Intel Alder Lake has a new power + efficiency core architecture. As I understand it, the Linux Kernel does not currently support it.
Could I still run Ubuntu LTS on this hardware. What would the implications be? Would the OS treat all cores the same or would the efficiency cores sit idle?
>Solution :
You can and I do run Ubuntu 20.04 on my Alder Lake system. As the kernel is unaware of the hybrid cores it does not run as fast as it can. But as soon as they have a kernel that does, I will upgrade mine to that kernel and re-run the benchmarks.
