Compare any two graphics cards:
GeForce GTX 460 (OEM) vs Radeon HD 3850 X2
IntroThe GeForce GTX 460 (OEM) makes use of a 40 nm design. nVidia has set the core frequency at 650 MHz. The GDDR5 memory works at a speed of 850 MHz on this specific model. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.Compare all that to the Radeon HD 3850 X2, which comes with a core clock speed of 668 MHz and a GDDR3 memory speed of 828 MHz. It also makes use of a 256-bit bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the GeForce GTX 460 (OEM) should in theory be a little bit superior to the Radeon HD 3850 X2 overall. (explain)
Texel RateThe GeForce GTX 460 (OEM) should be a lot (about 70%) better at texture filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe Radeon HD 3850 X2 should be a bit (approximately 3%) faster with regards to AA than the GeForce GTX 460 (OEM), and also should be capable of handling higher screen resolutions without slowing down too much. (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 max amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
