CPU Comparison
Intel Xeon 6747P vs Intel Xeon 6756P-B
A side-by-side comparison of specs, performance and value. The Intel Xeon 6747P is a 48-core, 96-thread server processor in the Xeon 6 6700P series (Granite Rapids-SP) built on the Intel 3 process with 288 MB of L3 cache, DDR5/MRDIMM support, 88 PCIe 5.0 lanes, and a 330 W base TDP, designed for dual-socket data center and HPC workloads.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
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.
Outstanding multi-threaded performance for server productivity workloads such as databases, virtualization, and analytics thanks to 64 P-cores and 8-channel DDR5.
Gaming
No iGPU; gaming is not a target use case for this server part.
Not intended for gaming; lacks integrated graphics and is optimized for server workloads rather than low-latency game loops.
Virtualization
Strong for multi‑tenant VMs and containers thanks to high core count, large caches, and eight‑channel memory.
Excellent for large VM counts and VDI deployments, with high core count, ample memory bandwidth, and hardware virtualization features (VT-x, VT-d, EPT).
Efficiency
At 330 W for 48 cores, the 6747P targets performance over efficiency; Intel SST‑PP profiles let operators tune the power/performance trade‑off.
High absolute performance per watt, but 325 W TDP and server platform overhead mean overall efficiency is more about consolidation than low power.
Specialized Performance
AI / ML
- 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
- AMX provides hardware acceleration for INT8 and BF16/FP16 matrix operations.
- Well suited for CPU-based AI inference and prototyping where GPUs are not available.
- MLPerf results for Xeon 6 P-core family show ~1.9x AI inference gains vs 5th Gen Xeon, though not specific to this SKU.
Content Creation
Gaming
- 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
- No integrated graphics; requires a discrete GPU.
- Server-optimized for throughput, not gaming latency or refresh rates.
- Not a target use case for this CPU.
