Specifications
Performance
In server workloads such as databases, analytics, and batch jobs, the 48 cores and 96 threads deliver high throughput; exact scores depend on platform configuration.
Strong for multi‑tenant VMs and containers thanks to high core count, large caches, and eight‑channel memory.
No iGPU; gaming is not a target use case for this server part.
At 330 W for 48 cores, the 6747P targets performance over efficiency; Intel SST‑PP profiles let operators tune the power/performance trade‑off.
- •No integrated graphics
- •Socket and platform are server/workstation oriented, not desktop gaming
- •Single‑thread clocks are lower than typical gaming CPUs; latency matters more for servers
- •Intel AMX and DL Boost accelerate matrix and inference workloads on‑CPU
- •No discrete GPU on the CPU; large AI training workloads typically require add‑in accelerators
- •Well‑suited for inference at scale in data centers with CPU‑first deployments

History
The Xeon 6747P is part of the Granite Rapids‑SP (Xeon 6 6700P) family announced by Intel to re‑architect its data center lineup around chiplet designs and the Intel 3 process. Launching in Q1 2025, it targets dual‑socket servers with high core counts, large caches, and modern I/O. Compared with prior Xeon Scalable generations, Granite Rapids‑SP doubles down on per‑socket memory bandwidth (eight channels with MRDIMM support) and PCIe 5.
0 density (up to 88 lanes), while adding built‑in accelerators such as AMX, DSA, DLB, IAA, and QAT. Intel also introduced Speed Select profiles that let OEMs and cloud operators quickly switch between throughput‑optimized and per‑core performance‑optimized operating points within the same 330 W envelope. These changes reflect an industry trend toward workload‑specific tuning and confidential computing in large‑scale data centers.
Improvements over Previous Generation

Use Cases
Interesting Facts
Granite Rapids‑SP uses a chiplet design with separate compute and I/O tiles, supporting Intel 3 compute tiles with up to two compute tiles on LGA 4710 and up to three on LGA 7529 (6900P).
The 6747P offers two SST‑PP profiles within 330 W: a 2.7 GHz “Server Mode” and a 3.1 GHz “Compute Mode,” giving operators a simple switch between efficiency‑ and performance‑biased tuning.
MRDIMM support at 8800 MT/s significantly raises effective memory bandwidth versus standard DDR5, which benefits memory‑bound workloads.
Intel includes multiple accelerators on‑chip: DSA, DLB, IAA, QAT, and AMX, reducing load on the CPU cores for targeted workloads.
The 88 PCIe 5.0 lanes per socket allow dense NVMe, 100/200 GbE NICs, and accelerator cards without a PCIe switch in many configurations.
