According to the rumor, the Tiger Lake Core i7 9750K will be based on the 10nm+ process and will be based on the LGA 1161 socket which will have 10 more pins than the 1151 socket that the current Coffee Lake series of CPUs are based on. The CPU will have a base clock of 4.5 GHz and will be able to boost to 5 GHz.

This is a rumor and has yet to be confirmed so do take this information with a grain of salt. Keep in mind that Coffee Lake CPUs will be released on the 5th of October so it is still pretty early to be speculating about the CPU that will be coming out in 2019.
