Compare any two graphics cards:
GeForce GTX 280 vs Geforce GTX 680
IntroThe GeForce GTX 280 features a clock speed of 602 MHz and a GDDR3 memory speed of 1107 MHz. It also makes use of a 512-bit bus, and makes use of a 65 nm design. It features 240 SPUs, 80 TAUs, and 32 ROPs.Compare those specs to the Geforce GTX 680, which has GPU clock speed of 1006 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also features 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Geforce GTX 680, in theory, should be a lot faster than the GeForce GTX 280 in general. (explain)
Texel RateThe Geforce GTX 680 should be much (about 167%) faster with regards to anisotropic filtering than the GeForce GTX 280. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Geforce GTX 680 is a better choice, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
