For most Linux single-board computer buyers, Arm is the safer choice. It offers the broadest selection of tested images, drivers, accessories and board-specific documentation. Choose RISC-V when an open instruction-set architecture, processor experimentation or participation in a newer ecosystem matters more than the least-friction setup. The decisive comparison is not the ISA alone: it is the complete board, SoC, firmware, kernel, drivers and distribution image.
The short answer
Arm currently wins on general-purpose Linux practicality, while RISC-V wins on architectural openness and experimentation. Both can run serious Linux software, and Debian 13 now officially supports the 64-bit riscv64 architecture as well as established Arm architectures. That distribution-level support is an important milestone, but it does not make every RISC-V board equivalent to a mature Arm board.
| Choose Arm if you need | Choose RISC-V if you need |
|---|---|
| A predictable first boot and a large library of board guides | An open ISA whose specifications are publicly available |
| Broad peripheral, camera, GPU and multimedia support | Hardware experimentation, custom processor work or research |
| Many cases, expansion boards and accessories | Willingness to check board-specific images and drivers carefully |
| A production-like classroom, desktop, robotics or embedded project | To help explore a younger, fast-growing Linux ecosystem |
If your project has a hard requirement for a particular GPU feature, camera stack, wireless chipset, suspend mode or hardware codec, select the board that documents that feature—not simply the board carrying your preferred ISA.

Why the architecture label is not enough
ISA, CPU core and SoC are different layers
An instruction-set architecture (ISA) defines the instructions software can use and the rules an implementation follows. Arm and RISC-V are ISAs; a single-board computer is a much larger system. Its system-on-chip (SoC) combines CPU cores with graphics, memory controllers, media engines, USB, storage interfaces, display outputs and other blocks. Firmware, a bootloader, the Linux kernel and device drivers must bring those blocks up correctly.
#1 Best Overall
- Raspberry Pi 5 with 8GB RAM: Model SC1112 featuring a quad-core ARM Cortex-A76 processor running at 2.4GHz. Enhanced Connectivity: Includes dual 4K micro HDMI ports, USB-C power input, and high-speed USB 3.0 ports. PCIe Expansion Support: FPC connector enables M.2 NVMe SSDs when using compatible adapters. Fast Storage Options: Works with microSD cards for booting, or optional NVMe storage for advanced projects. Built for Projects & Learning: Ideal for programming, home labs, DIY electronics, automation, and Linux-based development.
Two boards using the same ISA can therefore have very different Linux experiences. A vendor may provide a working image for one SoC while another board using the same architecture has incomplete graphics acceleration or no supported camera driver. Conversely, software that runs on one Arm board may need a different kernel configuration or firmware package on another.
The complete software stack determines usability
For an SBC, evaluate these layers together:
- Boot firmware and bootloader: Can the board reliably start the advertised distribution from its intended storage?
- Kernel support: Are the board’s devices supported by an upstream or actively maintained kernel, and which kernel version does the image use?
- Device drivers: Do Wi-Fi, Bluetooth, USB, Ethernet, cameras, displays, audio and sensors work without vendor-only patches?
- Acceleration: Is the GPU usable for a desktop, and are video encode/decode paths available for the workloads you care about?
- Distribution image: Is there a maintained image for your exact board revision, not merely for the architecture in general?
- Maintenance: How are security updates, kernel updates and bootloader fixes delivered?
Linux distribution support in 2025 and beyond
Debian 13 makes riscv64 an official architecture
Debian 13 is the first official Debian release for 64-bit RISC-V. The Debian Project describes the release as the first time users can run Debian on 64-bit RISC-V hardware and receive the Debian 13 feature set through an official architecture port. Debian 13 also officially supports Arm’s 64-bit arm64 architecture.
That milestone means package availability and build infrastructure are no longer purely experimental at the distribution level. It does not certify every board. Debian’s own documentation notes that riscv64 has had less user exposure and testing than established architectures, so bugs and board-specific gaps are more likely. A board can be capable of running Debian while still lacking a polished installer, accelerated graphics, a working wireless driver or a reliable suspend path.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsUbuntu and other distributions remain board-specific
Ubuntu publishes support information for selected Raspberry Pi and RISC-V boards. Treat those lists as board-and-image compatibility information, not as a blanket promise that every device using Arm or RISC-V will work. Check the exact model, memory variant and image release before downloading.
Architecture packages are only the foundation. The practical question is whether the distribution image includes the firmware, device-tree files, kernel configuration and boot files required by your particular board.
What Arm offers Linux SBC buyers
A mature ecosystem
Arm has been used in single-board computers for many years, giving developers a large body of board-specific documentation and community knowledge. That maturity commonly shows up in ready-made operating-system images, installation guides, cases, expansion boards, tutorials and troubleshooting discussions. It also gives vendors and upstream projects more time to stabilize drivers for common peripherals.

- Includes 128GB Micro SD Card pre-loaded with 64-bit Raspberry Pi OS, USB MicroSD Card Reader
- CanaKit Turbine Black Case for the Raspberry Pi 5
- CanaKit Low Noise Bearing System Fan
- Mega Heat Sink - Black Anodized
Maturity is not uniform: an inexpensive or newly released Arm board can still have weak documentation or vendor-only drivers. Nevertheless, the probability of finding an existing solution is generally higher than with a comparable new RISC-V board.
Raspberry Pi 5 as a mainstream reference point
The official Raspberry Pi catalog describes Raspberry Pi 5 as a Linux-capable board built around a Broadcom BCM2712 and a 2.4 GHz quad-core 64-bit Cortex-A76 processor. It is a useful Arm baseline because it combines a mainstream 64-bit CPU with the usual single-board-computer interfaces and a full Linux operating-system ecosystem.
Use that specification as a reference, not as a guarantee that every Arm board performs identically. CPU frequency alone does not describe storage speed, graphics performance, thermal behavior, USB bandwidth or the quality of a board’s firmware and drivers.
What RISC-V offers Linux SBC buyers
An open, published ISA
RISC-V International states that the RISC-V open-standard ISA defines the fundamental guidelines for designing and implementing RISC-V processors, and that its ratified ISA specifications are free and publicly available. This openness allows organizations to design compatible processors without licensing the ISA in the same way as a proprietary instruction-set specification.
For developers, that can make it easier to study the instruction set, build custom extensions, teach processor design and investigate specialized hardware. It does not automatically make a board cheaper, faster or better supported. Implementation quality, memory bandwidth, accelerators, firmware and software still determine the user experience.

RISC-V International’s developer-board listing for the Orange Pi RV2 8GB identifies up to 8 GB of LPDDR4 memory, optional eMMC storage, Wi-Fi 5, Bluetooth 5 and a 2 TOPS AI accelerator. Those specifications make it interesting for experimentation and edge workloads.

Before treating it as a direct replacement for a mainstream Arm SBC, verify the exact vendor image, kernel version, graphics acceleration, video support and peripheral behavior for your intended workload. A headline accelerator figure does not establish that a Linux framework or application can use the accelerator, and wireless specifications do not by themselves prove that the supplied driver is stable across kernel updates.
Arm and RISC-V compared for Linux SBC projects
| Criterion | Arm SBCs | RISC-V SBCs |
|---|---|---|
| Distribution availability | Mature arm64 and armhf images with long-established board guides | Debian riscv64 is official in Debian 13; individual board images vary considerably |
| Driver and multimedia coverage | Generally broader vendor and community coverage | Highly dependent on the SoC, firmware and upstream-kernel status |
| Accessories and documentation | Large catalog of cases, expansion boards, tutorials and accessories | Smaller but growing catalog, with more variation between boards |
| ISA licensing model | Implementations use Arm’s licensed architecture and implementation ecosystem | Ratified ISA specifications are open and publicly available |
| Best fit | Production-like projects, education, desktop use, media and robotics | ISA experimentation, research, custom hardware and early adoption |
| Primary risk | Assuming a popular brand guarantees support for every add-on or image | Assuming official architecture support guarantees complete board integration |
How to choose a board methodically
Use this sequence before buying or committing software. It prevents the ISA label from hiding a missing driver or an unsupported boot path.
- Write down the workload. Separate server tasks, desktop applications, media playback, camera capture, GPIO control, robotics, AI inference and kernel or hardware development. Each may require a different accelerator or peripheral.
- Identify non-negotiable peripherals. List the exact camera, display interface, wireless standard, storage device, sensors, USB equipment and expansion boards. Search the board’s documentation for those exact devices and the supported Linux release.
- Confirm the image for the exact model. Check the board name, RAM variant and revision. An image for a similarly named board may have a different device tree, bootloader or kernel configuration.
- Check boot and kernel status. Look for documented boot media, firmware requirements and the kernel version supplied. Prefer support that is maintained in the normal distribution or upstream kernel where possible; treat a one-off vendor image as a maintenance dependency.
- Verify graphics and video. For a desktop, inspect whether the GPU has a working Linux driver and whether your display resolution is supported. For media work, confirm hardware decode and encode support in the applications you intend to run.
- Verify wireless and suspend behavior. Confirm that Wi-Fi and Bluetooth work with the intended kernel and that suspend, wake and power management are documented if the device will run from a battery or unattended location.
- Review storage options. Compare the board’s boot media, eMMC or other storage interfaces, and determine whether the operating system supports reliable updates and recovery from a failed boot.
- Assess maintenance evidence. Look for release notes, security-update instructions, issue tracking and a stated update policy. A board with excellent launch-day specifications can become difficult to maintain if images stop being rebuilt.
- Budget for thermals and power. Check whether the board needs active cooling, what power supply is specified and how its consumption fits your enclosure or battery. Do not infer power draw from the ISA.
- Only then compare CPU specifications. Core count, frequency and accelerator figures matter after the software stack meets your requirements.
Practical setup checks after purchase
Run these checks before building the final project. They catch an image mismatch while returning the board is still possible.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →- Install the image recommended for the exact board and record its release and kernel version.
- Confirm the architecture with
uname -m. A 64-bit Arm installation normally reportsaarch64; a 64-bit RISC-V installation reportsriscv64. The command identifies the running user space, not whether every board peripheral is supported. - Read
/etc/os-releaseand note the distribution release. This prevents accidentally mixing packages intended for another board image or release. - Test wired networking, Wi-Fi and Bluetooth separately. Record whether each device appears without installing an unmaintained driver bundle.
- Attach the intended display and test the target resolution, desktop session and hardware-accelerated applications. A screen that works in a basic framebuffer mode is not proof of GPU acceleration.
- Exercise storage, USB devices, cameras, audio and GPIO using the exact libraries your application will use.
- Reboot repeatedly, test a cold boot and, if required, test suspend and wake. Intermittent boot or resume failures are difficult to diagnose after deployment.
- Apply the documented security and kernel updates, then repeat the peripheral tests. An update policy that breaks a critical driver is a project risk even if the original image worked.
Which architecture fits common projects?
General-purpose Linux, learning and classroom use
Choose a well-supported Arm board when students or makers need to spend their time learning Linux, Python, networking or electronics rather than repairing an image. The larger collection of guides and accessories reduces setup variance between learners.
Desktop and media center use
Arm is usually the lower-risk option because graphics and media support have had more time to mature across popular boards. Confirm the actual GPU driver and codec path for the model you select; an Arm label alone is not enough.
Robotics and automation
Either architecture can work if the required GPIO, camera, USB and real-time interfaces are supported. Favor the board with tested drivers and a maintained image for your sensors and motor controllers. A theoretically faster CPU cannot compensate for an unavailable camera or unstable USB stack.

AI and edge inference
Compare the software support for the accelerator, not just its advertised arithmetic number. The Orange Pi RV2 8GB listing’s 2 TOPS figure is potentially useful, but you must establish that your Linux framework, model format and kernel driver can access it.

Processor research and custom hardware
RISC-V is the natural candidate when the ability to inspect and extend the ISA is central to the project. Its open specifications support teaching, simulation, custom implementations and experimentation. Plan extra time for board-specific Linux integration and debugging.
Long-lived or commercial deployments
Select the board with the clearest supply, update and driver-maintenance story. Architecture openness can be valuable, but a deployment also needs reproducible images, security fixes, recovery procedures and stable peripheral behavior. Document the exact board revision and software versions so replacements can be tested consistently.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Common mistakes and how to avoid them
“Official architecture support means my board is supported”
It does not. Debian 13’s official riscv64 status covers the architecture and release process; it does not certify every RISC-V SoC, bootloader or peripheral. Use the board’s own image and hardware support documentation.
“Open ISA means lower cost”
RISC-V’s specifications are publicly available, but board price also reflects memory, storage, manufacturing volume, support and included peripherals. Openness is a design and licensing characteristic, not a guaranteed retail discount.
“The specification sheet proves performance”
Clock speed, core count and TOPS figures do not describe application performance without workload, memory and software context. A missing driver can reduce a nominally powerful accelerator to an unused component.

“A basic display proves graphics acceleration”
Linux can display a desktop through a basic framebuffer while leaving the GPU unused. Confirm acceleration inside the applications that matter to you and check video decode or encode separately.
“A community image is a permanent support plan”
Community images can be excellent, but determine who rebuilds them, how security fixes arrive and what happens when the kernel changes. Keep a known-good image and a recovery method before updating a deployed system.
A decision framework
| Your priority | More suitable starting point | Reason |
|---|---|---|
| Fastest path to a working Linux project | Arm | More mature images, guides, drivers and accessories are available across the ecosystem. |
| Open ISA study or custom CPU work | RISC-V | The ratified ISA specifications are free and publicly available for study and implementation. |
| Camera, desktop GPU or media playback | Usually Arm | Coverage is generally broader, but verify the exact board’s driver and codec support. |
| Experimental board with a specific accelerator | Either | Choose based on framework and driver support for that accelerator, not its label. |
| Unattended deployment with strict update requirements | Whichever board documents maintenance best | Update, recovery and peripheral stability outweigh ISA preference. |
Frequently asked practical questions
Is RISC-V ready for Linux?
Yes, at the distribution level: Debian 13 is the first official Debian release for 64-bit RISC-V, and selected distributions publish images for RISC-V boards. Readiness remains board-specific, especially for graphics, wireless, multimedia, boot firmware and suspend.
Can I run Debian on a RISC-V SBC?
Yes, when the board has a compatible riscv64 image and boot support. Confirm the exact model and image instructions; an official Debian architecture port does not replace the board vendor’s firmware and device-tree requirements.
Can I run Ubuntu on a RISC-V SBC?
Ubuntu supports selected RISC-V boards and publishes board-specific information. Check that your exact board and release are listed before assuming an image will boot or provide complete peripheral support.
Is Raspberry Pi’s Arm architecture better than RISC-V?
For a low-risk general-purpose Linux project, a mature Arm board such as Raspberry Pi 5 is usually the safer choice. RISC-V is better when ISA openness and experimentation are primary requirements.
What should I compare first when looking for a Raspberry Pi alternative?
Compare the complete software and hardware integration: supported image, bootloader, kernel, GPU and video drivers, wireless, storage, community documentation, update policy, price and power requirements. Compare CPU architecture only after those checks.
