CPU Comparison
Intel Xeon 6737P vs Intel Xeon 6756P-B
A side-by-side comparison of specs, performance and value. The Intel Xeon 6737P is a 32-core, 64-thread server processor based on the Granite Rapids-SP architecture, offering 2.9 GHz base and 4 GHz turbo clocks, 144 MB of L3 cache, eight-channel DDR5-6400 memory, and 88 PCIe 5.0 lanes in a 270 W TDP envelope for dual-socket platforms.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
SPEC CPU2017 results exist for Xeon 6737P platforms but are server-focused; generic productivity scores are not meaningful.
Outstanding multi-threaded performance for server productivity workloads such as databases, virtualization, and analytics thanks to 64 P-cores and 8-channel DDR5.
Gaming
Not intended for gaming; no relevant gaming benchmarks for this server SKU.
Not intended for gaming; lacks integrated graphics and is optimized for server workloads rather than low-latency game loops.
Virtualization
Strong VM density expected based on 32 cores, 64 threads, and 4 TB memory capacity, but no standardized virtualization score can be claimed without official benchmarks.
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
270 W TDP is high for a 32-core server CPU; efficiency is competitive only within the Xeon 6 P-core family and versus prior Xeon generations, not versus low-power SKUs.
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 with BF16/INT8 support accelerates deep learning inference
- Two AVX-512 FMA units per core benefit vectorized AI and HPC kernels
- No dedicated AI accelerator; heavy AI training still better suited to GPUs
- 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
- Server processor not targeted at gaming
- No integrated graphics
- No official gaming benchmarks
- 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.

Our Verdict on Each
A strong Xeon 6 P-core SKU for two-socket servers that need high per-core performance, AMX acceleration, and plenty of PCIe 5.0 connectivity, though its 270 W TDP and platform cost demand careful power and cooling planning.
Best for: Dual-socket servers running virtualization, in-memory databases, or mixed AI/HPC workloads that can leverage AMX and high PCIe 5.0 lane counts.
Read the full reviewA very high-core-count server CPU with strong AI acceleration and massive memory bandwidth, best suited for single-socket consolidation and AI workloads where its power and cost can be justified.
Best for: Single-socket server for AI inference, virtualization, or in-memory databases where 64 cores and 8-channel DDR5 provide a consolidation upgrade over older multi-socket systems.
