Report a correction
Much newer manufacturing process 32 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better geekbench 2 (32-bit) score 4,764 vs 1,540 More than 3x better geekbench 2 (32-bit) score
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much better performance per watt 20.44 pt/W vs 1.3 pt/W More than 15.8x better performance per watt
Higher clock speed 2.5 GHz vs 2.1 GHz Around 20% higher clock speed
Much higher Maximum operating temperature 100 °C vs 55 °C More than 80% higher Maximum operating temperature
Significantly better PassMark (Single core) score 1,493 vs 640 More than 2.2x better PassMark (Single core) score
Much more l3 cache per core 1.5 MB/core vs 0.25 MB/core 6x more l3 cache per core
