Compare any two graphics cards:
GeForce GTX 460 SE vs Radeon HD 4830 512MB
IntroThe GeForce GTX 460 SE comes with a core clock frequency of 650 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is comprised of 288 SPUs, 48 TAUs, and 32 Raster Operation Units.Compare all of that to the Radeon HD 4830 512MB, which uses a 55 nm design. AMD has set the core frequency at 575 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this particular model. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 460 SE should theoretically be a lot better than the Radeon HD 4830 512MB overall. (explain)
Texel RateThe GeForce GTX 460 SE is much (about 70%) better at anisotropic filtering than the Radeon HD 4830 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is a better choice, 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 maximum amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at 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 video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
