See Table 3-5 Operating Conditions on page 162 of the datasheet: the maximum frequency for all 3 CPUs is 200 MHz.

Can I assume the core 1 is warmer than core 0 but can be ignored? Because the core max frequency is limited by PLL, so the 200MHz is quite below the design limitation of the 1.6P, which is for 300MHz.
Thanks,

The synthesis is different between the TC29x (300 MHz maximum) and the TC27x (200 MHz maximum). The numbers in Operating Conditions are not just guidelines - they are actual maximum ratings.
The PLL for both TC29x and TC27x is 400 MHz min / 800 MHz max, so that's not where the limitation comes from.
