Overview

The Intel Xeon 8156 (CD8067303368800) is a quad-core server processor from Intel's Skylake-SP Xeon Scalable family, targeting workloads where high clock speeds and per-core performance matter more than raw thread count. With a base frequency of 3.6GHz and a max turbo of 3.70GHz, it delivers consistently fast single-threaded execution — a valuable trait for database engines, financial modeling applications, and software licensed on a per-core basis where fewer, faster cores translate to lower licensing costs.

Built for the LGA 3647 socket, the Xeon 8156 slots into Intel's Purley platform and supports multi-socket configurations, ECC memory, and enterprise RAS (Reliability, Availability, Serviceability) features expected in production server environments. The 16.5MB L3 cache helps keep frequently accessed data close to the cores, reducing memory fetch latency. At 105W TDP, it is manageable within standard server cooling designs. This processor is best suited for organizations that need proven Intel server-grade silicon with a focus on clock speed over core density.

Pros & Cons

👍 Pros

High 3.6GHz base clock delivers strong single-threaded performance for latency-sensitive server tasks
16.5MB L3 cache helps maintain throughput in data-intensive workloads
LGA 3647 socket supports multi-socket scalable server platforms
Enterprise-grade reliability with ECC memory support and RAS features
Relatively modest 105W TDP for a server-class processor

👎 Cons

Only four cores, which limits heavily multi-threaded workload performance compared to higher-core-count Xeon SKUs
Very narrow turbo boost headroom — only 100MHz above the base clock
Premium Xeon 8100 series pricing for a quad-core part
Requires an LGA 3647 motherboard, which limits platform choices and increases overall build cost

Frequently Asked Questions

What socket does the Intel Xeon 8156 use?

The Xeon 8156 uses Socket 3647 (LGA 3647), which is designed for Intel's Scalable Processor platform and requires a compatible server or workstation motherboard.

What is the thermal design power (TDP) of this processor?

The TDP is 105W, so you will need adequate cooling in your server chassis — either a compatible heatsink or liquid cooling solution rated for that thermal envelope.

How much cache does the Xeon 8156 have?

It features 16.5MB of L3 cache, which helps reduce memory latency for data-intensive server applications.

Is this processor suitable for multi-socket configurations?

Yes, the Xeon Scalable 8100 series supports multi-socket server platforms, allowing you to pair multiple processors for increased compute capacity.

What is the difference between the base and turbo frequencies?

The base frequency is 3.6GHz and the max turbo frequency is 3.70GHz, meaning this chip is optimized for sustained high-clock performance rather than large turbo bursts.
