- karmakaze 3y agoThis April 2021 Anandtech article says it was due out in Q3 2021, with the first Gen1 out in August 2019, 2 years earlier. > Two years ago Cerebras unveiled a revolution in silicon design: a processor as big as your head, using as much area on a 12-inch wafer as a rectangular design would allow, built on 16nm, focused on both AI as well as HPC workloads. The design for 100% yield is interesting. > initially Cerebras had 1.5% extra cores to allow for defects, but we’ve since been told this was way too much as TSMC's process is so mature [0] https://www.anandtech.com/show/16626/cerebras-unveils-wafer-scale-engine-two-wse2-26-trillion-transistors-100-yield https://www.anandtech.com/show/16626/cerebras-unveils-wafer-...
