Neurophos, an Austin-based AI chip startup backed by Bill Gates’ Gates Frontier Fund, says it built an optical processing unit (OPU) named Tulkas T100 that delivers ten times the FP4/INT4 compute of Nvidia’s Vera Rubin NVL72 while using comparable power. The company attributes the improvement to a 1,000×1,000 photonic sensor, miniaturized optical transistors and a 56 GHz operating clock, enabling higher compute density per die.
Key Points
- 1Develops Tulkas T100 OPU with 1,000×1,000 photonic sensor and 56 GHz clock, claims 10× FP4/INT4 performance
- 2Uses much larger matrix and miniaturized optical transistors to increase compute density versus silicon photonics
- 3Suggests potential lower-power high-throughput AI inference accelerators for FP4/INT4 workloads in data centers
Scoring Rationale
Significant hardware claim with practical relevance, but single-source startup benchmarks reduce credibility and immediate impact.
