Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 580 3GB
IntroThe GeForce GTX 460 1GB uses a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 RAM runs at a frequency of 900 MHz on this specific model. It features 336 SPUs along with 56 TAUs and 32 ROPs.Compare those specifications to the GeForce GTX 580 3GB, which makes use of a 40 nm design. nVidia has set the core frequency at 772 MHz. The GDDR5 RAM is set to run at a frequency of 1002 MHz on this specific model. It features 512 SPUs along with 64 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 580 3GB should theoretically perform quite a bit faster than the GeForce GTX 460 1GB overall. (explain)
Texel RateThe GeForce GTX 580 3GB should be a lot (approximately 31%) better at AF than the GeForce GTX 460 1GB. (explain)
Pixel RateThe GeForce GTX 580 3GB is a lot (approximately 72%) faster with regards to AA than the GeForce GTX 460 1GB, and also will be able to handle higher screen resolutions while still performing well. (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 information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
