Teensy 4.0 is pretty much a Teensy 3.2 with 13X greater performance, as it features a 600MHz ARM M7 processor!
Featuring the (presently) fastest microcontroller on the market, Teensy 4.1 more than quadruples the performance of the Teensy 3.6, and more than 6x faster than an ESP32, and still is Arduino IDE-compatible! In comparison to the Teensy 4.0, the 4.1 breaks out more peripherals and adds an easy to use USB header.
As usual, PJRC has broken out a great many features to this chipset:
Power consumption is also very manageable, being about 100mA in normal operation. Additionally, it supports dynamic clock scaling while maintaining proper timing across the peripherals. Serial and sampling rates work properly as you scale the CPU speed.
