A Raspberry Pi 4 Firmware Update is available providing less heat, same speeds #RaspberryPi4 @Raspberry_Pi @tomshardware

The Raspberry Pi team has announced in their forums the  availability of an update saving power while still keeping the same CPU speeds.

Tom’s Hardware reports the Raspberry Pi Foundation has publicly released the alpha VL805 firmware for general testing, along with a tool capable of querying the current firmware version, saving the existing firmware, and flashing the new firmware.

A firmware update, currently in alpha testing and due for public release as soon as it has been proven it’s not going to crash anything, offers a glimpse at the fruit of the engineers’ labour: tweaks which drop the power draw of the VL805 controller considerably, making the whole Raspberry Pi 4 run cooler.

To test the firmware out, a Raspberry Pi 4 was put on the test bench in two configurations: first running the launch-day firmware as supplied on all retail models and the second running the alpha-test release of the updated VL805 firmware. Both configurations were booted with a single HDMI-connected display, wireless keyboard and mouse dongle in the USB port, and a wired Ethernet connection, to reflect the most common usage, and set running a workload which combined sustained CPU and GPU activity.
