At its Data-Centric Innovation Summit in Santa Clara today, Intel unveiled its official Xeon roadmap for 2018 – 2019. As expected, the company confirmed its upcoming Cascade Lake, Cooper Lake-SP and Ice Lake-SP platforms.
Later this year Intel will release its Cascade Lake server platform, which will feature CPUs that bring support for hardware security mitigations against side-channel attacks through partitioning. In addition, the new Cascade Lake chips will also support AVX512_VNNI instructions for deep learning (originally expected to be a part of the Ice Lake-SP chips, but inserted into an existing design a generation earlier).
Moving on to the next gen. Intel’s Cooper Lake-SP will be launched in 2019, several quarters ahead of what was reported several weeks ago. Cooper Lake processors will still be made using a 14 nm process technology, but will support some functional improvements, including the BFLOAT16 feature. By contrast, the Ice Lake-SP platform is due in 2020, just as expected.
One thing to note about Intel’s Xeon launch schedules is that the Cascade Lake will ship in Q4 2018, several months from now. Normally, Intel does not want to create internal competition and release new server platforms too often. That said, it sounds like we should expect Cooper Lake-SP to launch in late 2019 and Ice Lake-SP to hit the market in late 2020. To make it clear: Intel has not officially announced launch timeframes for its CPL and ICL Xeon products and the aforementioned periods should be considered as educated guesses.
Intel’s Server Platform Cadence
Platform Process Node Release Year
Haswell-E 22nm 2014
Broadwell-E 14nm 2016
Skylake-SP 14nm+ 2017
Cascade Lake-SP 14nm++? 2018
Cooper Lake-SP 14nm++? 2019
Ice Lake-SP 10nm+ 2020
While the Cascade Lake will largely rely on the Skylake-SP hardware platform introduced last year (albeit with some significant improvements when it comes to memory support), the Cooper Lake and Ice Lake will use a brand-new hardware platform. As discovered a while back, that Cooper Lake/Ice Lake server platform will use LGA4189 CPU socket and will support an eight-channel per-socket memory sub-system.
