86-core Xeon 6 server processor

The Intel Xeon 6 6788P delivers 86 cores and 172 threads at a 2.0 GHz base frequency. Maximum turbo reaches 3.8 GHz while all-core turbo sustains 3.2 GHz. Built on 3 nm process technology with 336 MB L3 cache, it targets dense virtualisation, high-performance computing and large-scale database workloads.

FCLGA 4710 platform requirements

This processor requires a motherboard with the FCLGA 4710 socket and a chipset supporting the Xeon 6 series. The integrated memory controller runs DDR5 at 6400 MT/s across eight channels for up to 4 TB capacity. PCI Express 5.0 provides 88 lanes for accelerators, storage and networking. A cooling solution rated for 350 W TDP must be sourced separately.

Processor-only package with UPI links

The box contains the processor only; no heatsink or fan is included. Four Intel UPI links operating at 24 GT/s enable eight-socket scalability for expanded core counts and memory capacity. Instruction-set extensions include AMX, AVX-512, AVX2, AVX and SSE4.2 for accelerated AI inference, analytics and vector workloads.

Questions about this item

Does the Intel Xeon 6 6788P processor include a cooling solution in the box?

No, the processor is sold as processor only and a cooling device is not included; a compatible FCLGA 4710 cooler rated for 350 W TDP must be purchased separately.

Should I choose the 86-core 2.0 GHz model or a different Xeon 6 SKU for my workload?

The 86-core 6788P delivers 172 threads, 336 MB L3 cache, 8-channel DDR5-6400 support up to 4 TB, and all-core turbo of 3.2 GHz; select it when you need maximum core density and memory bandwidth in a single socket.

What does the 3.8 GHz max turbo frequency mean once the CPU is installed in a server?

One or two cores can briefly reach 3.8 GHz under light load, while sustained all-core workloads run at 3.2 GHz across all 86 cores, giving predictable throughput for heavily threaded applications.
