Astera Labs introduced Scorpio X-Series 320-lane switch targeting 49% collective IO reduction for fragmented AI workloads. Shipments to hyperscalers began, with broad ramp in H2 2026. Astera Labs this week introduced its Scorpio X-Series 320-lane smart fabric switch, targeting idle GPU compute in hyperscaler clusters. The memory-semantic architecture cuts collective IO by 49%, according to analyst Brendan Burke of Futurum [per the source]. Key facts Scorpio X-Series has 320 lanes for high-radix fabric switching. Memory-semantic architecture enables load/store accelerator access. Analyst: cutting collective IO by 49% boosts GPU utilization. Shipments to hyperscalers began; broad ramp in H2 2026. Hypercast engine offloads collective operations into the fabric. The gap between how AI clusters are designed and how they actually run is costing hyperscalers billions in idle compute. Astera Labs is attacking that mismatch with a new high-radix fabric switch that rethinks data movement at scale.…
