en.Wedoany.com Reported - US semiconductor connectivity solutions provider Astera Labs announced the Scorpio X series 320-channel intelligent optical switch on May 5, 2026, simultaneously expanding its Scorpio P series PCIe optical switch product line. Both product lines are already shipping to hyperscale cloud service provider customers, with volume production ramp-up set to begin in the second half of 2026.
The Scorpio X series is positioned as a high-radix, memory-semantic interconnect solution, designed specifically for production environments handling trillion-parameter models and distributed agent workloads. A single ASIC integrates 320 PCIe 6 lanes, delivering 5.12Tb/s of bidirectional bandwidth. CEO Jitendra Mohan stated in the official press release: "The Scorpio X series 320-channel high-radix AI optical switch can replace multiple traditional switches, enabling larger scale-out clusters within a single hop and reducing overall latency."
Memory-semantic architecture is the core feature distinguishing this product from traditional switches. The Scorpio X series allows GPUs and other AI accelerators to directly access resources across the entire optical network through native load/store operations, eliminating the need for CPU intervention for packet conversion. Accelerators can read and write remote data distributed across different nodes as if accessing local memory, transforming the entire optical network into a unified memory pool, eliminating the overhead of software protocol stacks, and maintaining low latency and high accelerator utilization in large-scale clusters.
The Scorpio X series is equipped with a hardware-accelerated Hypercast and in-network computing engine. Hypercast is Astera Labs' dedicated multicast mechanism for Mixture-of-Experts models and multi-GPU collective communication scenarios, supporting lightweight, pre-configurable multicast groups that distribute data to GPU nodes within the cluster with deterministic low latency, overcoming the bottlenecks of limited group capacity and slow configuration response found in traditional multicast solutions. The in-network computing engine offloads collective operations such as all-reduce and all-to-all from GPUs to the switch hardware. Astera Labs' internal analysis shows that overall collective communication performance can be improved by up to 2x, directly enhancing key metrics such as Time-to-First-Token and tokens per watt.
The product supports multiple interconnect protocols including PCIe, CXL, Ethernet, NVLink Fusion, and UALink, enabling unified deployment across accelerator platforms developed in-house by major cloud providers and AI labs, without the need to redesign the switching layer for specific hardware architectures. The companion COSMOS software suite covers unified management of optical switches, copper interconnects, and optical solutions, providing features such as device management, firmware updates, and real-time telemetry.
At the solution integration level, Scorpio X can work in concert with Aries PCIe 6 retimers, Leo memory controllers, and Smart Cable modules to form a complete interconnect system covering chip-to-chip direct connections, copper extension, and optical reach. Astera Labs will showcase the Scorpio X series and its PCIe 6 optical extension solutions at Computex 2026, held in Taipei from June 2 to 5.
Expanding the existing product line is a significant component of this launch. The Scorpio P series adds multiple configurations ranging from 32 to 320 lanes, forming a complete AI infrastructure switching chip portfolio with the X series, covering both front-end network interconnect and back-end scale-out fabric deployment scenarios, allowing data center architects to flexibly select models based on accelerator types and topology requirements.
Astera Labs concurrently announced its Q1 2026 financial results, reporting revenue of $308.4 million, a 14% sequential increase and 93% year-over-year growth, with PCIe 6 product portfolio revenue already accounting for over one-third of total revenue. CEO Mohan stated that the company will continue to expand investments around AI rack-level interconnect technologies.
As AI infrastructure enters the phase of large-scale production deployment, trillion-parameter models and agentic multi-step reasoning workflows are placing new demands on interconnect performance. The commercial delivery of Scorpio X provides hyperscale cloud service providers facing continuously expanding GPU clusters with a high-bandwidth, low-latency, protocol-compatible switching architecture. Astera Labs will participate in high-performance interconnect solution demonstrations during Computex 2026, where more details regarding PCIe optical link demonstrations are expected to be disclosed.
