The dynamic speed technology in desktop bloomfield processors will allow a dynamic increase in the frequency of the separately loaded core by 133-266 MHz, which corresponds to only two multiplier steps or 5-10% frequency boost . In this case a phenomenal acceleration of single-threaded applications can not be observed .
Nehalem generation processors will obtain the intermediate TDP values , which correspond to each energy state, determined by the multiplier value . If the processor has a TDP not more than 130 W, then from this value 20 W are for (un-core) the built-in memory controller and cache in the third level. TDP Value for this processor part remain constant for any energy state, and here the TDP value for the core changes proportional to the multiplier. For example, TDP value for core i7 940 (2.93 GHz) model varies in the limits from 37 to 130 W.
Within the turbo- regime , the processor does not have the right to exceed the limits of its thermal packet.
Which is interesting, the mobile processors clarksfield and Auburndale will more aggressively increase their frequency within the dynamic speed technology. According to our associates, increase in the frequency can reach 50% and above. Obviously, the mobile representatives of nehalem architecture can compensate such jumps of frequency by some functions of energy-economy.
