Processor Intel Xeon Gold 6348 2.6 GHz 42 MB LGA 4189

The Intel Xeon Gold 6348 is a server-class processor operating at a base frequency of 2.6 GHz with a 42 MB cache and LGA 4189 socket compatibility. Built on the Ice Lake microarchitecture, the 28-core CPU supports octa-channel DDR4 memory configurations up to 6.14 TB and includes advanced instruction set extensions such as SSE4.2, AVX, AVX2 and AVX-512. The processor integrates security and virtualization technologies including Intel SGX (maximum enclave size 64 GB), Intel VT-x/VT-d, AES-NI and hardware acceleration features to improve cryptographic, AI inference and I/O performance for enterprise workloads.

Advantages

This processor offers high core density and a large shared cache for demanding multi-threaded server workloads, combined with broad hardware support for virtualization and security. Features like Intel Turbo Boost, Intel Hyper-Threading, AVX-512 with FMA units and Intel DL Boost increase performance for compute-intensive and AI inference tasks, while Intel Crypto Acceleration and AES-NI reduce encryption overhead. Octa-channel memory support and Intel Optane persistent memory compatibility enable large memory capacities and improved memory-bound application performance.
