The Intel Xeon D Review: Performance Per Watt Server SoC Champion?

Anandtech published The Intel Xeon D: Performance Per Watt Server SoC Champion? A quote from the article:
Eight 14nm Broadwell cores, a shared L3-cache, dual 10 gigabit MAC, a PCIe 3.0 root with 24 lanes and a lot more find a home in Intels most powerful server SoC ever, the Xeon D-1540. Thanks to Supermicros 5028D-TN4T superserver, we are able to compare the latest Xeon with the Atom C2000 SoC, low power Xeon E5s and the Xeon E3-1200 v3. 

The days that Intel neglected the low end of the server market are over. The most affordable Xeon used to be the Xeon E3: a desktop CPU with a few server features enabled and with a lot of potential limitations unless you could afford the E5 Xeons. The gap, both in performance and price, between Xeon E3 and E5 is huge. For example - a Xeon E5 can address up to 768 GB and the Xeon E3 up to 32 GB. A Xeon E5 server could contain up to 36 cores, whereas Xeon E3 was limited to a paltry four. And the list is long: most RAS features, virtualization features were missing from the E3, along with a much smaller L3-cache. On those terms, the Xeon E3 simply did not feel very "pro".

Luckily, the customers in the ever expanding hyperscale market (Facebook, Amazon, Google, Rackspace and so on) need Xeons at a very large scale and have been demanding a better chip than the Xeon E3. Just a few months ago, the wait was over: Xeon D fills the gap between the Xeon E3 and the Xeon E5. Combining the most advanced 14 nm Broadwell cores, a dual 10 gigabit interface, a PCIe 3.0 root with 24 lanes, USB and SATA controllers in one integrated SoC, the Xeon D has excellent specs on paper for everyone who does not need the core count of the Xeon E5 servers, but who simply needs 'more' than the Xeon E3.
