Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon HD 3870 512MB
IntroThe GeForce GTS 250 512MB makes use of a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 memory runs at a frequency of 1100 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 3870 512MB, which uses a 55 nm design. AMD has set the core speed at 775 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTS 250 512MB should theoretically be a lot better than the Radeon HD 3870 512MB overall. (explain)
Texel RateThe GeForce GTS 250 512MB will be much (approximately 281%) better at anisotropic filtering than the Radeon HD 3870 512MB. (explain)
Pixel RateThe Radeon HD 3870 512MB will be a bit (about 5%) faster with regards to AA than the GeForce GTS 250 512MB, and also capable of handling higher 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
