Processor Intel Xeon Gold 6246 3,3 GHz 12 cores 24,75 MB LGA 3647

Processor Intel Xeon Gold 6246 operates at a base frequency of 3.3 GHz and features 12 physical cores with 24.75 MB of last-level cache. Built on the Cascade Lake microarchitecture for the LGA 3647 (Socket P) platform, this server-class CPU supports hexa-channel DDR4 memory up to a maximum internal capacity of 1.02 TB and includes advanced instruction set support such as SSE4.2, AVX, AVX2 and AVX-512 for high-performance and virtualization workloads.

Advantages

The Intel Xeon Gold 6246 provides hardware features that improve performance, security and manageability for server and workstation environments. It supports Intel Turbo Boost and Turbo Boost Max technologies to raise single-core frequencies when needed, Hyper-Threading for increased parallelism, and a large shared cache (Intel Smart Cache) to reduce memory latency. Built-in virtualization and security extensions such as VT-x, VT-d, EPT, Intel AES-NI, Execute Disable Bit and Intel Run Sure Technology enhance isolation, encryption acceleration and platform reliability.
