16-core Xeon Gold 6226R for scalable servers

The Intel Xeon Gold 6226R is a 16-core server processor with 32 threads built on 14 nm Cascade Lake architecture. It operates at a 2.9 GHz base frequency and reaches a 3.90 GHz maximum turbo frequency. Designed for multi-socket data centre platforms, it supports up to four-socket scalability for mainstream compute, cloud, network and storage workloads.

LGA 3647 socket with six-channel DDR4 and 48 PCIe

This CPU installs in an LGA 3647 socket and provides an integrated memory controller running DDR4 at 2933 MT/s across six channels. It exposes 48 PCI Express 3.0 lanes for high-speed I/O and accelerator cards. A 150 W thermal design power requires server-grade cooling and a power delivery system rated for that envelope.

22 MB L3 cache with virtualization

The 22 MB L3 cache reduces latency for heavily threaded applications. Intel Virtualization Technology support enables efficient VM density, while hardware-enhanced security features help protect data across multi-tenant environments. No bundled accessories or software are included with the tray processor.

Questions about this item

How does the 150W thermal design power limit sustained performance?

The 150W TDP sets the cooling requirement; under continuous full-core load the processor will throttle to stay within this power envelope unless the system cooler can dissipate more heat.

What noise and heat should I expect when all 16 cores run at 2.9 GHz all day?

At base frequency the chip draws up to 150W, so a server-grade heatsink or liquid loop is needed; fan noise will match the cooler’s capacity to move that heat continuously.

Which motherboard socket and memory kit must I already have for this Xeon Gold 6226R?

You need an LGA 3647 motherboard with six-channel DDR4 2933 support and a power delivery system rated for at least 150W.
