Description
Product Description: Intel® Xeon® Silver 4309Y
Intel® Xeon® Silver 4309Y is a power-efficient 3rd generation Xeon Scalable server processor (Ice Lake architecture), ideal for virtualization, enterprise servers, cloud systems, and midrange data centers.
It features 8 cores and 16 threads, which ensures stable multithreading for tasks such as virtual machines, web services, containers, databases, and moderately loaded workloads.
The base processor frequency is 2.80 GHz, and thanks to Turbo Boost technology, the frequency can be increased to 3.60 GHz, providing good responsiveness even under peak loads.
Furthermore, the 4309Y supports up to 6 TB of DDR4 RAM, works with ECC memory, and supports up to 8 memory channels, ensuring high throughput and configuration reliability.
This processor is well suited for enterprise servers, virtualization, web hosting, cloud environments, entry-level/mid-range data centers, storage systems, and other applications where stability, ECC support, multitasking, and low power consumption are important.
