Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 4850 X2 512MB
IntroThe GeForce GTX 470 features a core clock speed 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 is made up of 448 SPUs, 56 TAUs, and 40 ROPs.Compare all that to the Radeon HD 4850 X2 512MB, which uses a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR3 RAM runs at a frequency of 993 MHz on this model. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 470 should perform a little bit faster than the Radeon HD 4850 X2 512MB in general. (explain)
Texel RateThe Radeon HD 4850 X2 512MB will be a lot (approximately 47%) better at AF than the GeForce GTX 470. (explain)
Pixel RateThe GeForce GTX 470 will be a lot (approximately 21%) better at FSAA than the Radeon HD 4850 X2 512MB, and will 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, 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 amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
