The Intel Xeon E5-2609 v3 SR1YC 6-Core 1.90GHz Processor 

The SR1YC Intel Xeon E5-2609 v3 6-Core 1.90GHz 6.40GT/s QPI 15MB L3 Cache Socket LGA2011-3 Processor stands as a dependable choice within the family of data-center-grade CPUs engineered for stability, predictable workload performance, and efficient resource allocation in medium to large enterprise environments. Positioned within the broader Intel Xeon E5 v3 architecture, this processor is widely embraced in multi-socket servers and scalable computing platforms that demand consistent uptime and balanced computational power. Its methodology incorporates a combination of six physical cores, a substantial 15MB shared Smart Cache, and Intel’s advanced 22nm process technology, culminating in a server CPU ideal for virtualization clusters, application servers, database layers, and mid-tier cloud infrastructures.

Interconnect Capabilities

The Intel Xeon E5-2609 v3 integrates advanced interconnect technology designed to boost communication efficiency between CPU cores, memory, and chipset components. Its QuickPath Interconnect (QPI) ensures fluid data transmission in multi-CPU configurations.

Power Efficiency and Voltage Features

The processor combines controlled thermal output with dynamic voltage ranges to provide strong performance while reducing energy waste. Its TDP level makes it suitable for rack servers, tower units, and blade configurations.

Socket and Platform Compatibility

The SR1YC Xeon E5-2609 v3 integrates into the LGA 2011-3 platform, delivering strong compute functionality across workstations, virtualization layers, and cloud infrastructure. Its architectural design ensures seamless operation inside scalable data systems.

Six Physical Cores

The processor incorporates six physical, non-Hyper-Threaded cores, offering straightforward yet consistent multi-core performance. This core configuration is particularly advantageous for workloads benefiting from parallel execution such as file hosting, storage controllers, DNS servers, ERP systems, and digital asset management platforms. By avoiding Hyper-Threading, the CPU maintains predictable performance with minimal thread scheduling overhead, a trait appreciated in real-time or latency-sensitive server applications.

1.90GHz Base Frequency and 6.40GT/s QPI Speed

Although the 1.90GHz base frequency may appear modest compared to higher-tier Xeon counterparts, its architecture compensates through improved instructions-per-cycle efficiency and robust QPI bandwidth. The 6.40GT/s QuickPath Interconnect keeps inter-processor communication steady, enabling balanced performance in dual-socket environments where data exchange consistency is paramount. Applications depending on coherency across sockets—such as distributed memory operations, large dataset retrieval, and virtualization host pooling—benefit greatly from this QPI speed.

15MB L3 Smart Cache 

The sizable 15MB L3 Smart Cache subsystem facilitates fast retrieval of frequently accessed instructions and data sets. This caching efficiency dramatically reduces memory latency in intensive workloads like web hosting, analytics processing, and business logic execution. Applications that handle repetitive data sequences or multi-user simultaneous requests experience considerable throughput stability due to this enhanced caching capability.

Socket LGA2011-3 Platform

Designed for motherboards utilizing the Socket LGA2011-3 infrastructure, the SR1YC belongs to a class of processors compatible with powerful Intel C610 series chipsets. This socket standard is widely adopted in enterprise-grade server platforms, offering long-term scalability, diverse upgrade paths, and modular hardware support. The LGA2011-3 ecosystem accommodates numerous memory configurations, multi-socket arrangements, and advanced I/O expansions including SAS controllers, NVMe backplanes, and multi-Gigabit Ethernet adapters.

Compatibility With DDR4 Memory

A defining highlight of this processor category is support for DDR4 memory modules. Compared to DDR3 predecessors, DDR4 offers superior bandwidth, lower voltage consumption, and enhanced reliability features. With speeds reaching up to 2133 MT/s, organizations witness improved multitasking, quicker data throughput, and smoother application scaling even under heavy loads.

Dual-Socket Expandability

The SR1YC processor is optimized for deployment in dual-socket servers, allowing effective doubling of computational resources. This makes it particularly suited for IT infrastructures where server density and compute scaling are vital. Environments such as virtualization clusters, high-availability database replication nodes, and cloud service platforms gain exceptional value when combining two processors in the same system.
