Some of the chip improvements are reflected in the finer details. Some Xeon chips will support a version of DRAM DIMMs in which memory chips are stacked on top of each other in a 3D format. That memory type will be available in the future.
The Xeons also have new instructions that speed up security tasks like encryption and decryption. Lane said security tasks are being processed 70 percent faster.
Another interesting feature is the Resource Director Technology, which helps speed up virtualization. The technology has a cache allocation feature, which can give guaranteed cache space for high-priority virtual machines. It also helps in software-defined networking and NFV (network-function virtualization) environments, where high-priority data packets can be moved into the cache ahead of others.
An add-on card available at a later date will allow the implementation of Intel's proprietary OmniPath fabric interconnect, which boosts data transfer speeds between storage, memory, processors and other components. Intel has not shared details on the underlying technologies in OmniPath, which is targeted mostly at high-performance computing.
The chip's integrated networking, storage and I/O support are almost identical to the predecessor Haswell server chips. That's a trade-off Intel had to make to keep the new chips compatible with existing sockets in Haswell-based servers so upgrades are less costly for customers.
