Dell on Friday quietly updated its Latitude range to add Intel's 45 nanometer Penryn Core 2 Duos as an option. The 14-inch D630 and 15.4-inch D830 can both be custom-fitted with either a 2.5GHz or 2.6GHz Core 2 Duo on top of existing 65 nanometer chips. Both new optional Penryn CPUs offer 6MB of Level 2 cache, 800MHz FSB and lower power consumption which leads to improved battery life. The two pro systems otherwise appear to remain unchanged outside of prices. Either Latitude starts just below $1,400 with a 2GHz, previous-generation Core 2 Duo, 1GB of memory, an 80GB hard drive, and built-in Intel graphics. Adding the Penryn processors contributes $130 to the price for the 2.5GHz processor and $390 for the 2.6GHz edition.
