Apple recently launched its new 14-inch and 16-inch 2021 MacBook Pro models with new Apple Silicon and a major redesign. The new chips offer enhanced performance and battery life on the machines and so far the devices have been pretty well received. In addition, Apple's step to move away from Intel has allowed it to excel in chip manufacturing while beating most of the competition. However, the new 16-inch 2021 MacBook Pro with M1 Max chip features a High Power Mode which allows it to boost performance for intensive workloads.

The references for a High Power Mode in the 16-inch 2021 MacBook Pro with M1 Max chip were discovered in the macOS Monterey beta (via MacRumors). You might already be familiar with Low Power Mode which reduces performance to save battery life. The new High Power Mode is exactly the opposite as it takes more power and in return allows for a major performance boost. However, the new High Power Mode will only be available on the 16-inch 2021 MacBook Pro with an M1 Max chip and not the 14-inch model with an M1 Pro chip.
