The world of inexpensive SBCs or single board computers has been taken by a storm with the unveiling of the new Raspberry Pi board or the RBPi 3. The claim being it blows the competition away, and that no one can match its price. However, that may not be entirely true, as the Odroid C2 SBC seems to best the RBPi 3.
Hardkernel promotes its Odroid C2 as another cheap and speedy SBC with a 64-bit ARM-based quad core processor. A comparison of the specifications shows the C2 may be giving the RBPi 3 a run for its money. Compare for instance, the BCM2837 of the RBPi 3 with the Amlogic S905 SoC of the C2. Although both are quad-core ARM Cortex-A53, the C2’s processor runs at 2GHz to the 1.2GHz of the RBPi 3. At 2GB, the C2 has double the RAM of the RBPi 3, which has only 1GB. Moreover, the C2 comes with a Mali-450 GPU, able to deliver 4K video.
Although the C2 does not have the on-board wireless and Bluetooth features of the RBPi 3, it has a high-speed Gigabit Ethernet port directly wired into the SoC. The RBPi 3 also has Ethernet on-board, but as this is a 100-megabit port and is on a USB interface, its speed is likely to be limited.
The two boards share a very similar form factor and are nearly identical in their GPIO capabilities. In addition, for both the boards, you can choose the storage to be either the usual micro SD card or eMMC. However, it is worth stating that the C2 comes with a built-in ADC or analog to digital converter. When it comes to operating systems, the C2 can operate with Ubuntu 16.04, or Android lollipop.
The RBPi family, just like Apple products, has always faced competition. However, most look good only on paper, but their prices always let them down in the end, and we never hear of them after some time. The price of $40 for the C2, being very close to that of the RBPi 3, may just escape this fate. Of course, there is the matter of adding shipping and customs to the price, as the origin of C2 is Korea.
So, which of them is preferable – the C2, or the RBPi 3 – and why? The faster processor of the C2 and its faster wired networking would make it attractive to someone working on network-attached data processing applications. Although one can add a USB wireless network adapter for only a few dollars, the onboard Wi-Fi and Bluetooth of the RBPi 3 makes it so much more attractive. Therefore, the RBPi 3 would be coveted by anyone who is a home user or planning to use a computer on a platform that will remain unfettered by wires.
Although the C2 may be more impressive when compared to the RBPi 3, the latter will likely outsell the C2 many times over. This may not be because of the massive publicity advantage that the RBPi 3 is receiving from the Pi foundation, but more likely due to the wide ecosystem of hardware and software developers the RBPi family has at present.
