Compare any two graphics cards:
GeForce GTX 285 2GB vs GeForce GTX 570
IntroThe GeForce GTX 285 2GB has a GPU core clock speed of 648 MHz, and the 2048 MB of GDDR3 memory is set to run at 1242 MHz through a 512-bit bus. It also is made up of 240 Stream Processors, 80 Texture Address Units, and 32 Raster Operation Units.Compare those specs to the GeForce GTX 570, which features a clock frequency of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also uses a 320-bit bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 285 2GB should theoretically be a small bit better than the GeForce GTX 570 overall. (explain)
Texel RateThe GeForce GTX 285 2GB should be a small bit (more or less 18%) more effective at texture filtering than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 should be a lot (more or less 41%) more effective at full screen anti-aliasing than the GeForce GTX 285 2GB, and will be capable of handling higher 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: Bandwidth is the largest amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
