Hardkernel has canceled the launch of the ODROID-N1, the first dev-board with the Exe-core processor Rockchip RK3399, due to some problems with the supply of RAM and decided to replace it with ODROID-N2. Just in recent days, the South Korean company has officially unveiled the new development board that will have a SoC Amlogic S922X “faster and with native support for DDR4 RAM” made with six cores, of which four cores ARM Cortex-A73 from 1.8GHz and two 1.9GHz ARM Cortex-A53 cores with ARM Mali-G53 graphics.
CNX-Software has found the first Amlogic S922X (Geekbench) benchmarks on the web and the results confirm the expectations: the performance of this SoC is much better than those recorded by the Rockchip RK3399 of ODROID-N1 with faster multi-core performance of about 20%, DDR4 RAM more reactive than 35%, Mali-G52MP6 more powerful by about 10%, in addition to a throughput of 340 MB / s for USB 3.0 and over 900 Mbps for Gigabit Ethernet.
The system, which measures 90 x 90 mm, is then completed by 2-4GB of DDR4 RAM at 1320MHz, optional support for an 8GB, 16GB, 32GB, 64GB and 128GB eMMC module expandable with a microSD card slot. Connectivity includes Gigabit Ethernet (RJ-45), HDMI 2.0a with support for video up to 4K @ 60fps, 3.5mm audio jack, AV port (composite video + stereo audio), four USB 3.0 ports, plus a micro USB port 2.0 OTG. There is also a 40-pin expansion header with two I2Cs, UARTs, six PWMs, SPIs, S / PDIFs, two ADCs and GPIOs.
The processor is located at the bottom of the single-board, while the interfaces on the upper face, an interesting solution that allowed the company to install a large metal sink under the board to keep the components “cool”. Optionally, the user can add a fan if he wants an active dissipation system. According to reports from Hardkernel, ODROID-N2 consumes about 1.8 watts if it is inactive, about 5.5W under heavy load and 0.2W when off. The dev-board was also tested in extreme conditions with an ambient temperature of 35 ° and the CPU never exceeded 74 °.
ODROID-N2 will be on sale for $ 63 with 2GB of RAM and $ 79 with 4GB of RAM. Hardkernel will offer ISO images of Android 9.0 Pie and Ubuntu 18.04 LTS, the latter with support for video decoding through hardware acceleration.
