Editor’s note: This article was updated in February 2019 to include additional Raspberry Pi rivals.

As versatile as the $35 Raspberry Pi is, it is just one of many single-board computers available to buy today.

The Raspberry Pi strikes a fine balance between performance, price, and usability, but leaves plenty of room for other boards to tweak that formula.

In Fall 2018, there was the release of a swathe of new boards, some ramping up the price to add PC-like features — such as support for fast SSD storage and Intel Core processors — while others trim specs to cut costs.

These boards are generally aimed at software developers, hardware hackers, and tech enthusiasts working on projects like home media servers. However, it’s worth pointing out that few boards are as accessible or offer the same breadth of stable software as the Raspberry Pi.

What the La Frite offers

The $15 La Frite comes close to matching the $35 Raspberry Pi 3 B+ in some key respects, using the same underlying Arm-based CPU and even offering faster DDR4 memory.

On paper, the La Frite also promises comparable video playback performance to the Raspberry Pi 3 B+, can output to 1080p displays via HDMI 1.4, and offers two USB 2.0 ports.

As you’d expect there are various cutbacks compared to the Pi and other Raspberry Pi competitors. The board is missing the Raspberry Pi 3 B+’s Wi-Fi support, offers a slightly slower wired Ethernet connection, and has a slightly slower processor.

Specs for the La Frite

  • Quad 64-bit ARM Cortex-A53 CPU Cores at 1.2GHz
  • 2 Geometry + 3 Pixel ARM Mali-450 GPU Cores
  • 512MB or 1GB DDR4 @ 2400MHz
  • 128Mb SPI NOR
  • HDMI 1.4 with 1080P Output
  • 100Mb Fast Ethernet
  • USB 2.0 Host
  • USB 2.0 OTG
  • IR Sensor

What the NanoPi NEO4 offers

The cheapest six-core single-board computer to be released, boasting relatively modern features like USB 3.0 and support for 4K displays.

But there’s a catch, the board may only cost $45, only $10 more than the Raspberry Pi 3 B+, but it only comes with 1GB of memory, has slower Wi-Fi, and fewer Type-A USB ports.

If you can work within limitations of the memory, the board also supports reasonably fast data transfer via its USB 3.0 and Gigabit Ethernet ports, as well as one USB 2.0 Type-C port. Additionally, there’s potential for adding fast SSD storage via a PCIe x2 interface and 4K video out via HDMI 2.0.

What the Odroid-H2 offers

With specs more akin to a low-end PC, the Odroid-H2 costs almost three times the price of the $35 Raspberry Pi 3 B+.

As an x86 Intel Celeron based board, it can run a wider range of Linux-based operating systems than a typical Arm-based, single-board computer.

Its specs stand out from the crowd too, with the ability to add fast SSD storage via its 4 x PCIe 2.0 NMVe interface and SATA 3.0 ports, and support for up to 32GB of DDR4 RAM. Additionally, there is fast network connectivity via the two gigabit Ethernet ports, although no mention of Wi-Fi support. However, while Odroid boards have a good reputation for software support, this board doesn’t appear to be targeting hardware hackers, with only a 20-pin expansion header.

The board’s 2.3GHz Intel J4105 processor — a “Gemini Lake” system-on-a-chip dating from 2017 — is also faster than the Arm Cortex A53 / A72-based CPUs found in recent SBCs.

What the Orange Pi 3 offers

Orange Pi’s latest flagship board boasts specs better than the Raspberry Pi 3 Model B+ for the same price as the $35 computer.

The latest board in the Orange Pi family, the Orange Pi 3, packs a quad-core 1.8GHz CPU, 2GB DDR3 RAM, four USB 3.0 ports, support for 4K displays via HDMI 2.0a, Gigabit Ethernet, onboard mPCIe 2.0, and Bluetooth 5.0.

All of these specs improve on the most powerful Raspberry Pi, the Pi 3 Model B+, and the makers of the Orange Pi 3 suggest their board has a similar range of uses to Raspberry Pi, from desktop computer to media center.

Android 7, Ubuntu, and Debian are listed as officially supported operating systems on the Orange Pi 3 and are available to download here. However, it’s worth noting that historically Orange Pi boards have been criticized for having poor driver support, missing software, and unstable versions of older operating systems.

The Orange Pi 3 also lacks the expandability of the Raspberry Pi, as it only has a 26-pin header for hooking up the machine to other electronics.

The board is built around the same Allwinner H6 SoC as last year’s $20 Orange Pi One Plus, but the Orange Pi 3 adds additional USB ports and memory.

What the Rock Pi 4 offers

The Rock Pi 4 promises a decent balance between price and power. The Rock Pi 4 starts at $39, making it the cheapest single-board computer based on the powerful Rockchip RK3399 system-on-a-chip.

The processor is capable for the price, with a dual-core 2.0GHz Arm Cortex-A72 paired with a quad-core 1.5GHz Arm Cortex-A53, smooth 4K playback is possible with the right media player courtesy of the HDMI 2.0 port and Mali-T864 GPU, fast SSD storage is also an option, via an M.2 interface supporting up to a 2TB NVMe SSD, and the ability to add up to 128GB eMMC storage to the board. The memory is relatively fast — 64-bit, dual-channel 3,200Mb/s LPDDR4 — and ranges from 1GB ($39) to 4GB ($75).

Portwise, there are four USB Type-A ports — one USB 3.0 host, one USB 3.0 OTG, and two USB 2.0 hosts. There’s also a 40-pin expansion header for connecting to other electronics, though this isn’t 100% GPIO compatible with the header on the Raspberry Pi. The $39 Model A lacks wireless connectivity, while the $49 Model B offers 802.11ac Wi-Fi and Bluetooth 5.0.

The board supports more Linux distributions than some Raspberry Pi rivals, including: Android, Android TV, Debian, Ubuntu Server, Armbian 5.67, and retro-games OS Recalbox.

In testing the $75 Rock Pi 4 Model B, TechRepublic found the board comprehensively outperformed the Raspberry Pi 3 Model B+, but also both the Android and Debian images suffered from some instability and jankiness. The Rock Pi 4 Model B also came with a heatsink, so board wouldn’t fit into most Raspberry Pi cases.
