Networking and edge SoC
- AMD EPYC 8324PAlt
Lower TDP range (155–225 W) and SP6 platform with similar edge/telco focus; good alternative where power efficiency matters more than integrated accelerators.
Same Granite Rapids-D family with slightly higher clocks (2.6 GHz base, 4 GHz turbo) and same core count if you need more frequency headroom.
Compare head-to-head- Intel Xeon D-2899NTAlt
Lower power (135 W) and mature platform if you don’t need DDR5, PCIe 5.0 or the latest accelerators.
- Intel Xeon 6546P-B (32-core, 195 W)Alt
Lower core count and TDP for less demanding edge workloads while staying in the same Granite Rapids-D ecosystem.
- AMD EPYC 8434PAlt
Higher core count (48) with similar telco/edge focus if you need more threads and can accommodate a slightly higher TDP.

Very similar Granite Rapids-D SoC if you need a slightly different feature or availability profile.
Compare head-to-head- Intel Xeon Gold 6430Alt
Better for general dual-socket enterprise servers where edge accelerators are not required.
- AMD EPYC 9455 (48-core, 300 W)Alt
Higher core count and memory bandwidth for more traditional server workloads.
- Older Xeon D-2789NTAlt
Lower TDP, simpler edge/NFV use cases where 40 P-cores and heavy acceleration are overkill.
Our Verdict on Each
A highly integrated edge SoC that brings strong multi-threaded performance and dedicated accelerators for networking and AI workloads, but with high power and a niche platform that limits broader reuse.
Best for: Building or specifying 5G vRAN, edge AI or network security appliances where integrated accelerators and high core count reduce total system complexity.
Read the full reviewA very capable edge-optimized Xeon with strong integrated acceleration and I/O for telecom and industrial workloads, but its high TDP and BGA soldering limit flexibility and DIY appeal.
Best for: OEM or integrator building dense, vibration-resistant edge or telecom appliances that can leverage vRAN Boost and QAT in a single-socket BGA platform.
