Front view of Intel Core i5 6442EQ

Reasons to consider the
Intel Core i5 6442EQ

Report a correction
Significantly newer manufacturing process 14 nm vs 22 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More l3 cache 6 MB vs 3 MB 2x more l3 cache; more data can be stored in the l3 cache for quick access later
Higher GPU clock speed 350 MHz vs 200 MHz 75% higher GPU clock speed
More cores 4 vs 2 Twice as many cores; run more applications at once
Better overclocked clock speed (Water) 2.7 GHz vs 1.9 GHz More than 40% better overclocked clock speed (Water)
