Processor Intel Xeon Gold 6254 3,1 GHz 18 cores 24,75 MB LGA 3647

The Intel Xeon Gold 6254 is a server-class processor with 18 cores, a base frequency of 3.1 GHz and 24.75 MB of last-level cache. Built on Intel Cascade Lake microarchitecture for the LGA 3647 socket, this CPU supports hexa-channel DDR4 memory up to 1.02 TB, advanced SIMD and vector instruction sets including SSE4.2, AVX, AVX2 and AVX-512, and is scalable for multi-socket (up to 4S) server platforms. It is intended for demanding server and workstation workloads that require high core counts, large memory capacity and enterprise-grade platform features.

Advantages

The processor offers high parallel compute capacity with 18 physical cores and Intel Hyper-Threading support, a substantial 24.75 MB Intel Smart Cache accessible across cores, and Turbo Boost features that increase single-threaded performance up to 4.0 GHz when thermal and power headroom allow. Built-in enterprise technologies such as Intel AES-NI, Intel VT-x/VT-d with EPT, Intel RDT, Intel Run Sure and support for Intel Optane persistent memory enhance security, virtualization performance and platform reliability.

Suitable for

• Virtualization hosts and hyper-converged infrastructure
• Database servers and in-memory analytics
