Our Verdict on Each
An extremely capable dual‑socket server CPU with best‑in‑class core count and memory bandwidth for its generation, best suited for organizations that can utilize its 120 cores and 12 memory channels rather than treating it as a general‑purpose compute node.
Best for: Dual‑socket servers running memory‑intensive, highly parallel workloads such as large in‑memory databases, virtualization, or HPC where core count and memory bandwidth are the primary bottlenecks.
Read the full reviewA powerhouse for multi-threaded server workloads with massive core counts and AI accelerators, but its 500W TDP and platform requirements demand careful system design.
Best for: New data center servers for AI, HPC, or high-density virtualization with appropriate cooling and power infrastructure.
