Compare any two graphics cards:
GeForce GTX 285 1GB vs GeForce GTX 470
IntroThe GeForce GTX 285 1GB has a GPU clock speed of 648 MHz, and the 1024 MB of GDDR3 memory runs at 1242 MHz through a 512-bit bus. It also is comprised of 240 Stream Processors, 80 TAUs, and 32 Raster Operation Units.Compare those specs to the GeForce GTX 470, which features a core clock frequency of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also makes use of a 320-bit memory bus, and uses a 40 nm design. It features 448 SPUs, 56 TAUs, and 40 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 285 1GB should be 19% faster than the GeForce GTX 470 in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 285 1GB should be a lot (more or less 53%) faster with regards to anisotropic filtering than the GeForce GTX 470. (explain)
Pixel RateThe GeForce GTX 470 will be a small bit (about 17%) better at anti-aliasing than the GeForce GTX 285 1GB, and will be capable of handling higher screen resolutions without slowing down too much. (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

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to reach the max fill rate.
