Compare any two graphics cards:
GeForce GTX 460 (OEM) vs GeForce GTX 580 3GB
IntroThe GeForce GTX 460 (OEM) features core speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 TAUs and 32 ROPs.Compare those specs to the GeForce GTX 580 3GB, which comes with GPU core speed of 772 MHz, and 3072 MB of GDDR5 memory set to run at 1002 MHz through a 384-bit bus. It also features 512 SPUs, 64 TAUs, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 580 3GB is 77% quicker than the GeForce GTX 460 (OEM) overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 580 3GB will be a lot (approximately 36%) faster with regards to AF than the GeForce GTX 460 (OEM). (explain)
Pixel RateThe GeForce GTX 580 3GB is a lot (about 78%) faster with regards to FSAA than the GeForce GTX 460 (OEM), and should be able to handle 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 max amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
