Compare any two graphics cards:
GeForce 8800 GTS (G92) vs Radeon HD 4850 X2 1GB
IntroThe GeForce 8800 GTS (G92) comes with a GPU core clock speed of 650 MHz, and the 512 MB of GDDR3 RAM runs at 970 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 TAUs, and 16 ROPs.Compare that to the Radeon HD 4850 X2 1GB, which has a clock speed of 625 MHz and a GDDR3 memory speed of 993 MHz. It also makes use of a 256-bit bus, and uses a 55 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4850 X2 1GB should in theory be much better than the GeForce 8800 GTS (G92) in general. (explain)
Texel RateThe Radeon HD 4850 X2 1GB will be a small bit (more or less 20%) more effective at AF than the GeForce 8800 GTS (G92). (explain)
Pixel RateThe Radeon HD 4850 X2 1GB will be a lot (more or less 92%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTS (G92), and also capable of handling higher resolutions while still performing well. (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

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once 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, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
