Designed for server applications, it supports up to 6.14 TB of DDR4-SDRAM memory across octa-channel architecture. With a 10 nm lithography and LGA 4189 socket, it is optimized for scalability with support for 2S configurations. The processor also supports advanced instruction sets including SSE4.2, AVX, AVX 2.0, and AVX-512, making it suitable for demanding workloads.

## Long description

Intel Xeon Silver 4309Y is a server-class processor with a base frequency of 2.8 GHz and 12 MB cache, built on the Ice Lake microarchitecture for LGA 4189 platforms. Designed for use in single- and dual-socket (2S) server and workstation systems, it supports octa-channel DDR4 memory and advanced instruction sets including SSE4.2, AVX, AVX2 and AVX-512 to handle demanding, multi-threaded and virtualized workloads.
Advantages
The processor provides scalable performance for server environments by combining Turbo Boost capability for dynamic frequency increases, Hyper-Threading for parallel thread execution, and Intel Speed Shift for faster responsiveness on transient workloads. Virtualization features (VT-x, VT-d, EPT) and Resource Director Technology improve manageability and isolation of virtual machines and I/O devices, while Intel DL Boost and AVX-512 extensions accelerate AI inference and wide-vector computations.
Suitable for
Virtualized server hosts and hypervisor platforms
Enterprise databases and multi-threaded server applications
AI inference and high-performance vectorized computing
Storage servers using NVMe drives with hot-plug management (VMD)

Cache: 12 MB
Cores / Threads: 8 cores (supports Hyper-Threading for two threads per core)
Socket: LGA 4189
Microarchitecture: Ice Lake; Lithography: 10 nm
Memory: Octa-channel DDR4 (supports up to multi-terabyte configurations; product summary lists up to 6.14 TB support)
Instruction set & extensions: SSE4.2, AVX, AVX2, AVX-512, Intel DL Boost (VNNI)
Server features: Turbo Boost, VT-x, VT-d, EPT, Speed Shift, Speed Select Performance Profiles, Resource Director Technology, Volume Management Device (VMD)
How to use
Install the processor into a compatible LGA 4189 motherboard following the server or workstation vendor instructions and use an appropriate cooling solution rated for the platform TDP. Configure BIOS/firmware options for dual-socket operation if deploying in a 2S system, and enable virtualization and performance profile features (VT-x, VT-d, Speed Select, RDT) as required by your workloads. Populate memory channels according to the motherboard manual to take advantage of the octa-channel DDR4 architecture.
Usage recommendations
For virtualized or I/O-intensive environments, enable VT-d and VMD in firmware to improve device isolation and NVMe management. Use BIOS tuning to balance Performance Profile settings and RDT controls for optimal cache and memory bandwidth allocation between VMs and containers.
