The ability to support multiple displays and high-definition video makes these boards suitable for home theater PC (HTPC) applications.
- Personal Computers While traditional desktop PCs are bulky and require significant power, single board x86 computers offer a compact and efficient alternative. Many people use these boards for low-cost personal computers, as they provide the ability to run full operating systems like Windows 10 or Linux. With proper peripherals, single board x86 computers are perfect for home use or as lightweight workstations.
Comparing Single Board x86 Computers with ARM-Based SBCs
While single board x86 computers offer several advantages, ARM-based SBCs like the Raspberry Pi, BeagleBoard, and others also have their own merits. Let’s compare single board x86 computers with ARM-based SBCs in terms of performance, price, and compatibility.
| Feature | Single Board x86 | ARM-based SBC |
|---|---|---|
| Processor | Intel/AMD x86 CPUs | ARM Cortex-A/R CPUs |
| Performance | High performance | Moderate to high performance |
| RAM | 2GB – 16GB or more | 512MB – 8GB |
| Storage | SSD, microSD, M.2 | microSD, eMMC, USB |
| Operating System | Windows, Linux, others | Linux, Android, Raspbian |
| Expansion Options | PCIe, GPIO, USB | GPIO, USB, HDMI |
| Energy Efficiency | Low to medium power usage | Medium power usage |
| Cost | Higher | Generally lower |
From the comparison above, single board x86 computers typically have more powerful processors and greater memory capacity than their ARM counterparts. They also have more expansive storage options and compatibility with full desktop operating systems. However, ARM-based SBCs tend to be more affordable and energy-efficient, making them ideal for projects that don’t require the full capabilities of x86 systems.
Performance and Benchmarks
In terms of performance, single board x86 computers usually outperform ARM-based SBCs when it comes to running resource-intensive applications, such as high-end media streaming or virtualization. The following table outlines the performance benchmarks for a popular single board x86 and an ARM-based SBC.
| Benchmark | Single Board x86 | Raspberry Pi 4 |
|---|---|---|
| CPU Benchmark | 45,000 (sysbench) | 15,000 (sysbench) |
| Network Throughput | 1Gbps+ | 400 Mbps |
| Storage Speed (SSD) | 500 MB/s | 20 MB/s |
| Power Consumption | 15W | 5W |
As seen in the table, single board x86 systems outperform ARM-based boards in most benchmarks, particularly in CPU performance, network throughput, and storage speed. However, these improvements come at the cost of higher power consumption.
