HP 733921B21 Network Server – Intel Xeon E5‑2620 v3 Processor Kit

The HP 733921B21 is a high‑performance processor kit designed for the HPE ProLiant DL180 Gen9 server chassis. It houses an Intel® Xeon E5‑2620 v3 CPU, delivering robust compute power, advanced memory bandwidth, and virtualization capabilities that empower modern data center workloads.

Core Architecture & Performance

The processor is built on Intel’s 22 nm Xeon E5 v3 family, featuring 6 physical cores (12 threads) that operate at a base frequency of 2.4 GHz. With Intel® Turbo Boost Technology 2.0, the CPU can dynamically elevate its clock speed up to 3.2 GHz, ensuring peak performance for bursty or single‑threaded tasks.

Its 64‑bit architecture supports modern operating systems and hypervisors, while the integrated L3 cache of 15 MB provides rapid access to frequently used data, reducing latency across compute-intensive applications.

Memory & Bandwidth Capabilities

The Xeon E5‑2620 v3 supports DDR4‑SDRAM memory modules. It can address a maximum of 786 432 MB (768 GB) of system RAM, thanks to its quad‑channel memory controller. The processor delivers an impressive 59 GB/s memory bandwidth, enabling high-throughput data processing and efficient handling of large datasets.

Bus & I/O Architecture

The CPU features a robust 8 GT/s QPI (QuickPath Interconnect) interface with two links, facilitating rapid communication between the processor and other system components. It supports up to 40 PCI Express 3.0 lanes, allowing for multiple high‑speed expansion cards such as SSDs, network adapters, or GPUs.

The processor’s PCIe 3.0 compatibility ensures that the server can leverage modern storage and networking technologies with maximum throughput.

Virtualization & Security Features

Intel® Virtualization Technology (VT‑x) and VT‑d are integrated into the CPU, enabling efficient hypervisor operation and direct memory access for virtual machines. This makes the HP 733921B21 an ideal choice for environments that require isolated workloads or rapid deployment of virtual servers.

Thermal Design & Power Efficiency

The processor’s TDP (Thermal Design Power) is 85 W, striking a balance between performance and energy consumption. Its voltage range (VID) spans from 0.65 V to 1.30 V, allowing the system firmware to adjust power delivery based on workload demands, thereby optimizing thermal output.

Compatibility & Scalability

This processor kit is specifically engineered for the HPE ProLiant DL180 Gen9 server platform. The single‑socket LGA 2011‑v3 design supports up to two CPUs per chassis, providing scalability for larger deployments while maintaining a compact footprint.

Instruction Set & Advanced Features

The CPU includes the AVX 2.0 instruction set, which accelerates vector operations common in scientific computing, machine learning, and media processing workloads. Combined with Intel® Turbo Boost, it delivers both raw compute power and efficient single‑thread performance.
