Intel Xeon 634 12-core server processor

The Xeon 634 is a twelve-core, twenty-four-thread server CPU built on Intel 3 process technology. It targets single-socket platforms that need balanced compute density and memory bandwidth. The part operates at a 2.7 GHz base frequency with turbo peaks up to 4.6 GHz. Buyers who need dual-socket scalability or higher core counts should look elsewhere.

LGA 4710 socket and DDR5-6400 quad-channel limits

This processor fits only the LGA 4710 socket and supports DDR5 memory at 6400 MHz across four channels, to a maximum capacity of 2 TB. It provides eighty PCI Express 5.0 lanes for I/O expansion. Systems built on other socket types or memory generations cannot use this CPU.

150 W thermal design power

The chip carries a 150 W base TDP and a 180 W maximum turbo power rating. Cooling solutions and power delivery must be sized for these values. Deployments constrained by lower power envelopes or limited airflow will need a different processor.

Questions about this item

Which Xeon 634 capacity or version should I choose for a single-socket server?

This Xeon 634 is a single 12-core model with 24 threads, 48MB L3 cache and a 150W TDP, designed for 1S-only scalability.

What does the 2.7 GHz base clock mean once the CPU is installed in a real server?

The processor runs at 2.7 GHz under sustained load and can reach 4.6 GHz via Turbo Boost Max 3.0 or 4.4 GHz with Turbo Boost 2.0 when thermals allow.

What does the PCIe 5.0 interface cap in practice on this Xeon 634?

The chip provides up to 80 PCIe 5.0 lanes for high-speed storage, networking and accelerator cards in a single-socket platform.
