12-core Xeon Gold server processor

This 12-core Intel Xeon Gold processor runs at 2.6 GHz with a 3.70 GHz maximum turbo frequency. It uses the LGA 3647 socket and is built on 14 nm technology. The thermal design power is 125 W with a maximum operating temperature of 86 °C.

Suited for multi-threaded server workloads

The 12 cores and 19.25 MB L3 cache handle virtualisation, database and compute tasks in dual-socket systems. Buyers needing higher core counts or lower power envelopes should consider other models. Single-threaded applications will not use the full core count.

Socket 3647 compatibility requirement

This processor only fits motherboards with the LGA 3647 socket and matching chipset support. Verify the platform qualification list before purchase. An incompatible board will prevent installation.

Questions about this item

How much heat does the 125W TDP processor produce under sustained load?

The Xeon Gold 6126T has a 125W thermal design power and a maximum operating temperature of 86°C, so sustained workloads will require a cooler rated for at least 125W dissipation.

Does this CPU need a Socket 3647 motherboard to function?

Yes, the 6126T installs only in an LGA 3647 socket, so the motherboard must provide that specific socket and a compatible server chipset.

Can the 6126T reach 3.70 GHz on all 12 cores simultaneously?

The 3.70 GHz figure is the maximum turbo frequency; actual all-core speed depends on the motherboard power delivery and cooling, and will typically stay below the single-core peak.
