Those of you that have already been putting the new Raspberry Pi 4 through its paces, may have experienced the Pi 4 was throttling its performance during multi-threaded tasks. The Raspberry Pi 4 mini PC is geared to throttle performance at around 80°C to reduce the processor temperature.
But a fix is already in hand and the creator of the Raspberry Pi mini PC Eben Upton has confirmed a firmware update is already under development which is expected to bring the temperature of the bore down by up to 5°C. Upton explains “We’re expecting this to reduce the temperature of the board by 3 to 5 °C in most conditions”. “We expect people who want to run continuous quad-core use cases (benchmarking, big compile jobs) without throttling to require a third-party thermal solution (in the form of decent heatsink or fan)”.,
After carrying out a few tests the TechRepublic website writes “when running sysbench to check 40,000 primes on a 4GB Pi 4, the test completed in 174 seconds using the current firmware and in 170 seconds using the new firmware. An improvement in benchmark performance after installing the new firmware was also found by CNX Software, which also found a reduction in board temperatures of 3°C to 5°C.”
The Raspberry Pi Foundation will this week release a firmware update for the board’s Via Labs VL805 USB controller.
