Intel's Ultra Low-Voltage Chips for Micro-Servers

The good: the announced chips support 64-bit, visualization, and ECC, 8MB cache, and plenty of PCIe lanes. Decent clock speeds topping out at almost 4GHz.

The bad: Maximum 32GB ram. Only a single CPU socket supported per system.

Next year there will be Atom-based versions. Overall I these will beat the current Xeons in Performance/Watt but will probably beat them on price judging from the platform limitations.

It seems like a cautious, low-risk move into what could be a quickly growing new market depending on the next moves by AMD/Nvidia/ARM/etc.
