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.
