Startup claims light-based chip could deliver 10x Nvidia's performance at similar power

The concept centers on an optical processing unit – a chip that performs calculations using light rather than electrons. Neurophos says its technology could reach 470 petaFLOPS of FP4/INT4 compute, roughly ten times the performance of Nvidia's latest Rubin GPUs, while drawing similar power. For an industry straining against the...
