This reply repeats the same reported AMD hardware update: Samsung is close to signing an HBM4 contract for Helios, AMD’s rack-scale AI server.
- Helios bundles 72 Instinct MI455X GPUs and 18 Epyc Venice CPUs into one steel rack.
- The system includes networking and software inside the box, pushing a rack-as-a-product model.
- The memory comparison remains the main headline: 432GB per MI455X GPU versus 288GB on Nvidia’s Rubin.
