The i9-9980HK (released April 2019) in the 16" 2019 Macbook Pro looks like the highest-end mobile i9 Intel had released as of November 2019 when the laptop launched. And the i7-9750H in the base model was also launched in April of that year, and looks like it was their 2nd-fastest mobile hexacore i7 at the time?
