Description

24-core 4th Gen Intel Xeon Scalable (Gold 6418H) processor option for HPE servers, balancing core count and per-core frequency with a 2.1 GHz base and 185W TDP. It is well-suited for cloud-native services, virtualization clusters, and mixed enterprise workloads. DDR5 memory, PCIe 5.0 connectivity, and accelerators (AVX-512, Intel AMX, DL Boost) enhance performance on HPE ProLiant Gen11 platforms.

Features

Balanced 24-core configuration for mixed enterprise and cloud-native workloads
- High bandwidth with 8-channel DDR5 and PCIe 5.0 expansion
- Accelerated AI and analytics via Intel AMX, AVX-512, and DL Boost
- Enterprise security and virtualization capabilities (Intel TME, AES-NI, VT-x/VT-d)
- Designed for HPE ProLiant Gen11 server ecosystems

FAQs

Q: What does the 'H' suffix indicate for 6418H?
A: It signifies a performance-focused SKU with higher base frequencies relative to non-H counterparts.

Q: Can I mix this CPU with different Xeon models in the same server?
A: No. Both processors in a multi-CPU system must be identical in model, core count, and stepping.

Q: Which memory types and speeds are supported?
A: DDR5 RDIMMs up to 4800 MT/s; actual speed varies with DIMM type and population.

Q: How many PCIe lanes are available from the CPU?
A: Up to 80 PCIe 5.0 lanes, with platform-dependent allocation and bifurcation.

Q: Is this option validated for HPE ProLiant Gen11?
A: Yes, for Gen11 models that support LGA4677. Confirm support in the server’s QuickSpecs.
