Server CPU for single-socket deployments

The Intel Xeon 6511P is a 16-core server processor built for single-socket platforms. It delivers 32 threads through Hyper-Threading and runs at a 2.3 GHz base frequency. The chip targets workloads that fit within one socket and need balanced compute density.

PCIe 5.0 lane budget and memory ceiling

The processor exposes 136 lanes of PCI Express 5.0 for high-speed storage and networking cards. Its integrated controller supports DDR5 6400 across eight channels up to a 4 TB maximum capacity. Scalability is limited to one socket, so multi-node expansion requires separate systems.

150 W thermal design power

A 150 W TDP defines the cooling requirement for this FCLGA 4710 package. No cooling device is included, so a compatible heatsink or liquid loop must be sourced separately. The 3 nm Granite Rapids die reaches a 4.2 GHz maximum turbo and a 4.1 GHz all-core turbo within this envelope.

Questions about this item

Should I choose the 16-core 6511P or a higher-core-count Xeon 6 for my single-socket server?

The 6511P delivers 16 cores and 32 threads at a 2.3 GHz base with 4.1 GHz all-core turbo in a 150 W envelope. It is rated for 1S only, so it fits single-socket boards that need high per-core speed and 72 MB L3 without the cost of larger core counts.

What does the 4.2 GHz max turbo frequency mean once the processor is installed in a real machine?

One core can reach 4.2 GHz for short bursts when power and thermal headroom allow. Sustained all-core workloads run at 4.1 GHz across all 16 cores. Actual clocks depend on your cooler, chassis airflow and BIOS power limits.

What does the PCI Express 5.0 interface with 136 lanes cap in practice?

The CPU exposes 136 lanes of PCIe 5.0, enabling up to 136 x1 devices or fewer wider slots at full 5.0 speed. Total bandwidth scales with lane allocation; the cap is the lane count, not the revision.
