Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
More l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Newer manufacturing process 40 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Newer Jan, 2011 vs Jun, 2008 Release date over 2 years later
