Processor Intel Xeon Bronze 3408U 1.8 GHz 22.5 MB LGA 4677

Processor Intel Xeon Bronze 3408U operates at a base frequency of 1.8 GHz with a boost up to 1.9 GHz and includes 22.5 MB of last-level cache. Designed for the LGA 4677 (Socket E) platform, this 8-core server CPU supports octa-channel DDR4 memory up to 6 TB and advanced instruction sets such as AMX, SSE4.2, AVX, AVX2 and AVX-512. The processor also supports Intel® SGX for creating hardware-enforced secure enclaves (up to 64 GB) and includes multiple platform technologies for virtualization, security and performance optimization.

Advantages

The Intel Xeon Bronze 3408U combines multi-core processing with a large shared cache and wide memory bandwidth to handle server and enterprise workloads. Built-in virtualization features (VT-x, VT-d, EPT) and management technologies improve isolation and resource allocation for virtual machines and containers. Hardware security features such as Intel® SGX, Execute Disable Bit, Intel® Boot Guard and Total Memory Encryption reduce exposure to attacks and protect sensitive data. Advanced instruction extensions including AVX-512, DL Boost and AES-NI accelerate cryptographic, AI inference and vectorized computations.

Suitable for

• Enterprise servers and rack-mounted compute nodes
• Virtualized environments and hyperconverged infrastructure
• Data-processing workloads that benefit from AVX/AVX-512 and DL Boost
• Secure computing with hardware enclaves and encrypted memory
• Memory-intensive applications requiring large DDR4 capacity

How to use

Install the processor into a compatible LGA 4677 (Socket E) motherboard following the motherboard and CPU vendor instructions. Ensure adequate cooling and power delivery for server-grade operation. Configure BIOS/UEFI options to enable or tune virtualization (VT-x, VT-d, EPT), security features (SGX, Boot Guard, TME) and performance technologies (Turbo Boost, Speed Shift) as required by the workload. Populate memory channels according to the motherboard manual to achieve octa-channel bandwidth and configure ECC settings if supported.

Recommendations

For server deployments, use validated server motherboards and firmware, enable hardware security features when handling sensitive data, and match cooling and power capacity to expected workloads. For virtualized or AI inference tasks, ensure the operating system, hypervisor and drivers support AVX-512, DL Boost and the processor's virtualization features to maximize performance.
