In an evolutionary move forward, Intel unveiled today the first Penryn laptop processors. This makes the new platform a refresh of the Santa Rosa platform that was introduced last year. This new platform uses the Mobile Intel 965 express chipset, which comes with support for the Penryn processors, wireless connectivity and graphical subsystems.
Overall five new processors have been introduced. Among these there are four mainstream processors which use 45nm microprocessor architecture. This is the main change in this platform as it marks a move from 65nm to 45nm. This will help the mobile platform, as the new architecture will be more energy efficient and powerful. Though clock speed will be in the same range (1.9 to 2.7) the upper end processors will receive a 6 MB L2 cache as compared to the previous iteration of 2 and 4 MB.
Notebooks that utilize these processors have already been announced and will begin to appear soon.
In 2008 its going to be a big battle in between the amd and intel platform based notebooks as by the launch of phenom processors by Amd its going to be a big fight to watch. On the intel side people are still looking confused in buying either 45nm perlyn or 65nm architecture, some are waiting as 45nm processors are in thier early stage in Indian market and by talking to the people I can say that in this price sesitive market people will still play wait and watch for the coming two months or till the price of the 65nm gets a bit more shaken. A bit more of l2cache on the 45nm yorkfield or wolfdane processors introduced in comparison to the 65nm architecture will make some serious contribution to the multitasking field and will be a bit of relief for the vista users.
