The latest Intel Xeon D-1571 SoC, designed for high-density data-centers and micro-servers, sets a new benchmark for energy efficiency. If the fact that it's an SoC (a combination of CPU and chipset) wasn't enough, the chip also crams in 16 CPU cores based on the "Broadwell" architecture, with HyperThreading enabling 32 logical CPUs, running at 1.30 GHz clock speed, a dual-channel DDR4 memory controller that supports up to 128 GB ECC DDR4 memory, and 24 MB of shared L3 cache; all at a TDP rated at just 45W. On most high-density server boards, such as the X10SDV-series by Supermicro, the chip is cooled by a small fan-heatsink. Such specs won't come cheap. Server board vendors will buy the Xeon D-1571 at $1,222 a piece in 1000-unit quantities.
