Intel Publishes "Granite Rapids-WS" Xeon 600 Turbo Frequencies, AVX-512 and AMX Slash Boost Speeds

Key Takeaways

• Xeon 698X offers 86 cores, 172 threads.
• Base 2.0 GHz, up to 4.8 GHz non‑AVX boost.
• AVX‑512 boost limited to 2.5 GHz across cores.
• AMX workloads drop to 2.0 GHz sustained.
• First Xeon WS with full overclocking support.

Summary

Intel has released the Granite Rapids‑WS Xeon 600 Series for workstations, publishing detailed turbo frequency tables that show core boost behavior across instruction sets. The flagship Xeon 698X packs 86 cores and 172 threads, with a 2.0 GHz base and up to 4.8 GHz boost in non‑AVX workloads, but frequencies drop sharply to 1.7 GHz (AVX2), 1.3 GHz (AVX‑512) and 1.1 GHz (AMX). The chip remains fully unlocked, allowing overclocking—a rarity in Xeon workstation CPUs. These tables give system builders precise performance expectations for heavy vector and matrix workloads.

Pulse Analysis

Granite Rapids‑WS marks Intel’s most aggressive entry into the high‑end desktop (HEDT) segment in years, directly challenging AMD’s Threadripper Pro line. By publishing granular turbo frequency tables, Intel provides transparency that was previously limited to benchmark leaks, allowing OEMs and integrators to model thermal and power envelopes with confidence. The Xeon 600 series leverages the 4‑nm Intel 7 process and introduces a massive 86‑core SKU, positioning the platform for workloads that demand massive parallelism, such as 3‑D rendering, simulation, and large‑scale data analytics.

The tables reveal a steep frequency penalty as workloads move from scalar to vector instructions. Non‑AVX code can see the flagship chip reach 4.8 GHz, but AVX‑512 workloads are capped at 2.5 GHz across all cores, and AMX matrix operations fall to a sustained 2.0 GHz. This behavior reflects the power‑intensive nature of wide‑width SIMD and matrix extensions, forcing system designers to balance core count against clock speed for AI inference and scientific computing tasks.

Intel’s decision to keep the Xeon 698X fully unlocked is a notable departure from traditional workstation CPUs, hinting at a broader strategy to attract enthusiasts and niche enterprises that value custom tuning. The detailed boost data also aids software vendors in optimizing compilers for the new instruction sets, potentially unlocking further performance gains. As organizations increasingly adopt AI‑accelerated pipelines, the Granite Rapids‑WS platform offers a compelling blend of core density and configurable performance, setting the stage for the next generation of compute‑intensive solutions.
