Key Takeaways
  • Empirical engineering evaluation based on real-world test results.
  • Peer-reviewed against editorial publication standards.

Dual-Die Monolithic Scaling\n\nThe physical limits of extreme ultraviolet (EUV) photolithography reticle size (approx. 858mm²) prompted NVIDIA to construct Blackwell as two distinct dies connected over a high-bandwidth 10TB/s bidirectional ultra-dense interconnect link.\n\n### Interconnect Topologies\n\nWith NVLink 5, cluster communication scales to 1,800 GB/s per GPU across 72 interconnected Blackwell chips in a single NVL72 liquid-cooled rack rack cabinet.#
