ODROID C4 ODROID C4 40 GB 4 x 20 GHz
ODROID-C4 is a new generation single-board computer that is more energy efficient and powerful than ODROID-C2, which was presented more than four years ago as the world's first affordable ARM 64bit computer.The main CPU of the ODROID-C4 consists of a quad-core Cortex-A55 cluster with a new generation Mali G31 GPU. The A55 cores run at 2.0GHz without thermal throttling using the standard heat sink, which was designed to provide a rugged and quiet computer. The CPU multicore performance is about 40% faster and the DRAM performance of the system is 50% faster than the ODROID-C2.GPU performanceThe Mali-G31 runs with 650MHz and is ~50% faster than the Mali-450MP in the ODROID-C2. The Mali-G31 is the first generation of Bifrost-based mainstream GPU from Arm.RAM performanceODROID-C4 DDR4 RAM runs with 1320Mhz. The memory bandwidth is 1.6 times higher than the ODROID-C2.EMMC memory performanceThe sequential read and write speed is over 165 MB/s and 125 MB/s.Micro-SD UHS powerWith properly implemented dynamic UHS voltage scaling, sequential read and write speeds are greater than 70 MB/s or 50 MB/s.CryptographyThe ARMv8 architecture supports hardware-accelerated encryption extensions for building a secure system. As expected, ODROID-C4 has enabled us to determine a very decent OpenSSL performance.GPIO (40Pin header)The GPIO interface of the ODROID-C4 is similar to that of the C2 and supports a 3.3V interface. This is useful for using different peripherals without complicated level shifter, as with the XU4's 1.8V GPIOs. Another major improvement is the faster SPI bus interface with a maximum frequency of about 100MHz. This is much faster than the ODROID-C2's 400kHz software bit-banged SPI.Power consumption:Thanks to the modern 12Nm manufactured S905X3-CPU the power consumption and the heat output are relatively low.This text is machine translated.
