I have an Atom C2750 board (8 core), it runs at 2.4 GHz with only a heatsink and has a TDP of 20W. It&#x27;a much slower than current low-end desktop CPUs, but it runs circles around a Raspberry Pi 2. Its unique advantage for server loads is that the board holds 64GB ECC RAM. The Xeon-D is currently an even better option though, since some of the server boards with soldered CPUs can be kept fanless too (e.g. Supermicro X10SDV-4C-TLN4F ) despite 35W TDP and much better performance.
