Intel "Sapphire Rapids" Brings PCIe Gen 5 and DDR5 to the Data-Center

As if the mother of all ironies, prior to its effective death-sentence dealt by the U.S. Department of Commerce, Huawei's server business developed an ambitious product roadmap for its Fusion Server family, aligning with Intel's enterprise processor roadmap. It describes in great detail the key features of these processors, such as core-counts, platform, and I/O. The "Sapphire Rapids" processor will introduce the biggest I/O advancements in close to a decade, when it releases sometime in 2021.

With an unannounced CPU core-count, the "Sapphire Rapids-SP" processor will introduce DDR5 memory support to the data-center, which aims to double bandwidth and memory capacity over the DDR4 generation. The processor features an 8-channel (512-bit wide) DDR5 memory interface. The second major I/O introduction is PCI-Express gen 5.0, which not only doubles bandwidth over gen 4.0 to 32 Gbps per lane, but also comes with a constellation of data-center-relevant features that Intel is pushing out in advance as part of the CXL Interconnect. CXL and PCIe gen 5 are practically identical.

Intel "Cooper Lake" Latest 14nm Stopgap Between "Cascade Lake" and "Ice Lake"

With no end to its 10 nm transition woes in sight (at least not until late-2019), Intel is left with refinement of its existing CPU micro-architectures on the 14 nanometer node. The client-desktop segment sees the introduction of the "Whiskey Lake" (aka Coffee Lake Refresh) later this year; while the enterprise segment gets the 14 nm "Cascade Lake." To its credit, Cascade Lake introduces a few major platform innovations, such as support for Optane Persistent Memory, silicon-level hardening against recent security vulnerabilities, and Deep Learning Boost, which is hardware-accelerated neural net building/training, and the introduction of VNNI (Variable Length Neural Network Instructions). "Cascade Lake" makes its debut towards the end of 2018. It will be succeeded in 2019 by Ice Lake the new "Cooper Lake" architecture.

"Cooper Lake" is a refresh of "Cascade Lake," and a stopgap in Intel's saga of getting 10 nm right, so it could build "Ice Lake" on it. It will be built on the final (hopefully) iteration of the 14 nm node. It will share its platform with "Cascade Lake," and so Optane Persistent Memory support carriers over. What's changed is the Deep Learning Boost feature-set, which will be augmented with a few new instructions, including BFLOAT16 (a possible half-precision floating point instruction). Intel could also be presented with the opportunity to crank up clock speeds across the board.
