Operational Details
  • Hardware Architecture: Built with advanced 5-nm chips in collaboration with TSMC, providing up to a 40% efficiency improvement over older S19 models.
  • Acoustic & Thermal:
    • The Air-Cooled version uses four high-speed fans, generating approximately 75–76 dB of noise.
    • The Hydro and Immersion versions are significantly quieter, making them better suited for noise-sensitive industrial environments, though they require specialized cooling infrastructure.
  • Power Requirements:
    • Air-cooled units typically require 220–277V.
    • Hydro and Immersion units often require 380–415V three-phase power, suitable for industrial-scale data centers.
