Architecture[edit]

Key changes from Saphire Rapids[edit]

New instructions[edit]

Sierra Forest is set to introduce new instructions:

  • CMPCCXADD - Compare and Add if Condition is Met
  • AVX IFMA - Integer Fused Multiply Add
  • AVX VNNI INT8 - AVX Vector Neural Network Instructions INT8
  • LASS - Linear Address Space Separation

This list is incomplete; you can help by expanding it.

Products[edit]

Sierra Forest-SP[edit]

  • Sierra Forest-SP (Scalable Performance) uses the Beechnut City platform
with the smaller LGA 4710 socket, targeted towards mainstream server.
Sierra Forest-SP features up to 144 E-cores and eight-channel DDR5 memory support.

Sierra Forest-AP[edit]

  • Sierra Forest-AP uses the Avenue City platform with the larger
LGA 7529 socket for higher core count SKUs up to 288.
It supports a higher number PCIe lanes and 12-channel DDR5 memory.
