The brand of laptop would help along with how old it is. Possibly it might have a dirty heatsink? Or maybe the fan. Is not ramping up.
But you have to remember ivy chips run very hot to start with and I am sure it is using a good but of CPU power along with the IGP built into the CPU die.
I would check your temperatures with core temp or speed fan......I do not think it is uncommon for your CPU to run at 90c.
If it throttling then a clog in the heatsink could be it or the fan
