The updated Wafer Scale Engine allows Cerebras to double the transistor and core counts on the monolithic chips, although the size and power requirements should remain close to the original gen 1 chips since the technology now uses TSMC's 7 nm nodes instead of the older 16 nm. It remains to be seen if Cerebras is going to double the amount of on-chip SRAM and the fabric bandwidth.
