Intel Core i7 4770K

Report a correction
Much newer manufacturing process 22 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.5 GHz vs 2.13 GHz Around 65% higher clock speed
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Much better overclocked clock speed (Air) 4.48 GHz vs 2.69 GHz More than 65% better overclocked clock speed (Air)
Newer Jun, 2013 vs Jan, 2005 Release date over 8 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) 4.55 GHz vs 2.73 GHz More than 65% better overclocked clock speed (Water)
