Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon HD 3850 X2
IntroThe GeForce GTX 460 2GB uses a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 memory runs at a speed of 900 MHz on this specific card. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.Compare those specs to the Radeon HD 3850 X2, which has a clock speed of 668 MHz and a GDDR3 memory speed of 828 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It is comprised of 320(64x5) SPUs, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the GeForce GTX 460 2GB should in theory be a little bit superior to the Radeon HD 3850 X2 overall. (explain)
Texel RateThe GeForce GTX 460 2GB will be much (approximately 77%) more effective at texture filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe GeForce GTX 460 2GB will be just a bit (more or less 1%) more effective at FSAA than the Radeon HD 3850 X2, and should be capable of handling higher 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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
