Recent Atoms (Goldmont) are pretty decent - out of order, x64, three instructions per clock (compared to Jaguar's two), SSE4.2 and seemingly free from the bus degradation flaw. You lose AVX, but get to keep AES-NI and gain accelerated SHA which is nice on a tiny server. I think firmware on the intel's side might be a limitation, as IIRC it now requires UEFI, while PCEngines relies on their legacy coreboot implementation (which is actually open so yay).
