The Intel Xeon 6716P-B is a 40-core, 80-thread server/edge processor based on the Granite Rapids-D (Xeon 6 SoC) platform, designed for single-socket systems with integrated networking and acceleration for vRAN, security, and edge AI workloads.
The Intel Xeon 6716P-B is a 40-core, 80-thread Granite Rapids-D processor on Intel’s Xeon 6 SoC platform. It runs at 2.5 GHz base and 3.
5 GHz turbo, with 160 MB of L3 cache, four channels of DDR5-6400, and 48 PCIe lanes (Gen 4/5) in a single-socket BGA4368 package. Designed for edge and telecom use, it integrates Intel vRAN Boost, QuickAssist Technology (QAT), Dynamic Load Balancer (DLB), and Data Streaming Accelerator (DSA), along with AVX-512 and AMX for AI workloads. Its 235 W TDP and soldered design favor tightly integrated appliances rather than general-purpose servers or workstations.
Specifications
Performance
Strong multi-threaded performance for edge and control-plane workloads, with good single-threaded capability for latency-sensitive tasks.
Capable for NFV and lightweight VMs at the edge, but memory capacity and single-socket limits restrict large-scale consolidation compared to bigger Xeon 6 SKUs.
Not targeted at gaming; lacks integrated graphics and is optimized for server/edge workloads rather than high-refresh-rate or low-latency gaming scenarios.
235 W TDP is high for a 40-core edge SoC; AMD EPYC 8005 competitors offer more cores at similar or lower power, which hurts efficiency in strictly power-constrained deployments.
- •No integrated graphics; not intended for gaming
- •Server-optimized I/O and power management
- •Gamers should choose mainstream desktop or workstation CPUs instead
- •AMX and AVX-512 provide strong CPU-based AI inference for edge models
- •No dedicated NPU or GPU; for large models, pair with discrete accelerators
- •Well suited for small to medium batch inference at the edge

History
The Xeon 6716P-B emerges from Intel’s effort to unify its data center and edge product lines under the Xeon 6 brand, with Granite Rapids-D serving as the SoC-optimized variant for networking and industrial deployments. Announced in early 2025 alongside other Granite Rapids-D SKUs, it targets the gap between older Xeon D parts and higher-core-count Granite Rapids-SP server chips, bringing P-cores, DDR5, PCIe 5.0, and integrated vRAN/QAT acceleration to a single-socket BGA package.
This makes it a natural fit for OEMs building 5G vRAN appliances, secure gateways, and dense edge servers, where vibration resistance and integrated I/O matter more than socket flexibility. Compared to earlier Xeon D designs, it dramatically increases core count and cache, while adding AI-oriented features like AMX and stronger AVX-512 support, reflecting the growing importance of edge AI and unified telecom compute platforms.
Improvements over Previous Generation
- Move from Xeon D (Brigade) to Xeon 6 Granite Rapids-D with P-cores

Use Cases
Interesting Facts
Granite Rapids-D is Intel’s first Xeon 6 SoC family explicitly branded for network and edge, with up to 42 cores demonstrated at Hot Chips 2024.
Each Redwood Cove P-core in Granite Rapids includes a dedicated 2 MB L2 cache, giving the 6716P-B an estimated 80 MB of L2 alongside 160 MB of shared L3.
Xeon 6 SoC platforms integrate accelerators like vRAN Boost, QAT, DLB, and DSA that were previously on separate PCIe cards or eASICs.
The 6716P-B uses a chiplet design with Intel 3 compute tiles and an Intel 4 I/O tile connected via EMIB, yet is presented as a monolithic SoC to software.
Despite being an edge SoC, it supports up to 1.13 TB of DDR5-6400 ECC memory, far exceeding typical embedded constraints.
Intel positions Xeon 6 SoC as a successor to both Xeon D and some lower-power Xeon Scalable parts in telco and edge.
SPEC CPU2017 results for systems using Xeon 6716P-B show strong floating-point throughput for a single-socket edge CPU.
Compared to AMD’s EPYC 8005 84-core 225 W SKUs, the 6716P-B has fewer cores but similar TDP, reflecting different design choices for edge compute.
The 6716P-B’s BGA4368 package is also used by other Granite Rapids-D SKUs like the Xeon 6706P-B, enabling a common platform design for OEMs.
Intel’s vRAN Boost on this SoC can replace external ACC100-style accelerators for 5G vRAN, simplifying board designs.

It can run VMs and containers at the edge, but its single-socket and moderate memory capacity make it better suited for lightweight NFV and control-plane workloads rather than large-scale consolidation.
What OSes support Xeon 6716P-B?
Modern server OSes with Xeon 6 support (Windows Server, major Linux distributions, VMware ESXi) are expected to work; always verify with your OS vendor for specific platform support.
Can I upgrade from Xeon D to Xeon 6716P-B?
Only if your platform is designed for the FCBGA4368 Xeon 6 SoC; Xeon D and Xeon 6 SoC have different sockets and pinouts, so a drop-in upgrade is not possible.
