Single-board computers (SBCs) have revolutionized the world of embedded systems, offering compact, cost-effective solutions for a wide range of applications. Among the most popular architectures for SBCs is x86, a family of microprocessors developed by Intel and AMD. x86 SBCs combine the power of traditional desktop processors with the flexibility of embedded systems, making them ideal for projects requiring higher computational performance and compatibility with standard PC software.
In this article, we will dive deep into the world of x86 SBCs, discussing their architecture, applications, advantages, and how to choose the right one for your project. Additionally, we will explore some of the top x86 SBCs available on the market, their specifications, and how they stack up against other popular SBC architectures such as ARM.
What are x86 SBCs?
x86 SBCs are single-board computers that use processors from the x86 family. These processors are typically designed for desktop or laptop computers, but in an SBC format, they offer the same processing power in a compact, embedded form. The term “x86” refers to a family of instruction set architectures (ISAs) based on the Intel 8086 microprocessor, which has been extended and improved over the decades.
Compared to ARM-based SBCs, which are more commonly found in low-power applications like Raspberry Pi, x86 SBCs are designed to handle more demanding tasks. These SBCs run standard desktop operating systems like Windows and Linux, which allows for greater flexibility in software development.
Key Features of x86 SBCs:
- Compatibility with x86 Software: One of the biggest advantages of x86 SBCs is their ability to run a full desktop operating system, such as Windows or Linux, and support a wide range of software designed for x86 architecture.
- Higher Performance: x86 processors generally offer higher processing power than ARM processors, making them suitable for more demanding tasks such as digital signage, media centers, and edge computing applications.
- Expandability: Many x86 SBCs come with expansion slots or support for additional peripherals, offering greater flexibility in terms of connecting external devices and components.
- Cost: While x86 SBCs are generally more expensive than ARM-based boards, they provide greater performance and software compatibility, making them a worthwhile investment for more demanding applications.
Why Choose an x86 SBC for Your Project?
Choosing the right SBC for your project depends on several factors, including processing power, compatibility, power consumption, and cost. x86 SBCs stand out for their ability to run mainstream operating systems and software without requiring specialized development environments. Below are some reasons why you might consider using an x86 SBC:
- Familiarity with PC Software: Since x86 SBCs can run standard desktop operating systems like Windows and Linux, developers familiar with traditional PCs can easily transition to building embedded systems without having to learn new software or architectures.
- Performance: x86 SBCs offer significant computational power, which makes them suitable for tasks such as media streaming, gaming, or heavy computing workloads. ARM SBCs, while efficient, typically don’t match the performance of modern x86 chips.
- Wider Software Ecosystem: The x86 architecture has been around for decades and has a massive software ecosystem. From office applications to specialized industry software, x86 SBCs can run the same programs that are used on PCs.
- Compatibility with Peripherals: x86 SBCs generally support more robust connectivity options, such as PCIe slots, SATA interfaces, and multiple USB ports, enabling more complex integrations with peripheral devices.

How to Choose the Right x86 SBC for Your Project
When selecting an x86 SBC, you need to consider the specific requirements of your project. Here are some key factors to keep in mind:
- Performance Needs:
- For projects that require high performance, such as media servers or gaming, opt for SBCs with more powerful processors like the Intel Core m3 or Intel Core i7.
- If your project is lightweight or focused on basic tasks like data collection or IoT applications, an Intel Atom processor may be sufficient.
- Connectivity:
- Evaluate the available connectivity options, including USB ports, HDMI, Ethernet, and Wi-Fi. Some SBCs offer multiple USB 3.0 ports and high-speed Ethernet, which are useful for applications that involve data transfer.
- Operating System Compatibility:
- Ensure that the SBC you choose is compatible with the operating system you plan to use. Most x86 SBCs support popular Linux distributions and Windows, but check for compatibility with your specific software stack.
- Size and Form Factor:
- Consider the size of the SBC. Some projects require a compact form factor, while others may have space for larger boards with more expansion options.
Challenges of Using x86 SBCs
While x86 SBCs offer many advantages, there are also some challenges that need to be considered:
- Power Consumption:
- x86 processors generally consume more power than ARM processors, which can be a concern for battery-powered or low-power applications.
- Cost:
- x86 SBCs tend to be more expensive than their ARM counterparts. This could be a significant factor when developing cost-sensitive projects.
- Software Complexity:
- Although x86 SBCs are compatible with desktop operating systems, configuring and optimizing software can be more complex compared to using lightweight Linux distributions designed for embedded systems.
