28-Core Xeon Gold 6258R for multi-socket servers

The Intel Xeon Gold 6258R is a 28-core server processor built on 14 nm Cascade Lake architecture. It runs at a 2.70 GHz base frequency and reaches a 4.00 GHz maximum turbo frequency. Hyper-Threading delivers 56 threads for heavy parallel workloads. The chip fits LGA 3647 sockets and carries a 205 W thermal design power.

Dual-socket scale with six memory channels

Each processor provides six memory channels supporting up to 1 TB of system memory. A 10.4 GT/s bus speed links two sockets for coherent memory access across the platform. PCI Express 3.0 lanes connect storage controllers and network adapters without a separate chipset. The 38.5 MB L3 cache reduces latency for data-intensive applications.

Virtualisation-ready with Intel Xeon features

Intel Virtualization Technology enables efficient hypervisor deployment on the 6258R. The 64-bit instruction set runs modern server operating systems and containers. Hyper-Threading and the large L3 cache improve density for virtualised database and analytics workloads. No bundled cooler is included; integrators must provide adequate cooling for the 205 W TDP.

Questions about this item

Will the 205 W TDP require a heavy-duty cooler for continuous 28-core workloads?

The processor has a 205 W thermal design power, so a server-grade heatsink or liquid loop rated for at least that heat load is necessary for sustained full-speed operation.

How loud and hot does the 205 W Xeon Gold 6258R get when running all day?

At 205 W TDP the chip will produce significant heat; noise and temperature depend entirely on the cooler and chassis airflow you pair with it.

What motherboard socket and memory channels must my system already provide for this CPU?

You need a motherboard with an LGA 3647 socket and six memory channels to use the processor.
