Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon HD 4550 256MB
IntroThe GeForce GTX 460 2GB has a GPU clock speed of 675 MHz, and the 2048 MB of GDDR5 RAM runs at 900 MHz through a 256-bit bus. It also features 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.Compare that to the Radeon HD 4550 256MB, which comes with a clock frequency of 600 MHz and a DDR3 memory speed of 800 MHz. It also uses a 64-bit memory bus, and uses a 55 nm design. It is made up of 80(16x5) SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 460 2GB should be a lot faster than the Radeon HD 4550 256MB overall. (explain)
Texel RateThe GeForce GTX 460 2GB is much (more or less 688%) better at texture filtering than the Radeon HD 4550 256MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 460 2GB is a better choice, by far. (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

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen 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 a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
