Copper interconnect wall forces $4B Nvidia bet on silicon photonics for AI scale-out

Interconnect speeds must quadruple to 1.6Tbps by 2027 as Nvidia scales racks to 576 GPUs; copper hits physics limits (heat, signal degradation, crosstalk) past 800Gbps, making photonics the…

Photonic matrix multiplication demonstrated at near-zero energy, but GPU replacement remains distant

Lightmatter proved photonic processors can run AI workloads at GPU-level accuracy with drastically lower power; however, the speaker views full GPU replacement as a long-term fantasy, while…
