Compare any two graphics cards:
GeForce GTX 480 vs Radeon HD 4550 512MB
IntroThe GeForce GTX 480 has a core clock frequency of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also makes use of a 384-bit bus, and makes use of a 40 nm design. It features 480 SPUs, 60 TAUs, and 48 ROPs.Compare all that to the Radeon HD 4550 512MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 600 MHz. The GDDR3 RAM is set to run at a speed of 800 MHz on this specific model. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 480 should be 1286% faster than the Radeon HD 4550 512MB in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 480 is a lot (approximately 775%) faster with regards to texture filtering than the Radeon HD 4550 512MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 480 is superior to the Radeon HD 4550 512MB, by a large margin. (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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few 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.
