Compare any two graphics cards:
GeForce GTX 460 (OEM) vs Radeon HD 3870 X2 1GB
IntroThe GeForce GTX 460 (OEM) makes use of a 40 nm design. nVidia has set the core speed at 650 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this particular card. It features 336 SPUs along with 56 TAUs and 32 ROPs.Compare those specs to the Radeon HD 3870 X2 1GB, which comes with core clock speeds of 825 MHz on the GPU, and 1126 MHz on the 1024 MB of GDDR4 RAM. It features 320(64x5) SPUs along with 16 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3870 X2 1GB should theoretically perform a lot faster than the GeForce GTX 460 (OEM) in general. (explain)
Texel RateThe GeForce GTX 460 (OEM) will be a lot (about 38%) more effective at AF than the Radeon HD 3870 X2 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 3870 X2 1GB is superior to the GeForce GTX 460 (OEM), by far. (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 largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
