Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 3850 X2
IntroThe Geforce GTX 670 features a core clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.Compare that to the Radeon HD 3850 X2, which comes with GPU core speed of 668 MHz, and 512 MB of GDDR3 memory set to run at 828 MHz through a 256-bit bus. It also is comprised of 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Geforce GTX 670 should theoretically be quite a bit superior to the Radeon HD 3850 X2 in general. (explain)
Texel RateThe Geforce GTX 670 will be a lot (about 379%) more effective at anisotropic filtering than the Radeon HD 3850 X2. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Geforce GTX 670 is the winner, by a large margin. (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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past 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, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
