PACE2

Global – October 16, 2026 -- Lightelligence's PACE2 accelerator card combines a 128×128 optical matrix multiplier with more than 40,000 photonic devices, and the company rates both its optical and electronic cores at 32 TOPs peak performance.

Hybrid architecture pairs a photonic core with an electronic core

The card, released in 2025, uses a heterogeneous design. An optical tensor processing unit (PIC core) works alongside an electronic tensor acceleration unit and an optical computing control unit (EIC core). The chip runs at a 1GHz clock speed, and PIC latency is 200ps.

Lightelligence describes the 128×128 matrix as the largest optical computing matrix it has built. Matrix coefficients can be configured dynamically through APIs, so the card is programmable.
