Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs Radeon HD 4850 X2 512MB
IntroThe GeForce GTX 260 216SP 55 nm uses a 55 nm design. nVidia has set the core speed at 576 MHz. The GDDR3 memory works at a frequency of 999 MHz on this specific card. It features 216 SPUs as well as 72 TAUs and 28 Rasterization Operator Units.Compare those specifications to the Radeon HD 4850 X2 512MB, which comes with clock speeds of 625 MHz on the GPU, and 993 MHz on the 512 MB of GDDR3 RAM. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 4850 X2 512MB should be a bit faster than the GeForce GTX 260 216SP 55 nm in general. (explain)
Texel RateThe Radeon HD 4850 X2 512MB is much (about 21%) more effective at AF than the GeForce GTX 260 216SP 55 nm. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 4850 X2 512MB is a better choice, by far. (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 information (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a 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 number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
