CPU Comparison
Intel Xeon 6776P-B vs Intel Xeon 6788P
A side-by-side comparison of specs, performance and value. The Intel Xeon 6776P-B is a 72-core, 144-thread server processor based on the Granite Rapids-D platform, designed for single-socket edge, telecom, and networking systems with integrated I/O and accelerators such as vRAN Boost, AMX, and QAT.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Strong multi-threaded integer and throughput performance for server and telco workloads, but optimized for data-plane rather than interactive productivity.
Outstanding multi-threaded throughput for virtualized and database workloads, especially with AMX and 8-channel memory.
Gaming
Not designed for gaming; low single-thread focus and no integrated graphics make it a poor choice compared to client CPUs.
Not targeted at gaming; high latency and core count prioritize throughput over single-threaded gaming performance.
Virtualization
Excellent for NFV and containerized telco/VNFs, with high core count and memory bandwidth, though single-socket only.
Excellent VM density and per-VM performance thanks to 86 cores, large cache, and RAS features.
Efficiency
325 W TDP for 72 cores yields good throughput per watt for its class, but newer competing edge CPUs can deliver better performance per watt and per dollar in some scenarios.
High performance per socket but high power draw; efficiency depends heavily on workload consolidation.

General Server
- AMD EPYC 8635PAlt
Higher core count (84 vs 72), lower TDP (225 W), and better performance per watt and per dollar in some SPEC benchmarks; strong alternative for vRAN and edge.
- Intel Xeon 6776P (LGA4710)Alt
Same core count and similar clocks but in an LGA socket for dual-socket servers; choose if you need 2S configurations or standard board upgradeability.
- Intel Xeon 6768P-B (64-core, Granite Rapids-D)Alt
Lower core count and slightly lower TDP in the same BGA5026 platform; better fit when 72 cores are overkill.
- Intel Xeon 6774P (LGA4710)Alt
64-core Granite Rapids-SP part with higher all-core turbo and 2S support; good if you prefer a socketed platform and can accept fewer cores.
- NVIDIA Grace CPU SuperchipAlt
Non-x86 but very high core count and memory bandwidth; attractive for greenfield edge/AI stacks that can adopt Arm software.

Our Verdict on Each
A powerful, highly integrated edge SoC with strong multi-threaded throughput and purpose-built accelerators for telco and networking, but its high TDP and single-socket focus limit deployment flexibility compared to newer or more efficient alternatives.
Best for: Building single-socket edge servers for 5G vRAN, RAN, or network appliances where you want Intel x86 with integrated accelerators and high core density.
Read the full reviewA no-compromise, high-core-count Xeon for enterprises that need maximum per-socket density and strong AI acceleration, but its 350 W TDP and premium pricing demand a careful TCO analysis.
Best for: 2S/4S/8S servers or high-end workstations running large in-memory databases, dense virtualization, or CPU-based AI inference where per-socket core count and memory bandwidth are critical.
