Technically it can be said that the PS4 is the biggest leap, but let's look at it this way as well:
2 x 2 = 4 x 2 = 8 x 2 = 16.
2, 4, 8, 16.
Each have been increased by 2x, but the biggest leap is between 8 and 16 because there's a difference of 8.
I would say the exact same thing can be applied here.
