Conclusion

From the above results, it can be seen that the MILK-V Pioneer is surely faster with 64 cores. However, due to low software support, kernel upgrades, and (to some extent) hardware limitations, it is still not ready for an apple-to-apple comparison with ARM or x86 architectures of the same computing power.
