The frequency characteristics of the first 45 nm intel desktop processors are already known. All is completely expected, the frequencies of these processors can approach 4.0 GHz if necessary.
Passage to the new technical process usually allow not only to increase the processors frequencies , but also to reduce the energy consumption level - for example, in the mobile segment this is the first advantage. Today we got new data about the frequency and thermal characteristics of mobile 45 nm processors penryn, whose announcement will takes place in the first quarter 2008.
The first party of penryn processors will be oriented to use in the updated mobile platform santa rosa, and therefore it will preserve the 800 MHz system bus. The dual core processors models penryn with 6 mb cache will operate at frequencies from 2.5 GHz to 2.8 GHz. Models with 3 mb cache in the second level will operate at frequencies from 2.1 GHz to 2.4 GHz. Focus attention, that penryn processors multiplier is equal to 0.5x.
In the second quarter 2008 , intel will announce penryn processors for montevina platform , which will use 1066 MHz system bus. Three models with 6 mb cache in the second level will operate at frequencies 2.53 GHz, 2.8 GHz and 3.06 GHz. The most remarkable, that the TDP level of these processors will lie within the 35 W, and for the model with 3.06 GHz frequency , will have a TDP level =44 W.
Three processors with 3 mb cache in the second level will also use the 1066 MHz system bus, their TDP level will not exceed 25 W, clock frequencies will be in the range from 2.13 GHz to 2.53 GHz. In the second quarter 2008 , the fraction of 45 nm processors in the mobile segment ( intel deliveries ) will compose 53%. Therefore, Intel will rapidly transfer the mobile platform to the use of 45 nm processors, and the reasons for this tendency can be understood, studying the energy characteristics data of those processors.
