Architecture Overview
The Xeon 6548P-B uses Intel’s Granite Rapids‑D configuration, a chiplet‑based design with P‑core compute tiles, an I/O tile, and embedded accelerators, all built on the Intel 3 process.
CPU Design
It has 32 Redwood Cove P‑cores, each supporting two hardware threads via Hyper‑Threading, for 64 logical CPUs. Redwood Cove increases L1 instruction cache to 64 KB and adds wider execution resources compared to earlier Golden Cove designs, while retaining AVX‑512 and AMX support.
Memory Subsystem
The integrated memory controller supports quad‑channel DDR5 at up to 6400 MT/s, with ECC and Intel Total Memory Encryption (TME), providing high bandwidth and RAS features for server workloads.
PCIe & I/O
The CPU exposes 48 PCIe lanes: 32 Gen5 and 16 Gen4, suitable for direct‑attached NVMe, GPUs and networking. In 1S R1S‑style platforms, some UPI links are repurposed as extra PCIe Gen5 lanes to boost I/O density.
Overclocking
The multiplier is locked and there is no official support for overclocking; turbo frequencies are managed by Intel Turbo Boost 2.0 within the 195 W TDP envelope.
- Move from Intel 7 to Intel 3 process
- Addition of Intel AMX and vRAN Boost accelerators
- Higher DDR5 speed (6400 vs 5200 MT/s) and more PCIe Gen5 lanes
- Better performance‑per‑watt and consolidation vs 5‑year‑old servers
Key Highlights
- 32 P‑cores with AMX and AVX‑512 for AI and HPC
- Integrated QAT, DLB and vRAN Boost accelerators
- 48 PCIe Gen4/Gen5 lanes in a 1S platform
- Quad‑channel DDR5‑6400 with ECC and TME
- Modern Intel 3 process and Granite Rapids architecture

- 195 W TDP requires robust cooling
- 1S‑only, no dual‑socket upgrade path
- No integrated graphics
- Limited public benchmark data as of mid‑2026
- Higher platform cost than older Xeon Gold generations
History
The Xeon 6548P‑B emerged as part of Intel’s Xeon 6 6500P Granite Rapids‑SP lineup, launched in February 2025 to address mid‑range data center and edge workloads with a performance‑core‑only design on the new LGA 4710 socket. Intel positioned the 6500P series as a more mainstream counterpart to the high‑core‑count 6900P parts, emphasizing single‑socket configurations with strong AI and networking capabilities. The 6548P‑B, with its 32 P‑cores and integrated accelerators, reflects Intel’s strategy to embed domain‑specific acceleration directly into the CPU, reducing the need for separate offload cards in many virtualized, AI and RAN deployments.
Its release also marked the broader rollout of the Intel 3 process and Redwood Cove core architecture in server products, bringing improved performance‑per‑watt and RAS features versus the previous Emerald Rapids generation.

Use Cases
Interesting Facts
The 6548P‑B is one of the first Granite Rapids‑D Xeon 6 CPUs on the LGA 4710 socket, designed specifically for single‑socket servers.
Even though it has 32 cores, it lacks UPI links because it is intended only for 1S configurations; those resources are reallocated to I/O and accelerators.
Intel’s R1S platform mode repurposes UPI lanes as additional PCIe Gen5 lanes, giving some 6700P/6500P SKUs up to 136 Gen5 lanes in a single socket.
Redwood Cove P‑cores double the L1 instruction cache to 64 KB compared to earlier generations, improving instruction fetch for server workloads.
AMX on Xeon 6 can deliver up to 2x higher AI inference performance versus prior‑generation Xeons in Intel’s internal testing.
vRAN Boost in this generation can provide up to 2.4x the RAN capacity and 70% better performance‑per‑watt versus previous Xeon networking SKUs.
The CPU’s TDP is 195 W, but actual power can be lower if not all I/Os are populated, since Intel defines system TDP in worst‑case scenarios.
Maximum memory size is 1.13 TB, reflecting current DDR5 RDIMM capacities rather than a hard architectural limit.
The 6548P‑B uses a chiplet design with separate compute and I/O tiles, a departure from older monolithic Xeon die designs.
Despite being a server CPU, it includes no integrated GPU or media transcode accelerator, unlike some Xeon 6 SoC parts for network and edge.
