Raspberry Pi 4 Tests (Pt.1) - Beta Firmware Reduces Heat!

In this video I test the electrical and thermal changes due to the beta firmware for the Raspberry Pi 4's USB3 Controller which was released recently. This is part 1 of a multi-part series on the Raspberry Pi 4. More in-depth testing will be done in this video series for the Pi4 and comparison testing with the Pi3. Leave a comment for what you'd like to see!

The beta firmware reduces power consumption of the Pi 4 between 8% to 12% in the testing shown in this video. It also reduces the heat generated in total by the Pi 4 which adds around 25% more full CPU load time before it starts to thermal throttle. I don't recommend installing this firmware unless you are comfortable testing buggy beta firmware.

You can also see in the video that the power utilization increases as the temperature of the Pi4's CPU (and board) increases. I will discuss this in the next video when I compare the Pi4 to the Pi3.

Beta firmware for the USB3 Controller can be found here: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=243500&p=1490467&hilit=firmware#p1490467

Everything seen and used in the video was bought with my own money. Looking forward to making a full review video for the EEVblog 121GW Multimeter.
