Market
Server / Edge / Network
The Intel Xeon 6544P-B is a 32-core, 64-thread server and edge SoC processor from Intel’s Xeon 6 Granite Rapids-D family, built on the Intel 3 process and targeting network, edge, and communications workloads with integrated accelerators, DDR5 memory, and 48 PCIe 5.0 lanes.
Intel’s Xeon 6544P-B sits in the middle of the Granite Rapids-D Xeon 6 SoC lineup, offering 32 Redwood Cove P-cores and 64 threads at 170 W TDP. It supports up to 1.13 TB of DDR5-5600 across four channels and provides 48 PCIe lanes (32 Gen5, 16 Gen4), making it suitable for high-throughput edge and networking appliances.
Integrated accelerators like Intel QAT, DLB, DSA, and a media transcode engine differentiate it from generic server CPUs, targeting vRAN, edge AI, and video workloads. Compared to higher-core Granite Rapids-D parts, the 6544P-B trades core count for lower power and cost, and it is not intended for dual-socket platforms.
Specifications
Performance
No independent benchmark scores available for this SKU; expected to perform well in server-style integer and crypto workloads due to high core count and integrated accelerators.
Designed for lightweight edge virtualization and containerized workloads; no public benchmarks yet.
Not applicable; this is a server/edge SoC without integrated graphics and is not intended for gaming workloads.
170 W TDP for 32 P-cores is competitive within the Granite Rapids-D lineup, but real efficiency depends heavily on accelerator utilization and power management at the system level.

Architecture Overview
Granite Rapids-D is the edge-optimized variant of Intel’s 6th-gen Xeon Scalable platform, focusing on high integration and accelerator-rich SoC designs rather than maximum core count. It uses Redwood Cove P-cores built on Intel 3 and connects them via a mesh to integrated I/O and accelerator tiles.
CPU Design
32 Redwood Cove performance cores with Hyper-Threading yield 64 threads. Each core has a private L2 cache (expected 2 MB per core based on Granite Rapids architecture) and shares a 128 MB L3 slice across the mesh.
Memory Subsystem
Quad-channel DDR5-5600 memory controller supports up to 1.13 TB with ECC, optimized for high bandwidth and RAS in edge and communications environments.
PCIe & I/O
48 PCIe lanes from the CPU: 32 Gen5 and 16 Gen4, enabling direct attach of high-speed NICs, accelerators, and NVMe storage without a separate PCH.
Overclocking
The multiplier is locked; turbo behavior is managed by Intel Turbo Boost 2.0 within the 170 W TDP envelope. No traditional overclocking is supported.
- Move from Ice Lake/Broadwell-DE to Redwood Cove P-cores with higher IPC and AVX-512/AMX
- DDR5 instead of DDR4, with higher bandwidth and capacity
- Integrated accelerators (QAT, DLB, DSA, media transcode) previously external or absent
- PCIe 5.0 support alongside PCIe 4.0
Key Highlights
- 32 high-performance Redwood Cove P-cores with strong per-thread throughput
- Integrated QAT, DLB, DSA, and media transcode accelerators for vRAN and media
- 48 PCIe 5.0/4.0 lanes for high-speed NICs and accelerators
- Quad-channel DDR5-5600 with ECC and up to 1.13 TB capacity
- Single-socket SoC design reduces platform complexity for edge systems
- No dual-socket support; limited to 1S platforms
- No integrated graphics; GPU or display outputs require a discrete card
- 170 W TDP can still be challenging in tightly sealed edge enclosures
- L2 cache and per-core cache breakdown not fully documented by Intel
- New platform with limited independent benchmark data
History
The Xeon 6544P-B emerged from Intel’s Granite Rapids-D program, which itself is part of the broader 6th-generation Xeon Scalable family launched in 2024–2025. Granite Rapids-D was conceived as an edge- and network-focused counterpart to the data center Granite Rapids-SP/AP parts, integrating more I/O and accelerators on-die to reduce component count in communications and edge servers. Intel marketed this SoC lineup as a way to consolidate vRAN, security, and media processing onto a single chip, replacing older Xeon D and Sapphire Rapids-EE designs.
Within that stack, the 6544P-B occupies a mid-range position: 32 P-cores and 170 W TDP balance compute density against power, making it suitable for high-throughput but thermally constrained edge nodes. Its release in late 2025 coincided with growing industry demand for integrated edge SoCs that could handle 5G, media, and AI workloads without requiring large, power-hungry dual-socket servers.
Improvements over Previous Generation
- Move from Ice Lake/Broadwell-DE to Redwood Cove P-cores with higher IPC and AVX-512/AMX
- DDR5 instead of DDR4, with higher bandwidth and capacity
- Integrated accelerators (QAT, DLB, DSA, media transcode) previously external or absent
- PCIe 5.0 support alongside PCIe 4.0
Alternatives & Competitors
Should You Buy It?
Recommended for the right buyer
Building a single-socket edge or network appliance where you can exploit the integrated accelerators and high PCIe lane count, such as vRAN, secure gateways, or media edge servers.
Avoid if…
- You need dual-socket scalability
- Your workload is purely generic compute with no accelerator usage
- You want maximum core density and can tolerate higher TDP
- You are building a general-purpose data center server rather than an edge appliance
