Why a 1.7GHz Centrino can be faster than 2.53GHz desktop processor ? I read this in a news. [?]
I thought I included that in with bus size; I meant both number of conduits and physical dimensions, but I suppose I could have elaborated. Chalk it up to laziness on my part.Originally posted by russ_watters
J-man, yeah. Laptops only. And you missed the primary factor in the efficiency difference between most chips: pipeline length. The reason the p4 is slower per clock cycle than the p3 is they doubled the length of the pipeline. It takes 20 clock cycles to process an individual instruction. There may be 20 different instructions in the pipeline, but when an operation depends on the results of another, the later operation has to wait before it can be run.
I could be wrong, but I believe it mainly has to do with the delay times.The reason the pipeline was lengthened is there is a relationship between how high a processor will clock and how long the pipeline is. Its a tradeoff (not sure why though).
It depends on what you mean by better, or what is better for your situation. The answer would vary depending on what is important for you be it price, size, power consumption, ips, ease of integration, instruction set, availability, etc.Originally posted by Saint
What is better than intel P4 ?

The Intel Xeon could be thought of as "better" because it allows duel-processor configuration.
