Intel has just released their Intel Xeon E7 v4 processors based on the latest Broadwell-EX architecture. Built on the 14nm process, these processors are the Xeon E7 4800 v4 and Xeon E7 8800 v4. Socket count starts out at 4 and can go up to 8, but with 3rd party node controllers, it can scale all the way up to 64 sockets. Each processor can handle up to 3TB of ram, with a maximum bandwidth of 102GB/s, and it can run on both DDR3 or DDR4. Minimum core count for the Xeon E7 is a 4 core and the highest you can get is a 24 core, with HyperThreading and has 60MB of LLC cache. Due to the large amounts of ram, these processors can handle.

Xeon E7 v4 CPUs now support 3DS load-reduced DIMMs. This allows for near real-time processing of in-memory workloads, thereby improving the performance and output for real-time data analytics. Such performance outputs are critical to certain market segments who rely on such data analytics to keep the operations running smoothly; they include the banking, power grid, telecommunication, and traffic control market segments.
