Intel CD8069504194501 Xeon Gold 6254 18-Core CPU

Name: Intel CD8069504194501 Xeon Gold 6254 18-Core CPU
Brand: Intel
SKU: CD8069504194501

Overview

The Intel Xeon Gold 6254 is an 18-core, 36-thread server processor built on the Cascade Lake microarchitecture, operating at a 3.10GHz base frequency with a 4.00GHz single-core turbo ceiling. Its 24.75MB of L3 cache supports the data locality demands of database, analytics, and virtualization workloads where cache miss latency is a primary bottleneck. The 200W TDP is high by modern standards but reflects the processor's design priority: sustained all-core frequency under demanding server loads rather than efficiency-optimized idle behavior. It occupies Intel's Socket 3647 LGA platform, supporting dual-socket server configurations that can scale to 36 physical cores per system.

This processor is built for data center and enterprise server deployments — specifically workloads that require high per-core frequency alongside significant thread count: transactional databases, enterprise ERP systems, large-scale virtualization hosts, and memory-bandwidth-intensive HPC tasks. It is not a cloud-native efficiency chip; it is a high-frequency, high-TDP workhorse for on-premises infrastructure where raw compute throughput per socket matters more than joules per operation. Organizations maintaining existing Cascade Lake infrastructure will find the 6254 slots cleanly into current rack configurations. For new deployments, the platform's age relative to Ice Lake and Sapphire Rapids Xeon generations is worth evaluating against power and cooling cost projections.

Pros & Cons

👍 Pros

18 cores and 24.75MB L3 cache provide substantial compute density for parallel server workloads — database query processing, virtualization, and scientific computing
4.00GHz max turbo frequency gives strong single-threaded burst performance despite the high core count
Socket 3647 enables dual-socket configurations, effectively doubling core count to 36 in two-processor server builds
Cascade Lake architecture includes hardware mitigations for Spectre/Meltdown, reducing the performance overhead of software-only patches compared to earlier Xeon generations

👎 Cons

200W TDP demands robust server-grade cooling infrastructure — not suitable for space-constrained or passively cooled chassis
Socket 3647 is specific to the Cascade Lake/Skylake-SP server platform, which has been succeeded by newer Xeon generations offering better perf-per-watt ratios
High core count with 200W TDP translates to significant data center power and cooling costs at scale compared to more recent Ice Lake or Sapphire Rapids Xeon generations

Frequently Asked Questions

What socket does the Xeon Gold 6254 use, and which server platforms support it?

The 6254 uses Intel Socket 3647 (LGA 3647), compatible with Intel Scalable Platform servers based on the Cascade Lake architecture — including dual-socket configurations. It is not compatible with consumer desktop motherboards.

What does the 200W TDP mean for server cooling requirements?

A 200W TDP requires active server-grade cooling — standard rack server heatsinks rated for high-TDP Xeon processors, or liquid cooling solutions in dense deployments. This is not a processor suited to passive or low-airflow chassis; thermal management directly impacts sustained turbo performance.

How many memory channels does the 6254 support, and what is the maximum memory capacity?

The Xeon Gold 6254 supports Intel's multi-channel DDR4 memory architecture on the Cascade Lake platform. Exact channel count and maximum memory capacity depend on the specific motherboard implementation, but the platform typically supports six memory channels per socket with substantial LRDIMM/RDIMM capacity.

Is the Xeon Gold 6254 suitable for virtualization workloads?

Yes — the 6254 supports Intel Virtualization Technology (VT-x and VT-d) and is well-suited to hypervisor environments running multiple concurrent VMs. Its 18 cores and 24.75MB L3 cache provide substantial compute resources for multi-tenant virtualization.

What is the difference between the 3.10GHz base frequency and the 4.00GHz max turbo frequency?

The 3.10GHz base is the guaranteed sustained clock speed across all 18 cores under full load within the 200W TDP envelope. The 4.00GHz turbo frequency is the single-core peak achievable when thermal and power headroom allow — typical in lightly threaded workloads or burst scenarios.
