Here's Micron on Ice Lake Xeon - also note DDR5 as well - probably for next year for
DDR5 and Ice Lake should be only in a few months:
<< This quarter, we started early sampling of 1z DDR5 for enterprise applications. Additionally, we also started sampling our higher-frequency DDR4 modules for Intel’s Ice Lake server platform, which we expect to drive server DRAM content growth.>>
Here's some info on the Intel side
<<Intel Xeon 10nm+ Ice Lake-SP/AP Family
Intel Ice Lake-SP processors will be available in the third quarter of 2020 and will be based on the 10nm+ process node. We have seen earlier slides say that the Ice Lake family would feature up to 28 cores but the one from ASUS's presentation says that it would actually feature up to 38 cores & 76 threads per socket.
The main highlight of Ice Lake-SP processors will be support for PCIe Gen 4 and 8-channel DDR4 memory. The Ice Lake Xeon family would offer up to 64 PCIe Gen 4 lanes and would offer support for 8-channel DDR4 memory clocked at 3200 MHz (16 DIMM per socket with 2nd Gen Persistent memory support). Intel Ice Lake Xeon processors would be based on the brand new Sunny Cove core architecture which delivers an 18% IPC improvement versus the Skylake core architecture that has been around since 2015.>>
