NanoPC-T4: A powerful Raspberry Pi alternative without the bottleneck issues

Автор: | 25.05.2018

For users and developers looking for a more powerful alternative to the Raspberry Pi, the NanoPC-T4—FriendlyELEC’s newest single-board computer (SBC)—uses the same system-on-a-chip (SoC) as Samsung’s Chromebook Plus, but at a fraction of the price.

The NanoPC-T4 is a 100x64mm SBC powered by a Rockchip RK3399, which pairs a dual-core 2.0 GHz Cortex-A72 with a quad-core 1.5 GHz Cortex-A53 in a Big.LITTLE configuration, with a Mali-T864 GPU, and 4K VP9 and 10-Bit H.265/H.264 hardware video decoder, with 4 GB RAM and 16 GB storage onboard. It is bundled with a heatsink, radio antennas, a power adapter, and an acrylic case for $119. While this is a sizable increase from the Raspberry Pi’s famed $35 price point, the Pi series is sold as a board only, with third party integrators providing case options and power supplies for an additional fee.

The NanoPC-T4—aside from having a more powerful processor—concentrates on addressing the performance bottlenecks of the Raspberry Pi, making it a compelling choice for professionals. While the Raspberry Pi is limited to only relatively slow microSD storage, the NanoPC-T4 has a 16 GB eMMC onboard, as well as an M.2 2280 connector, allowing for high speed PCIe SSDs to be used. The M.2 connector supports PCI Express 2.1, and is wired for x4, making it possible to get I/O speeds faster than comparable SATA-linked SSDs.

Officially, the NanoPC-T4 supports Android 7.1 and Lubuntu 16.04 with GPU and VPU acceleration. Unofficially, because of how widespread devices with the Rockchip RK3399 are, the SoC has received a great deal of attention in support in the Linux kernel. Mainline support was added in 4.12, with additional fixes provided in subsequent versions, some of which are from open source consultancy Collabora.

While the explosive popularity of the Raspberry Pi has led to a the proliferation of inexpensive single-board computers with more processing power or unique features, the education-minded Raspberry Pi has remained more popular than competitors due to the mainline Linux kernel support, and the ecosystem that developed around the boards. With mainline support for the RK3399 SoC, the NanoPC-T4 may be a more compelling alternative than other boards powered by different SoCs.

Here are the full specs for the NanoPC-T4:
