Intel has published detailed turbo frequency specifications for its new Granite Rapids-WS Xeon 600 Series workstation processors, revealing significant performance trade-offs under heavy workloads. The flagship Xeon 698X features 86 cores and 172 threads with 336 MB of L3 cache, offering a 2.0 GHz base clock that boosts up to 4.8 GHz in non-AVX workloads. This CPU stands out as one of the few fully unlocked Xeon processors, allowing overclocking capabilities rarely seen in the workstation segment.

The frequency scaling becomes dramatic under specialized workloads. When running AVX2 instructions, the base frequency drops to 1.7 GHz with the slowest core operating at 2.9 GHz across all 86 cores. AVX-512 workloads push frequencies even lower, with the base clock falling to 1.3 GHz and all cores running at just 2.5 GHz. The most demanding scenario occurs with AMX (Advanced Matrix Extensions), where frequencies plummet to a base of 1.1 GHz and 2.0 GHz across all cores simultaneously.

These substantial frequency reductions highlight the thermal and power demands of vector and matrix processing operations. The published frequency tables provide workstation users with critical data for understanding real-world performance under sustained computational workloads, particularly for applications leveraging AVX-512 and AMX instruction sets for scientific computing and AI workloads.
