When to choose the 6756E
In Intel’s line-up this processor sits in a server processor. With 128 cores on the FCLGA4710 platform it suits dense virtualisation, databases and high-throughput compute, and its 225 W TDP sets the cooling and power budget for the node.
Platform & compatibility
The Intel Xeon 6756E uses the FCLGA4710 socket on 2S platforms, supports DDR5-6400, with up to 8 memory channels, and up to 4 TB of memory, provides PCI Express 5.0 (88 lanes). Confirm the exact OEM platform, BIOS level and memory population for your workload before ordering.
Deployment notes
The 6756E installs in a FCLGA4710 platform with up to 8 memory channels and up to 4 TB of memory. Intel TDX adds hardware-isolated confidential-computing virtual machines. Intel SGX provides application enclaves. Intel QuickAssist (QAT) offloads compression and cryptography (2 default devices). It is launched as part of Intel® Xeon® 6 processors and is intended for dense virtualisation, databases and high-throughput compute.
