Emerald Rapids is the codename for Intel's fifth generation Xeon Scalable server processors based on the Intel 7 node.^{[3] [4]} Emerald Rapids CPUs are designed for data centers; the roughly contemporary Raptor Lake is intended for desktop and mobile usage.^{[5] [6]} Nevine Nassif is a chief engineer for this generation.^[7]

Features

CPU

• Up to 64 Raptor Cove CPU cores per package^[8]
  • Up to 32 cores per tile, reducing the max tiles to two
• 5 MB of L3 cache per core (up from 1.875 MB in Sapphire Rapids)
• Speed Select Technology that supports high and low priority cores

I/O

• DDR5 memory support up to 8-channel DDR5-5600^[8]
• Up to 80 PCI Express 5.0 lanes^[8]
