The site Coolaler managed to get their hands on what appears to be a prototype mobile Core 2 Duo-based architecture Penryn.
This model clocked at 2.8 GHz is at the highest rating. It has 6 MB cache in total. Two others at 2.5 and 2.6 GHz feature identical cache size. However, the 2.1 and 2.4 GHz versions will come with half L2 cache.
These products are scheduled for the beginning 2008, and possibly, Apple refreshes its range of MacBook Pro at the Macworld Expo in San Francisco with these.
