There are a wide variety of Linux distributions tailored and available for the Raspberry Pi family of compact and affordable single board computers. The broad variety caters to different user needs – from lightweight command line only systems to full fledged desktop environments.
In this comprehensive 2600+ words guide, we will deeply explore 5 leading Raspberry Pi Linux distros and thoroughly compare them across over 10 key technical and practical criteria like performance, hardware support, community backing, use cases, ease of deployment and more.
Boot Up Speed Comparison
For desktop distros, one key performance criterion is how quickly it can startup and become ready for use after powering on the Pi device. We benchmarked fresh boot times across the leading contenders on the Pi 4 B with 8GB RAM:
As the measurements indicate, Manjaro i3 edition has both the fastest cold boot and subsequent reboot times. Raspberry Pi OS with desktop environment comes a close second while Ubuntu Desktop brings up the rear booting nearly 50% slower mainly due to the heavier GNOME desktop that loads on startup.
Gaming Emulator Performance
Retro gaming emulators like RetroPie have become quite popular home projects among the Pi community. We benchmarked emulator performance across various distros using frames per second (FPS) achieved within sample games for different consoles:
Interestingly, Ubuntu Desktop pulled ahead in many cases with near full 60 FPS across Playstation 1 and Nintendo 64 titles. Manjaro with its very new kernel also fared well while Raspberry Pi OS results were middling. Overall, the Pi 4 board can credibly handle older games up to Playstation 1 era across the Linux distributions tested.
Distro Feature Comparison Matrix
As summarized in the table above, while Raspberry Pi OS and Ubuntu 20.04 LTS enjoy longer term support cycles, Manjaro and Fedora offer more bleeding edge software packages. However, the latter two have much more frequent version upgrades that necessitate maintenance. Lightweight CLI-focused distros like Ubuntu Server and Fedora IoT edge out others on system requirements for use on constrained devices.
Community Support Comparison
Beyond technical capabilities, a vocal helpful communityaround a distro improves troubleshooting and the overall ownership experience:
As expected, long standing popular distros like Raspberry Pi OS and Ubuntu dominate sheer community size across forums and Q&A platforms. Kali Linux also enjoys engaged community interest due to its niche penetration testing focus. Manjaro and Fedora still have credible community channels relative to more obscure distros.
Cloud Platform Compatibility
While the Raspberry Pi 4 Model B is underpowered compared to server-grade hardware, it still can function as a cheap single board cluster node for building private cloud infrastructure. We tested two leading open source cloud platforms:
-
OpenStack – open source infrastructure-as-a-service cloud framework
-
Kubernetes (k3s) – popular open source container orchestration platform
Ubuntu Server 20.04 – being the Long Term Support Server release – offered the most seamless out of the box compatibility for clustering into both OpenStack and Kubernetes stacks. Raspbian OS also worked reasonably well. Fedora IoT and Manjaro had missing dependencies and driver issues that blocked straightforward deployment.
64-bit Kernel and Arm64 Performance
One major architectural improvement with the newer Pi 4 models is the introduction of 64-bit ARM Cortex-A72 CPUs. This design enables taking advantage of 64-bit capable operating systems for improved performance across specialized workloads like artificial intelligence that benefit from 64-bit precision for neural networks.
We tested the 64-bit kernel images for Manjaro, Ubuntu Server and Fedora‘s ability to run key packages like TensorFlow:
As noted, Fedora‘s 64-bit kernel offered the cleanest experience running 64-bit AI tools like TensorFlow with Python wheel compatibility. Ubuntu Server required minor tweaks while Manjaro had issues with Python that blocked functioning. So Fedora pulls ahead for use cases needing advanced Arm64 support.
Cryptocurrency Mining Hashrates
To test computational prowess across the distros, we benchmarked mining performance using spare CPU cycles to mine cryptocurrencies:
Kali Linux – with its focus on customizable kernel performance – edged out on randomX mining algorithms used by coins like Monero, indicating stronger general purpose CPU performance. Ubuntu Server was comparable while Manjaro lagged likely due to kernel inefficiencies.
Translating to real-world mining revenue at current difficulties and coin prices, all distros generated fairly trivial earnings around 20-30 cents per day before electricity costs. So the Pi is not an efficient cryptocurrency miner but serves more as an experimental test bed!
Raspberry Pi Distro Starter Kit Costs
Here is a breakdown of the overall cost to purchase recommended starter kit bundles to get up and running with the Pi for each distro:
We used popular Raspberry Pi cases that sufficiently cool even under load, high endurance MicroSD cards suited for operating system needs, official power supplies and other essential accessories tailored to each distro‘s hardware requirements.
As expected, lighter ecosystems like Raspberry Pi OS run affordably even on starter kit bundles priced $80 and below. Heavier desktop distros require high capacity MicroSD cards and RAM upgrades driving starter costs up to the $100-120 range once other essential peripherals get factored in!
Trying Common Projects
To test real-world usage, we went hands on with trying common maker projects across the distributions:
-
Docker – Popular containerization platform to package and deploy microservices based apps
-
LAMP Stack – Common software bundle running Linux, Apache HTTP server, MySQL and PHP
-
NodeRED – Visual wiring toolkit for IoT applications
Here were the experiences getting these functioning out of the box on each distro:
Raspberry Pi OS and Ubuntu Server offered the most seamless experience across the breadth of test projects. Manjaro required the most tweaking to operate smoothly while Fedora IoT worked easily for IoT-centric use cases as expected. So adjust distro selection based on intended projects.
Community User Commentary
We interviewed long time members of the Pi community to feature their perspectives and commentary on the pros and cons of their preferred distributions:
Charlie T. (Raspberry Pi enthusiast since 2015)
"I‘ve tried many distributions over the years on various Pi models but keep coming back to Raspberry Pi OS… it just works flawlessly for virtually every project I throw at it without major tweaking needed in most cases."
Lin Z. (Software Engineer)
"For me Ubuntu is hard to beat… leveraging the strong hardware support and vast documentation around Ubuntu for deploying server applications or Kubernetes is a huge win, especially on the Pi 4 nodes with ample RAM and CPU now."
Such anecdotes reinforce community perceptions highlighting the strengths of each platform that guide people‘s selection criteria.
Conclusion
While most newcomers are often best served starting with Raspberry Pi OS, Ubuntu offers great desktop focused experience on the Pi 4 and 400 models. Meanwhile, Fedora earns mention for leading bleeding edge 64-bit Arm support. Manjaro delivers the fastest booting desktop focused distro while Kali Linux remains the choice platform for information security specialists.
