Report a correction
Significantly higher clock speed 2.5 GHz vs 1.8 GHz Around 40% higher clock speed
Is hyperthreaded Yes vs No Somewhat common; Maximizes usage of each CPU core
Newer manufacturing process 22 nms vs 32 nms A newer manufacturing process allows for a more powerful, yet cooler running processor
More l3 cache 3 MB vs 2 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
More number of displays supported 3 vs 2 1 more number of displays supported
More threads 4 vs 2 Twice as many threads
Supports more RAM 32,768 MB vs 16,384 MB Supports 2x more RAM
Better PassMark (Single core) score 1,313 vs 867 More than 50% better PassMark (Single core) score
Better PassMark score 3,342 vs 1,515 Around 2.2x better PassMark score
Better overclocked clock speed (Air) 2.54 GHz vs 1.8 GHz More than 40% better overclocked clock speed (Air)
More l3 cache per core 1.5 MB/core vs 1 MB/core 50% more l3 cache per core
Better geekbench (32-bit) score 4,002 vs 2,227 Around 80% better geekbench (32-bit) score
Slightly better turbo clock speed 1,100 MHz vs 1,050 MHz Around 5% better turbo clock speed
Better performance per watt 13.09 pt/W vs 7.04 pt/W More than 85% better performance per watt
Significantly better overclocked clock speed (Water) 2.5 GHz vs 1.8 GHz Around 40% better overclocked clock speed (Water)
