SRPLX Intel Xeon 4-Core 6315p 2.8GHz Base Clock 4 Threads 12MB Cache 55W Processor.

Energy-Efficient Performance for Specialized Workloads

The 6315P stands out for its low power consumption profile with just 55W TDP, making it ideal for hyperscale and edge computing environments where thermal efficiency is critical. While not the highest core count processor in Intel's Xeon family, the 4-core architecture provides exceptional thread isolation and latency performance for workloads that benefit from consistent single-thread operation, such as certain real-time analytics and network function virtualization.

Category Positioning: Entry-Level Xeon Scalable CPUs

The Intel Xeon 6315P belongs to the entry-level tier of the 3rd Gen Intel Xeon Scalable family, known as the Ice Lake-SP generation. These CPUs support numerous server-grade technologies like AVX-512, DL Boost, and Intel Speed Select, which are typically found in more powerful counterparts but are scaled appropriately in the 6315P to suit its 4-core architecture.

Scalability and Flexibility

Designed for single-socket systems, the 6315P provides scalable server performance while minimizing infrastructure complexity. It supports up to 8 memory channels and integrates Intel’s advanced technologies such as:

• Intel® Turbo Boost Technology 2.0
• Intel® Hyper-Threading Technology (Disabled in this variant)
• Intel® Deep Learning Boost (VNNI)
• Intel® AES-NI for cryptographic acceleration

Ideal Use Cases

Though compact in core count, the Intel Xeon 6315P excels in scenarios such as:

• Edge servers and remote office infrastructure
• Lightweight database servers
• Cloud-native microservices
• Load balancers and web application firewalls
• HCI nodes requiring energy efficiency

Technical Features and Architecture

Ice Lake-SP Foundation

Built on the 10nm process, Ice Lake-SP introduces numerous improvements in terms of memory support, PCIe lane count, and AI workload acceleration. The Xeon 6315P benefits from:

• PCIe Gen 4.0 with up to 64 lanes for high-speed peripheral connectivity
• DDR4-3200 MT/s memory compatibility with ECC support
• Support for up to 6TB of system memory on select platforms

Cache & Latency Optimization

With a 12MB L3 cache, the Intel Xeon 6315P offers ample space for frequently accessed data, reducing memory fetch times and improving overall application responsiveness. Combined with Intel’s Smart Cache technology, the processor dynamically allocates cache where needed for optimized compute cycles.

Security and Data Integrity

Intel integrates a wide array of hardware-level security features into the 6315P, including:

• Intel® Software Guard Extensions (SGX)
• Intel® Trusted Execution Technology (TXT)
• Secure Key and Boot Guard support
• Total Memory Encryption (TME)

These features are critical for compliance-driven industries such as finance, healthcare, and government computing.

Compatibility and Platform Support

The SRPLX 6315P CPU is compatible with Intel’s C620A series chipsets and various OEM platforms supporting the LGA4189 socket. It is well-suited for rackmount, tower, and custom appliance-based server installations.

Market Comparisons

Xeon 6315P vs. AMD EPYC Entry-Level CPUs

While AMD’s EPYC 7002 and 7003 series often offer more cores at comparable price points, the Intel 6315P’s advantage lies in software ecosystem compatibility, low-latency per-core performance, and Intel’s extensive partner ecosystem. Enterprises running Intel-optimized applications or using virtualization platforms like VMware or Hyper-V can leverage better optimization with Xeon processors.

Xeon 6315P vs. Higher Core Xeons

Compared to 8- or 16-core Xeons in the same generation, the 6315P offers superior price-to-performance efficiency for specific single-threaded or lightly threaded workloads. Its 55W power consumption also means significantly lower thermal design requirements and smaller power supply units, which reduces overall TCO (total cost of ownership).

Environmental & Operational Efficiency

Low Power and Cooling Requirements

With a TDP of just 55 watts, the Intel Xeon 6315P minimizes heat generation. This makes it an ideal choice for edge deployments, micro data centers, and energy-constrained environments where passive or semi-active cooling systems are preferred.

Reliability and Uptime Support

The processor includes support for ECC memory and advanced RAS (Reliability, Availability, and Serviceability) features, ensuring high system uptime and robust error correction during continuous operations.

Deployment Considerations

Form Factor Compatibility

The Xeon 6315P is primarily deployed in 1U or 2U rackmount servers, integrated appliances, or energy-optimized tower servers. System builders favor this CPU for its:

• Efficient power draw
• Thermal flexibility
• Compatibility with wide platform vendors like Supermicro, Dell EMC, and HPE

Lifecycle and Availability

Released as part of the 3rd Gen Xeon Scalable series, the 6315P enjoys long-term supply chain support and validated BIOS/firmware updates from major OEM vendors. It is designed for enterprise lifecycle longevity and can be deployed in high-reliability infrastructure scenarios.
