The reason is, i can show you some syntetic bench (category so loved by ARM community) in which Haswell is around 60% faster at the same clock vs. the previous generation in few workloads :). Say 10-50% means nothing without additional informations, the bar is predominantly to the left or to the right ?? and the bench suite utilized to evaluate the estimation is industry standard or ......shitty.
So better stay on the official slides ignoring the IPC for now.

No, obviously, this is the wrong thread......anyway ARM said many times to OEMs to stay careful with clock speed in A15 and A57, but never was heard....
Sure the power consumption/clock speed ramp of Krait is less steep, and this is an advantage shared with Intel.
