Intel Xeon Platinum 8173M 28-Core 56-Thread Enterprise Server Processor

The Intel Xeon Platinum 8173M is a high-core-count enterprise server processor based on Intel's first-generation Xeon Scalable Skylake-SP architecture. Featuring 28 physical cores and 56 processing threads, it is designed for demanding multi-threaded workloads such as virtualization, cloud computing, database servers, enterprise applications and high-performance computing.

The Xeon Platinum 8173M operates at a 2.00GHz base frequency with Turbo frequencies reaching up to approximately 3.50GHz. It includes 38.5MB of L3 cache, uses the FCLGA3647 socket and has a 165W TDP.

28 Cores / 56 Threads

With 28 physical processor cores and Intel Hyper-Threading Technology providing 56 processing threads, the Platinum 8173M provides substantial parallel computing capability for workloads that can take advantage of large numbers of CPU cores.

2.00GHz Base & Up to 3.50GHz Turbo

The processor operates at a base frequency of 2.00GHz and is commonly documented with a maximum Turbo frequency of up to 3.50GHz. This combination prioritizes high multi-core throughput while providing additional clock speed for workloads using fewer cores.

38.5MB L3 Cache

A large 38.5MB shared L3 cache helps reduce memory-access latency and supports data-intensive enterprise workloads, virtualization, databases and multi-user server applications.

Skylake-SP Architecture

The Xeon Platinum 8173M belongs to Intel's first-generation Xeon Scalable processor platform based on the Skylake-SP architecture and 14nm manufacturing process.

FCLGA3647 Server Socket

The processor uses Intel's FCLGA3647 socket and requires a compatible Xeon Scalable server motherboard. It is not compatible with older LGA2011, LGA2011-3 or conventional desktop CPU sockets.

6-Channel DDR4 Memory Architecture

The Skylake-SP platform provides six memory channels per processor. The 8173M is commonly documented with support for DDR4 memory speeds up to 2666 MT/s and large enterprise memory configurations, subject to motherboard, BIOS and DIMM compatibility.

PCI Express 3.0

The Xeon Scalable platform provides PCI Express 3.0 connectivity for high-speed server components such as NVMe storage, network adapters, RAID controllers, accelerators and GPUs.

Intel AVX-512

The Skylake-SP Xeon Platinum platform supports Intel AVX-512 instruction extensions, providing enhanced vector-processing capability for compatible scientific, engineering, analytics and high-performance computing applications.

Enterprise Virtualization

The combination of 28 cores and 56 threads makes the 8173M particularly attractive for virtualization environments where a large number of virtual machines, containers or simultaneous workloads need to run on a single physical server.

OEM Processor Information

The Xeon Platinum 8173M is an OEM-oriented processor and is not presented like Intel's standard retail Xeon Scalable SKUs in the current Intel product catalog. Because OEM server processors can have platform-specific BIOS and firmware requirements, compatibility should be checked carefully before installation.
