Intel Xeon Gold 5415+ 8c/16t 2.9GHz-4.1GHz 150W (PK8071305118701)

Intel Xeon Gold 5415+ — Technical Overview and Performance Insights

The Intel Xeon Gold 5415+ is a high-frequency Sapphire Rapids processor designed for applications where per-core performance and low latency are more important than high core count. With 8 cores and 16 threads operating at a 2.9 GHz base clock and boosting up to 4.1 GHz, it is well suited for API front ends, telecom services, financial systems, CDN nodes and edge deployments.

Architectural improvements in Sapphire Rapids deliver a noticeable IPC uplift compared to previous Xeon generations. Combined with 2 MB of L2 cache per core and a shared 22.5 MB L3 cache, the processor maintains stable behavior under microservice-heavy and transaction-driven workloads. Its frequency profile provides consistent responsiveness even when multiple service layers share the same socket.

The Xeon Gold 5415+ supports eight-channel DDR5 memory up to 4400 MT/s, offering significantly higher bandwidth and improved latency compared to DDR4 platforms. This benefits JVM-based applications, in-memory caches, distributed key-value stores and real-time analytics pipelines that rely on strong memory throughput.

The CPU includes 80 PCIe 5.0 lanes, allowing integration of high-speed NVMe storage, 100/200G networking interfaces, accelerators and SmartNIC/DPU solutions. For mid-range datacenters and edge appliances, this level of I/O flexibility is often more valuable than raw thread count, enabling sophisticated storage, networking and compute configurations.

With a 150 W TDP, the processor strikes a balance between high per-core output and manageable cooling requirements. OEM benchmarks show that dual-socket configurations deliver predictable latency and excellent performance in vertically scaled applications where individual threads do most of the work.

Overall, the Intel Xeon Gold 5415+ is ideal for organizations upgrading from older DDR4-based systems or deploying workloads that depend on fast single-thread performance, high-bandwidth memory and advanced PCIe 5.0 connectivity. Its efficiency, low latency and modern architecture make it a compelling choice for cloud-native, telecommunications and distributed enterprise environments.
