Compare any two graphics cards:
GeForce GTX 480 vs Radeon HD 3870 1GB
IntroThe GeForce GTX 480 uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR5 RAM works at a speed of 924 MHz on this specific model. It features 480 SPUs along with 60 TAUs and 48 Rasterization Operator Units.Compare all that to the Radeon HD 3870 1GB, which makes use of a 55 nm design. AMD has clocked the core speed at 775 MHz. The GDDR4 RAM is set to run at a frequency of 1125 MHz on this particular model. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 480 is 146% faster than the Radeon HD 3870 1GB in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 480 will be a lot (more or less 239%) better at AF than the Radeon HD 3870 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 480 is the winner, and very much so. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher 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 maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
