Compare any two graphics cards:
GeForce GTX 580 3GB vs Geforce GTX 670
IntroThe GeForce GTX 580 3GB uses a 40 nm design. nVidia has clocked the core frequency at 772 MHz. The GDDR5 memory runs at a frequency of 1002 MHz on this model. It features 512 SPUs as well as 64 TAUs and 48 Rasterization Operator Units.Compare all that to the Geforce GTX 670, which has GPU core speed of 915 MHz, and 2048 MB of GDDR5 memory running at 1500 MHz through a 256-bit bus. It also features 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 580 3GB should theoretically perform a small bit faster than the Geforce GTX 670 overall. (explain)
Texel RateThe Geforce GTX 670 will be much (about 107%) faster with regards to texture filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateThe GeForce GTX 580 3GB should be a lot (about 27%) more effective at FSAA than the Geforce GTX 670, and also capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling 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 that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
