The megahertzmythe… appeared a myth
Do you know the megahertzmythe yet” Only a handful of years ago lapsed straighten the assimilations capacity of a micro processor proportionally with the bell speed of it. How high the bell speed, how more fast the processor.
About that, that was for many the only comparisons point by the purchase of a processor. Especially Intel anticipated commercially on that reflex, firstly with the Pentium II and III, and later on with the Pentium 4 that already fast the border of 3 GHz crossed.
Apple and AMD could on that straight with difficulty compete with with Intel, all on that from benchmarks that the performances of this lower clocked only efficinter working processors just good or even better were then that of the fastest Intel-processors. The megahertzmythe was born. Finally Intel had to bow came towards wanted to unpack self also for the myth, because it against the borders of the Netburst micro architecture and it no longer with always higher bell speeds.
Today stretches the real bell speed of a processor hidden behind an artificial number. Even connoisseurs cannot larded name without just the bell speed of pakweg an Intel Core 2 Duo E6850 (it is 3 GHz otherwise). Next to bell speed yet other factors play with in the definition of the rating: Cachememory, interconnectiespeed and even energy-efficintie can in it processes become. AMD and Intel handle completely becomes then also each an own ratingsystem, through which is of only transparantie no talk, and the confusion.
Moreover can that everything do not veil that there in the base little changed is: a higher rating means simply a more capabele processor. And often means that also a higher bell speed. We are thus back by off.
More strongly even: the megahertzmythe appeared now self a myth. The some what analysts self today wonder is how scale bar a processor architecture is. In the particular AMD became/becomes for that heavily taken, because the langverwachte Barcelona quadcore-processors work will initially on only 2 GHz.
That is to be can offer much too little defense work at the newest generation Xeons of Intel. The quadcore Xeon - actual two at each other glued dualcore-processors - stretch now already at 3 GHz and the expectation is that thanks to the aboutschakeling to the 45 nanometer-production process 4 GHz within the possibilities lies. It falls to wait off or AMD native quadcore-architecture a such schaalbaarheidscurve will get, but the omens are meanwhile not good.
