Compare any two graphics cards:
GeForce GTX 650 Ti 2GB vs Radeon HD 3870 X2 512MB
IntroThe GeForce GTX 650 Ti 2GB comes with a GPU clock speed of 928 MHz, and the 2048 MB of GDDR5 RAM runs at 1350 MHz through a 128-bit bus. It also is made up of 768 Stream Processors, 64 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon HD 3870 X2 512MB, which has a GPU core clock speed of 825 MHz, and 512 MB of GDDR3 memory running at 900 MHz through a 256-bit bus. It also features 320(64x5) Stream Processors, 16 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 3870 X2 512MB should perform quite a bit faster than the GeForce GTX 650 Ti 2GB in general. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB should be much (approximately 125%) faster with regards to texture filtering than the Radeon HD 3870 X2 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 3870 X2 512MB is superior to the GeForce GTX 650 Ti 2GB, 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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
