Much better geekbench 3 AES single core score 53,200 MB/s vs 25,700 MB/s More than 2x better geekbench 3 AES single core score
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
More cores 2 vs 1 Twice as many cores; run more applications at once
Better geekbench 3 Multi-Core score 1,127 vs 537 More than 2x better geekbench 3 Multi-Core score
Newer Aug, 2011 vs Jan, 2010 Release date over 1 years later
