Lightmatter, a startup valued at $4.4 billion, on Monday released two pieces of technology aimed at speeding up the connections between artificial intelligence chips.

Penn Engineers have developed the first programmable chip that can train nonlinear neural networks using light—a breakthrough ...

Fears that data centers would devour our power grid were rampant in the early 2000s. The solution wasn’t more power plants.

Silicon Valley startup Lightmatter revealed on Wednesday it had developed a new type of computer chip that could both speed ...

Kazu Gomi, president and CEO of NTT Research, has a big view of the technology world from his perch in Silicon Valley.

Instead of moving information between computer chips as electrical signals, Lightmatter's technology uses optical connections and ... image generators and other AI applications.

This causes a bottleneck for AI workloads that rely on huge clusters ... optical circuit switch that adapts the mesh of chip-to-chip connections within data centers on the fly.

a Silicon Valley-based AI chip company, and Canadian chip startup Ranovus said on Tuesday that they had been awarded a $45 million contract from the U.S. military to speed up connections between ...

Another area where innovation will reduce AI’s energy needs is the connections between chips. Even as transistors have gotten smaller and allowed a given space to pack more “punch,” chips ...

AI efficiency innovations are happening on three fronts: chips, connections, and AI architecture itself. AI-related chips have already improved their energy intensity by over 99% since 2008, and we ...
