Ice Lake – 3rd generation Xeon Scalable server processors – BGA1526
Ice Lake-SP – 3rd generation Xeon Scalable server processors – LGA 4189-4 (1-2 socket systems, PCIe v4)
Cooper Lake – 3rd generation Xeon Scalable (server) processors – LGA 4189-5 (4/8 socket systems PCIe v3 only)
Cooper Lake debuts alongside Socket LGA4189, which technically comes in two flavors — LGA4189-4, and LGA4189-5. LGA4189-4 is intended for Ice Lake, while LGA4189-5 is for Cooper Lake. The difference comes down to PCIe version — LGA4189-4 supports PCIe 4.0, while LGA4189-5 is PCIe 3.0-only. Ice Lake Xeons should not be put in a Cooper Lake motherboard, but Cooper Lake can drop into an ICL motherboard without a problem.
