First on the list is the computer for the Rock64 multimedia board. [больше не доступен] by Pine64. Designed to be a direct competitor to the Pi, this board has several key advantages over the Pi.
The board comes at several prices, reflecting the amount of onboard RAM. For a fair comparison, we will consider the 2 GB version, since according to $34.95 It competes with the Pi 3. At the time of writing, Rock64 has not yet shipped, although its setup looks extremely promising. quad core CPU Rockchip RK3328 with clocked at 1.5GHz ahead of the Pi 3. The Rock64 has twice as much RAM as its Pi counterpart, as well as a socket for adding eMMC boot memory. It comes with the familiar full set of GPIO pins.
Other goodies include a Gigabit Ethernet port, and while the Rock64 has one less USB port, it does have one USB 3.0 port and two USB 2.0 ports. The HDMI output on the Rock64 supports 4K at 60 frames per second (FPS).
This board seems like a no brainer? Well, it’s not without its limitations. It doesn’t have built-in Wi-Fi or Bluetooth support, while the Pi 3 has both. The Rock64 needs to be powered by a +5V 3A jack, and while it’s not that hard, it’s not as convenient as the micro USB cable needed to power the Pi.
2. NanoPi NEO Plus2
Another strong contender from FriendlyArm is the NanoPi NEO Plus2. The quad-core 64-bit Cortex A53 Allwinner H5 can outperform the Pi 3 on paper, though that’s not the main advantage.
This board combines a huge amount of features with a small footprint, half the size of the Raspberry. It also boasts a Gigabit Ethernet port, as well as built-in Wi-Fi and Bluetooth connections. It has 8GB of internal eMMC storage and a MicroSD slot, along with 1GB of DDR3 RAM. All these features are also available at a lower price as the board is available for just $24.99 from the FriendlyArm website.
