AMD EPYC™ 96 Cores 9645 Server Processor With Zen 5 Architecture And 320W TDP

The AMD EPYC™ 9645 is a high-efficiency, 5th generation EPYC processor built on the "Zen 5" architecture. Designed to balance exceptional core density with optimized power consumption, this 96-core processor delivers outstanding performance per watt for scale-out cloud environments, enterprise virtualization, and energy-conscious data center deployments. It combines leadership compute throughput with a robust security and I/O feature set, making it an ideal choice for workloads that demand high core counts without sacrificing operational efficiency.

The EPYC 9645 harnesses the advanced "Zen 5" core architecture, manufactured on a 4nm process node, to deliver significant improvements in instructions per clock (IPC) and energy efficiency. With 96 cores and 192 threads, it provides massive parallel processing capabilities while maintaining a 320W thermal design point. The processor supports the AVX-512 instruction set, accelerating floating-point intensive operations, AI inference, and scientific computing tasks. Its efficient power envelope allows for high-density server configurations that reduce cooling requirements and total cost of ownership.

To support demanding data-centric applications, the EPYC 9645 integrates a high-bandwidth memory and I/O subsystem:

• Memory Support: 12-channel DDR5 memory with speeds up to 6000 MT/s, delivering exceptional memory bandwidth suitable for virtualized environments, in-memory databases, and real-time analytics.
• PCIe Connectivity: 128 lanes of PCIe® 5.0, providing ample throughput for modern GPUs, high-speed NVMe storage, and 400GbE networking. This I/O capability ensures that the processor can handle data-intensive workloads without bottlenecks.

The AMD EPYC 9645 incorporates a suite of technologies designed to optimize performance, security, and scalability:

• AMD Infinity Architecture: Enables efficient chip-to-chip communication, low-latency memory access, and scalable multi-socket performance.
• AMD Infinity Guard: A comprehensive set of hardware-based security features, including secure encrypted virtualization, to help protect sensitive data across cloud and on-premises environments.
• Energy-Efficient Design: The 320W TDP and flexible cTDP allow system builders to tailor power consumption to workload requirements, enabling higher rack density and improved PUE (Power Usage Effectiveness) in data centers.

This processor is optimized for a broad spectrum of enterprise and cloud workloads, including:

• Cloud & Virtualization: Delivers high VM density with consistent performance for multi-tenant environments.
• Enterprise Applications: Handles ERP, CRM, and database workloads with a balanced core and memory architecture.
• AI Inference: Well-suited for CPU-based inference for recommendation systems, image recognition, and natural language processing models.
• Scale-Out Infrastructure: Ideal for web servers, microservices, and distributed storage systems where efficiency and core count are paramount.
