Not easy. Most tablets have several high performance cores, low power
cores, GPU cores, etc.
So there is little you can do to compare them based on clock speeds.
Further of course, most (all?) tablets are ARM based (including Apple
iPad).
ARM instructions are processed differently. So what an i5 or i7 will do
in 2 clock cycles is often more (but not always) than what an ARM
processor does in 2 clock cycles. ARM also make up for this with many
clever tricks.

Get an iPad Pro and don`t worry about it.
