Raspberry Pi 4 Benchmarks – Heatsink Edition

A few days ago, I ran some benchmarks in Raspberry Pi 4, and quickly found out that using the board without a cooling solution will cause serious performance issues, as in some cases my board was slower than Raspberry Pi 3 model B due to severe overheating. After playing with LibreELEC yesterday, I’ve now reinstalled Raspbian Buster Desktop on the board, and fitted it with a largish heatsink and some old thermal paste. So I’ll run benchmarks again with and without heatsink. I’ll only run sbc-bench this time. SBC Bench Installation Open a terminal windows or connect to the board through SSH and run:

wget https://raw.githubusercontent.com/ThomasKaiser/sbc-bench/master/sbc-bench.sh

1	wget https://raw.githubusercontent.com/ThomasKaiser/sbc-bench/master/sbc-bench.sh

Raspbian Buster will automatically fetch the latest operating systems packages upon first boot, but apparently not the latest firmware:

/opt/vc/bin/vcgencmd version

version 407b1da8fa3d1a7108cb1d250f5064a3420d2b7d (clean) (release) (start)

/opt/vc/bin/vcgencmd version

version 407b1da8fa3d1a7108cb1d250f5064a3420d2b7d (clean) (release) (start)

So I ran rpi-update to get the very latest firmware as well, and rebooted the board:

/opt/vc/bin/vcgencmd version
Jun 26 2019 17:42:42 
Copyright (c) 2012 Broadcom
version 1186f932808ed601ddd583a30a3ce055477b1a26 (clean) (release) (start)

Normally, you should not have to do it, […]

NanoPi M4 RK3399 SBC Price Drops to $50 and Up

The launch of Raspberry Pi 4 SBC has generated lots of interest, especially with the extra performance and low $35 price tag that has made most alternatives suddenly less interesting. However, Raspberry Pi 4 benchmarks show it’s not quite the fastest board around, and for example, Rockchip RK3399 platforms are still quite faster, sometimes as much as twice as fast. They do cost much more though, often more than twice, and so far one of the cheapest RK3399 boards was NanoPi M4 going for $65. FriendlyELEC has now decided, certainly in response to Raspberry Pi 4 offering, to lower the price to $50 for the 2GB RAM version which compares to $45 with Raspberry Pi 4 2GB, as well as $75 for the 4GB RAM version (was $95). NanoPi M4 specifications: SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 2.0GHz, 4x Cortex-A53 @ up […]

MediaTek Helio P65 Octa-core Processor Combines Cortex-A75/A55 Cores with Arm Mali-G52 GPU

MediaTek Helio P65 is a mainstream’s octa-core processor with two Arm Cortex-A75 clocked at up to 2.0 GHz and six Cortex-A55 cores combined with an Arm Mali-G52 2EEMC2 GPU. What does 2EEMC2 mean you may ask? Well, I have absolutely no idea either, and MediaTek did not bother expanding on the subject. Nevertheless, Helio P65 is said to deliver 25% performance improvement over “competitor alternatives that use older generation cores”, and twice the AI performance over previous generation mainstream Helio series, and up to 30% faster performance versus direct competitor SoCs in AI-camera tasks such as object recognition (Google Lens). The processor also implements VoW (Voice on Wakeup) capability which the company claims “optimizes platform size and power use”, and separates the audio channels for voice commands and calls from media and games in order to deliver better audio quality. MediaTek Helio P65 specifications: Processor – 6x Arm Cortex-A55, 2x […]

4K Video Playback on Raspberry Pi 4 with LibreELEC (Alpha)

In my short Raspberry Pi 4 review, I tested 4K video output and playback in Raspbian, and sadly neither are working properly, with video output stuck to 1080p60 even after selecting 4K HDMI in the settings and yes, I double checked for “hdmi_enable_4k=1” in config.txt, while H.265 video playback is still clearly using software decode in both VLC and omxplayer. However, LibreELEC team announced support for Raspberry Pi 4 in LibreELEC 9.2 Alpha1 release based on Kodi 18.3 and Linux 4.19.x. So I downloaded LibreELEC-RPi4.arm-9.1.001.img.gz and flash it to a microSD card with balenaEtcher. The good news is that I could manually set the resolution to 3840×2160 and confirm it works with my TV, but the refresh is limited to 30 Hz maximum. Other refresh rates currently available include 23.98 Hz, 24 Hz, 25 Hz, and 29.97 Hz. The hardware is capable if 4K 60Hz, so it’s just a question […]
