STM32G4 Performance at 1.8V

Would STM32G4 performance gets effected if runs at lower voltage (1.8V)? Can the core clock run at max 170MHZ or it will run lower speed?

The max clock speed of some things will be lower at 1.8 V than at 3.3 V. For example, the max SPI speed is lower. You can see this in the datasheet.

However, the core clock can still run at 170 MHz at 1.8 V. No loss in performance there.
