Processor Intel Xeon Gold 5515+ 3.2 GHz 22.5 MB LGA 4677

HP Enterprise Processor Intel Xeon Gold 5515+ 3.2 GHz 22.5 MB LGA 4677 is a server-class CPU designed for multi-socket and single-socket enterprise systems. Operating at a base frequency of 3.2 GHz with a boost up to 4.1 GHz and an integrated 22.5 MB cache, this Xeon Gold model delivers consistent compute for virtualization, database workloads and compute‑intensive services. The processor supports octa-channel DDR5 memory configurations up to 4 TB and includes advanced instruction set extensions such as AMX, AVX, AVX2, AVX‑512 and SSE4.2. Security and acceleration features include Intel SGX with a maximum enclave size of 128 GB, Intel QuickAssist Technology and Dynamic Load Balancer. The CPU uses the LGA 4677 (Socket E) platform and does not provide integrated graphics.

Advantages

The Xeon Gold 5515+ provides a balance of single‑threaded frequency and multi‑core efficiency with 8 processor cores and a 22.5 MB cache, which helps reduce memory access latency for server workloads. Support for octa‑channel DDR5 and up to 4 TB of memory enables large in‑memory datasets and high concurrency. Advanced vector and matrix instruction support (AVX, AVX2, AVX‑512, AMX) improves performance on numerical, AI and media processing tasks. Built‑in security and acceleration features such as Intel SGX and QuickAssist Technology increase data protection and cryptographic offload capabilities in enterprise environments.

Suitable for

• Virtualization hosts and hyperconverged infrastructure
• Database servers and in‑memory analytics

How to use

Install the processor into a compatible server motherboard with LGA 4677 socket following the server manufacturer’s mounting and thermal guidelines. Apply an appropriate thermal solution and ensure proper airflow in the chassis to maintain safe operating temperatures under sustained loads. Configure server firmware and operating system to support the processor’s features, enable relevant instruction set extensions and platform accelerations, and populate DDR5 memory channels to take advantage of octa‑channel bandwidth and large memory capacity.

Usage recommendations

For optimal performance, use balanced memory configurations across all memory channels and verify firmware/platform support for AVX‑512 and AMX instructions. Allocate sufficient cooling and power headroom in multi‑processor systems, and enable SGX and QuickAssist features in the platform firmware only if the workload and software stack require hardware enclave or cryptographic acceleration.
