Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon HD 4550 256MB
IntroThe GeForce GTX 460 2GB comes with core clock speeds of 675 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.Compare all of that to the Radeon HD 4550 256MB, which comes with core clock speeds of 600 MHz on the GPU, and 800 MHz on the 256 MB of DDR3 RAM. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 460 2GB should theoretically be a lot better than the Radeon HD 4550 256MB overall. (explain)
Texel RateThe GeForce GTX 460 2GB should be quite a bit (more or less 688%) faster with regards to AF than the Radeon HD 4550 256MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 460 2GB is superior to the Radeon HD 4550 256MB, 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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once 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 higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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. The figure is worked out 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
