Front view of Intel Core i7 6700K

Reasons to consider the
Intel Core i7 6700K

Report a correction
Much higher clock speed 4 GHz vs 1 GHz 4x higher clock speed
Much newer manufacturing process 14 nm vs 65 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
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
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
Much better overclocked clock speed (Air) 4.61 GHz vs 1 GHz More than 4.5x better overclocked clock speed (Air)
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Newer Jul, 2015 vs Jul, 2006 Release date over 9 years later
More threads 8 vs 1 7 more threads
More cores 4 vs 1 3 more cores; run more applications at once
Much better overclocked clock speed (Water) 4.77 GHz vs 1 GHz More than 4.8x better overclocked clock speed (Water)
