Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 4850 X2 1GB
IntroThe GeForce GT 240 GDDR5 1GB uses a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this particular card. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 4850 X2 1GB, which comes with GPU clock speed of 625 MHz, and 1024 MB of GDDR3 memory running at 993 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4850 X2 1GB should be a lot faster than the GeForce GT 240 GDDR5 1GB overall. (explain)
Texel RateThe Radeon HD 4850 X2 1GB is a lot (about 184%) more effective at AF than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 4850 X2 1GB is superior to the GeForce GT 240 GDDR5 1GB, and very much so. (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 (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be processed in one second. This is calculated by multiplying the total number of texture units 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 applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
