Intel Core i7 6700HQ

Report a correction
Much higher turbo clock speed 3.5 GHz vs None Compared to all cpus, 3.5 GHz turbo clock speed is just OK
Much newer manufacturing process 14 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Lower typical power consumption 36.56W vs 52.81W More than 30% lower typical power consumption
More threads 8 vs 2 6 more threads
More cores 4 vs 2 Twice as many cores; run more applications at once
Better overclocked clock speed (Air) 3.51 GHz vs 2.8 GHz More than 25% better overclocked clock speed (Air)
Newer Jul, 2015 vs Jan, 2012 Release date over 3 years later
Better overclocked clock speed (Water) 3.5 GHz vs 2.8 GHz More than 25% better overclocked clock speed (Water)
Lower annual home energy cost 10.84 $/year vs 15.66 $/year More than 30% lower annual home energy cost
Lower annual commercial energy cost 39.42 $/year vs 56.94 $/year More than 30% lower annual commercial energy cost
