True, but I didn’t say that the chip wasn’t interesting. What I said is that it’s not that attractive (to the real market for these: micro servers). The dual 10Gig Ethernet and 8 SATA 3.0 ports are interesting. You won’t get that with a C2K system at 25W TDP, (4 x GigE that can run at 2.5Gbps per port, and 2 SATA 3.0 ports currently) but Intel owns IP for both, so if that becomes a differentiator for design wins, I’d expect a future variant to cover. But by all means, port FreeBSD to it. Perhaps it can be the long-desired “reference platform” to bring ARM into a “Tier 1” architecture status. Jim
