Description

The Intel Xeon 6766E 144-Core Processor is a high-density Sierra Forest E-core CPU engineered for HPE ProLiant Gen12 servers, delivering exceptional throughput for cloud, virtualisation, and data centre workloads. Running at a 1.9GHz base and 2.7GHz turbo frequency with a 250W TDP, its 144-core architecture maximises core-per-socket density — ideal for scale-out infrastructure where parallel compute and energy efficiency are critical.

Built on Intel's 5nm process and housed in Socket FCLGA4710, the Xeon 6766E supports eight-channel DDR5-6400 memory (up to 1TB), 88 PCIe 5.0 lanes, and hardware-accelerated workloads via built-in DSA, IAA, QAT, and DLB engines. Intel TDX provides hardware-based confidential computing for sensitive workloads. Need it fast? iptrading.com.au delivers across Australia — shop now.
