Intel Xeon Gold 5515+ 8c/16t 3.2GHz-4.1GHz 165W (PK8072205499500)

Intel Xeon Gold 5515+ — Technical Overview and Performance Insights

The Intel Xeon Gold 5515+ is an Emerald Rapids processor designed for enterprise environments requiring high per-core performance, strong memory bandwidth and modern PCIe 5.0 connectivity. With 8 cores and 16 threads operating at a 3.2 GHz base clock and boosting up to 4.1 GHz, it provides excellent responsiveness for latency-sensitive workloads.

The CPU features 2 MB of L2 cache per core and a shared 22.5 MB L3 cache, supporting applications with complex branching patterns and fragmented datasets. This architecture benefits API gateways, transactional applications, workflow engines and microservice orchestration systems where consistent single-thread performance is essential.

Support for eight-channel DDR5 memory up to 4400–4800 MT/s delivers substantially higher bandwidth compared to DDR4 platforms. Memory-intensive services such as JVM microservices, real-time analytics, caching layers and streaming engines benefit directly from these bandwidth improvements.

With 80 PCIe 5.0 lanes, the Xeon Gold 5515+ enables configurations with high-speed NVMe storage, 100/200G networking adapters, SmartNICs, DPUs and accelerators. This I/O flexibility allows the processor to serve as a strong foundation for edge appliances, virtualization clusters and hybrid compute-storage platforms.

The 165 W TDP ensures that the processor can maintain high frequencies while remaining efficient in dense dual-socket 1U/2U systems. In real-world deployments, it offers stable thermals and predictable performance across sustained workloads.

Overall, the Intel Xeon Gold 5515+ offers an excellent balance of high-frequency compute power, DDR5 bandwidth and PCIe 5.0 expansion. It is well suited for distributed enterprise systems, cloud-native workloads, telecom environments and latency-sensitive infrastructure.
