Compare any two graphics cards:
GeForce GTX 260 vs GeForce GTX 580
IntroThe GeForce GTX 260 comes with core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 192 SPUs as well as 64 Texture Address Units and 28 ROPs.Compare all that to the GeForce GTX 580, which uses a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 memory is set to run at a speed of 1002 MHz on this card. It features 512 SPUs as well as 64 Texture Address Units and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 580 should in theory be quite a bit faster than the GeForce GTX 260 overall. (explain)
Texel RateThe GeForce GTX 580 is a lot (about 34%) more effective at anisotropic filtering than the GeForce GTX 260. (explain)
Pixel RateThe GeForce GTX 580 will be quite a bit (more or less 130%) faster with regards to FSAA than the GeForce GTX 260, and will be able to handle higher screen resolutions more effectively. (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 largest amount of data (in units of MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
