Dear Radxa community:
We noticed there are some discussions and dissatisfaction about the specification change of the O6 on the Radxa website.
Both Radxa and Cix teams are closely monitoring community discussions, and engineers from Cix have joined the Radxa forum to actively support users. We have regular bi-weekly open-source status meetings between Radxa and Cix, specifically addressing community-reported issues and continuously improving both hardware and software experiences.
Regarding the DRAM bandwidth (100GB/s) :
Currently, the DRAM runs at 6000MT/s (~96GB/s) . The hardware design simulations indicate that achieving 6400MT/s (>100GB/s) is feasible; however, rigorous validation and software optimization are still required to ensure system stability and performance. This is why we’ve temporarily updated the product specifications to reflect the current stable bandwidth. Once the validation process is complete and stable firmware/software enabling 6400MT/s is available, we will update the specifications accordingly.
Regarding the CPU big core clock (2.6GHz / 2.8GHz) :
The CPU cores are designed to run at up to 2.8GHz , and internal tests indicate stable operation at this frequency under typical workloads. However, Cix has adopted a more conservative approach for now, officially listing the maximum clock frequency at 2.6GHz , to guarantee stability across various scenarios and workloads. We understand users desire the maximum potential from the hardware, and we’ll actively communicate with Cix about enabling stable higher clock rates through future firmware updates.
We believe that Cix has shown commendable dedication to the open-source community, actively investing in software ecosystem improvements. With continued collaboration, the Orion O6 and its Cix SoC platform have the potential to become one of the best-supported ARM-based open-source ecosystems available.
Additionally, Cix is a sponsor of the upcoming Linaro Connect 2025 event, “Boosting the Next Wave of Arm Innovation,” taking place from 14-16 May 2025 in Lisbon, Portugal . Radxa will also be sending engineers to participate. If you’re attending, this would be a great opportunity to engage directly with engineers from both Radxa and Cix in person.
Lastly, if you have already purchased an Orion O6 board and are dissatisfied with it, Radxa supports returns and will cover the return shipping costs.
Thanks again for your understanding and continued support. We’re committed to addressing your concerns and will keep the community updated with further developments.
