Report a correction
Much more l2 cache 16 MB vs 8 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l2 cache per core 4 MB/core vs 2 MB/core 2x more l2 cache per core
Newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Newer Sep, 2008 vs Sep, 2007 Release date over a year later
