Even knowing nothing about performance, knowing that it is N6 means it probably isnt particularly power efficient (as compared to leading edge x86/ARM).

That chip is actually reasonably power efficient, not very far away from leading edge x86 assuming 180W TDP. At 120W, the RISC-V server is on par or even exceeds the power efficiency of the x86 system.

According to that graph, the P870 has 80% of the performance of Ice Lake.
