Geforce GTX 670. (explain)
Pixel RateThe Geforce GTX 680 is a little bit (about 10%) faster with regards to AA than the Geforce GTX 670, and should be able to handle higher screen 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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends 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.
