PC vendors HP, Toshiba, and Gateway have all hopped onboard the Penryn bandwagon, and if a report over at CNet is to be believed, Dell is also going to be making the jump within a week or so from now by offering Intelís 45nm chips as an option on several of its notebooks.

Other than the lower heat and power usage these processors offer thanks to a new type of transistors with metal gates and high-k dielectrics, the new Penryn chips also offer performance bumps and a larger cache. No details are available regarding the choice of Penryn processors and the likely laptop models to feature them, but the high-end XPS range of laptops are likely candidates so if you were looking at purchasing one of those, you might want to wait a bit.
