Compare any two graphics cards:
GeForce GTX 285 2GB vs GeForce GTX 570
IntroThe GeForce GTX 285 2GB features a GPU core 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 comprised of 240 Stream Processors, 80 TAUs, and 32 Raster Operation Units.Compare those specs to the GeForce GTX 570, which has a core clock frequency of 732 MHz and a GDDR5 memory speed of 950 MHz. It also makes use of a 320-bit memory bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 60 Texture Address Units, and 40 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 285 2GB should theoretically be a small bit superior to the GeForce GTX 570 in general. (explain)
Texel RateThe GeForce GTX 285 2GB should be just a bit (approximately 18%) faster with regards to texture filtering than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 is quite a bit (more or less 41%) more effective at anti-aliasing than the GeForce GTX 285 2GB, and capable of handling higher 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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported across 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 RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
