Tesla also cut the memory for its AI6 chip by one third to 144GB of LP6 to avoid supply bottlenecks. These adjustments will have a negligible effect on the performance of the Optimus robots because memory bandwidth is a larger limiting factor than total storage, Musk said. The company held memory bandwidth constant during these reductions to maintain the processing efficiency of the hardware.
