Compare any two graphics cards:
GeForce GTX 650 Ti vs Radeon HD 3870 X2 1GB
IntroThe GeForce GTX 650 Ti uses a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this specific card. It features 768 SPUs as well as 64 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 3870 X2 1GB, which comes with GPU core speed of 825 MHz, and 1024 MB of GDDR4 RAM set to run at 1126 MHz through a 256-bit bus. It also is made up of 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3870 X2 1GB, in theory, should perform a lot faster than the GeForce GTX 650 Ti overall. (explain)
Texel RateThe GeForce GTX 650 Ti should be quite a bit (about 125%) faster with regards to anisotropic filtering than the Radeon HD 3870 X2 1GB. (explain)
Pixel RateThe Radeon HD 3870 X2 1GB will be a lot (approximately 78%) faster with regards to FSAA than the GeForce GTX 650 Ti, and also will be able to handle 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 information (measured in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 can be processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
