Hardkernel, the maker of Raspberry Pi-like Odroid single-board computers, has released a direct and cheaper rival to the top-end Raspberry Pi 4 4GB model, arguing its new board outperforms the Pi on speed and performance.
The new Amlogic-based Odroid-C4 packs a quad-core Cortex A55 processor with a new-generation Mali-G31 GPU and 4GB of DDR4 memory.
In Hardkernel's CPU tests, the Odroid-C4's Amlogic S905X3 unit outperforms the Raspberry Pi 4 on two of four performance benchmarks and is about equal to it in two other tests.
The Odroid-C4 is not as fast as Hardkernel's Amlogic S922X Odroid-N2, but the N2 is considerably more expensive than the Raspberry Pi 4 and the Odroid-C4.
The Odroid-C4 also outperformed the Raspberry Pi 4's Broadcom VideoCore VI GPU in a GPU performance benchmark and beat it in a memory benchmark.
But the Odroid-C4 doesn't have the same features as the Raspberry Pi 4, so users will need to weigh up what works for their application.
The Odroid-C4 features four USB 3.0 host ports, an RJ45 Gigabit Ethernet port, one HDMI 2.0 display port up to 4K@60Hz, a Micro USB 2.0 port and a power jack.
Notably, unlike the Raspberry Pi 4, it doesn't come with built-in Wi-Fi and Bluetooth. Instead, optional adapters are available for this connectivity. Also, the Raspberry Pi's Broadcom Coretex-A72 runs at 1.5GHz.
The Odroid-C4's eMMC storage connector supports 8GB, 16GB, 32GB, and 64GB and there are green and amber networking LEDs for indicating data traffic at 100Mbps and 1Gbps, respectively.
Two more red and blue system LEDs respectively indicate whether DC power is connected and show kernel activity. There's also a 40-pin expansion header and a seven-pin audio expansion header. The computer measures 85mm x 56mm and weighs 59 grams with the heat sink.
There's an Ubuntu 20.04 LTS 64bit image available with Linux kernel version 4.9.218 LTS. It also supports Google's Flutter UI framework on Ubuntu for building home-automation applications. And there's support for LineageOS, CoreELEC, and Android 9.
