Lattice Computing
Lattice Computing — The Next-Generation AI Compute Architecture
· GPU/SSD Tight Coupling · Microsecond Latency · 10x Bandwidth◆Definition in One Sentence
Powered by Lattice Fabric / Extended PCIe + , this pioneering architecture achieves tight GPU/SSD coupling: GPUs and NVMe SSDs are directly paired through the extended PCIe interconnect, with end-to-end data exchange completed entirely within the expanded PCIe domain.
▍Latency Comparison: Milliseconds → Microseconds
Traditional PCIe Networks — Millisecond-Level Latency
Lattice Interconnect — Microsecond-Level Latency
▍Lattice Interconnect PCIe Card
Note: The gold fingers plug into the server motherboard's PCIe slots; GPU interconnect ports bring external GPUs into the same PCIe domain via cables/backplanes, enabling tight GPU↔SSD coupling and microsecond-level data exchange.
▦Key Components & Specifications
