Lenovo 4XG7A83805 THINKSYSTEM SR630 V3 Intel Xeon content_copy

The Lenovo Intel Xeon Gold 6448Y is a server processor of the 4th generation of the Intel Xeon Scalable family, specifically designed for use in server and enterprise environments. It is based on the codename Sapphire Rapids and is designed for high-performance applications requiring high computing power, scalability, and security. The processor features 32 cores and 64 threads, making it suitable for parallel workloads and virtual environments. It operates at a base frequency of 2.1 GHz and reaches a boost frequency of 4.1 GHz when needed, allowing it to dynamically adapt to the respective load. The TDP is 225 W, indicating high power consumption and requiring appropriate cooling.

Applications

The processor is intended for use in servers and enterprise environments, particularly in systems requiring high computing power, large memory capacities, and high availability. It is suitable for applications such as databases, virtualization, cloud infrastructures, big data analytics, and security solutions. The support for Intel® Optane™ DC Persistent Memory also enables the use of persistent memory architecture, which offers advantages for certain workloads.

Features and Specifications in Detail

The Intel Xeon Gold 6448Y supports an octa-channel memory bus, enabling up to 6 TB of DDR4-SDRAM, with ECC memory support to ensure data integrity. The processor architecture provides 80 PCI-Express lanes in version 5.0, enabling high bandwidth for external devices and interfaces. Support for Intel® Hyper-Threading Technology and Intel® Turbo Boost Technology 2.0 ensures efficient utilization of computing resources. Additionally, features such as Intel® AES-NI, Intel® Total Memory Encryption, and Intel® Software Guard Extensions (SGX) are integrated, supporting data encryption and security during operation.

Technology Explained Simply

The processor uses the LGA 4677 (Socket E) socket technology, developed for the 4th generation of Intel Xeon Scalable processors. The 60 MB cache memory supports fast data processing, while the system bus rate of 16 GT/s ensures high data transfer rates between CPU and memory. The cores are divided into two priority levels: 12 cores at 2.4 GHz and 20 cores at 2 GHz, enabling efficient load distribution. Support for instruction sets such as AVX-512, AMX, and SSE4.2 extends capabilities for scientific computing, artificial intelligence, and machine learning.

Compatibility and Accessories

The processor is scalable for 2-socket systems and supports embedded options, making it suitable for modular server architectures. It is specifically designed for Lenovo ThinkSystem servers such as the SR630 V3, although exact compatibility with the respective server model should be verified. Support for Intel® Speed Select Technology enables flexible adjustment of performance profiles, allowing operation to be adapted to specific requirements.

Installation and Mounting

Installation is performed in an LGA 4677 socket, with the exact mounting instructions corresponding to the respective server model. The Tcase operating temperature is 79 °C, while the maximum DTS value is 92 °C, defining the thermal limits of the processor.

Advantages in Operation

The processor offers high computing power with 32 cores and 64 threads, supports large memory capacities, and provides advanced security features. The integration of technologies such as Intel® Deep Learning Boost and Intel® Resource Director Technology enables optimized resource utilization. Scalability to 2 sockets and support for PCI-Express 5.0 ensure high flexibility and performance in modern server environments. Support for Intel® Optane™ DC Persistent Memory extends memory architecture for specific use cases.
