Startup's Light-Speed Chip Tech Could Enable Massive AI Supercomputers
-
Most AI experts agree that advancing the field depends on building massive supercomputers with chips that can communicate at faster speeds.
-
A startup called Lightmatter has a technology called Passage that allows chips to talk directly using light, which could enable supercomputers on an unprecedented scale.
-
Passage eliminates the conversion bottleneck between optical and electrical signals, allowing data to move between chips at 100x the usual bandwidth.
-
Lightmatter claims Passage will allow over 1 million GPUs to run in parallel for AI training by 2026.
-
Companies like Nvidia are also working on new interconnect technologies to link AI chips together at higher speeds to power next-generation algorithms.
