Reasons to consider the
Intel Core i7 3770K

Report a correction
Much higher turbo clock speed 3.9 GHz vs 0 GHz Compared to all cpus, 3.9 GHz turbo clock speed is just OK
Is unlocked Yes vs No Somewhat common; An unlocked multiplier allows for easier overclocking
Significantly higher clock speed 3.5 GHz vs 2.5 GHz 40% higher clock speed
Much newer manufacturing process 22 nm vs 45 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
Much better overclocked clock speed (Air) 4.69 GHz vs 2.84 GHz More than 65% better overclocked clock speed (Air)
Significantly more l3 cache per core 2 MB/core vs 1 MB/core 2x more l3 cache per core
Higher Maximum operating temperature 67.4 °C vs 55 °C Around 25% higher Maximum operating temperature
Much better overclocked clock speed (Water) 4.8 GHz vs 2.5 GHz More than 90% better overclocked clock speed (Water)
Newer Apr, 2012 vs Feb, 2011 Release date over 1 years later
Lower annual commercial energy cost 112.39 $/year vs 122.64 $/year Around 10% lower annual commercial energy cost

Much more l2 cache 6 MB vs 1 MB 6x more l2 cache; more data can be stored in the l2 cache for quick access later
Supports more CPUs in SMP configuration 4 vs 1 3 supports more CPUs in SMP configuration
More cores 12 vs 4 Three times as many cores; run more applications at once
More l3 cache 12 MB vs 8 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
More threads 12 vs 8 4 more threads
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Significantly lower annual home energy cost 33.73 $/year vs 42.19 $/year More than 20% lower annual home energy cost
