The Intel Xeon Platinum 8165 is a high-end, enterprise-grade server processor from the Skylake-SP family, designed for mission-critical data center workloads, cloud infrastructure, analytics, and virtualization. With 24 physical cores and 48 threads, it delivers massive parallel processing power for highly demanding multi-threaded environments.
Running at a base clock of 2.30 GHz and boosting up to 3.70 GHz, this CPU combines high core density with robust single-core performance. Its 33 MB of L3 cache ensures efficient data sharing across cores and accelerates memory-dependent workloads. The 205W TDP underscores the processor’s high power envelope, tuned for heavy compute usage in large-scale server deployments.
The 8165 supports six-channel DDR4 memory, enabling up to 1.5 TB of RAM. It supports Intel Optane persistent memory, advanced virtualization, and Intel’s AVX-512 instruction set for compute acceleration. With 48 PCIe 3.0 lanes per socket, it offers high throughput for I/O-intensive applications.
