Front view of Intel Core i7 4770

Reasons to consider the
Intel Core i7 4770

Report a correction
Much newer manufacturing process 22 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.4 GHz vs 2 GHz 70% higher clock speed
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) 3.85 GHz vs 2 GHz Around 95% better overclocked clock speed (Air)
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) 4.01 GHz vs 2 GHz More than 2x better overclocked clock speed (Water)
