Processor Intel Xeon Silver 4209T 2,2 GHz 8 cores 11 MB LGA 3647

Processor Intel Xeon Silver 4209T operates at a base frequency of 2.2 GHz with up to 3.2 GHz Turbo Boost, offering 8 physical cores and 11 MB of shared cache. Built on the Cascade Lake microarchitecture for the LGA 3647 socket, this server/workstation CPU supports up to 1.02 TB of DDR4 memory across a hexa-channel memory architecture and includes advanced instruction set extensions such as AVX‑512 for compute‑intensive workloads. It does not include on‑board graphics and is intended for use in server and workstation environments.

Advantages

The Intel Xeon Silver 4209T provides hardware virtualization support (VT‑x, VT‑d, EPT) and security features including Intel® Trusted Execution Technology, Execute Disable Bit and AES‑NI for accelerated encryption. Performance features include Intel® Turbo Boost, Intel® Turbo Boost Max Technology 3.0, Hyper‑Threading, Speed Shift and Enhanced SpeedStep for dynamic power and frequency management. Additional enterprise features such as Intel® Run Sure Technology, Resource Director Technology (RDT), VMD and UPI links improve reliability, manageability and I/O performance in multi‑socket server platforms.
