When to choose the 678X
In Intel’s line-up this processor sits in a server processor. With 48 cores on the FCLGA4710 platform it suits dense virtualisation, databases and high-throughput compute, and its 300 W TDP sets the cooling and power budget for the node.
Platform & compatibility
The Intel Xeon 678X uses the FCLGA4710 socket on 1S platforms, supports DDR5(6400MT/s) MRDIMM(8000MT/s) MRDIMM(8000MT/s), with up to 8 memory channels, and up to 4 TB of memory, provides PCI Express 5.0 (128 lanes). Confirm the exact OEM platform, BIOS level and memory population for your workload before ordering.
Deployment notes
The 678X installs in a FCLGA4710 platform with up to 8 memory channels and up to 4 TB of memory. Intel AMX accelerates INT8 and BF16 AI inference directly on the CPU. Intel SGX provides application enclaves. It is launched as part of Intel® Xeon® 6 processors and is intended for dense virtualisation, databases and high-throughput compute.
