The Celeron Chromebooks 2 were only slightly faster, maybe 15%. That's why I specifically called out the Intel Core CPU, not the Celeron. The Celeron N2840 is a "Bay Trail" Atom core, which nobody would willingly purchase. The state of the art CPU from that generation of Chromebooks was the 4th gen Core i3, a "Haswell" part that was more than twice as quick as that Celeron.
