Much more l2 cache 2 MB vs 0.5 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Much better geekbench 3 AES single core score 32,500 MB/s vs 25,700 MB/s More than 25% better geekbench 3 AES single core score
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
More cores 2 vs 1 Twice as many cores; run more applications at once
Newer Jan, 2011 vs Jan, 2010 Release date a year later
