THE HAPPENING WORLD: A CPU Chip Bigger than Your Head: Cerebras Wafer Scale Engine 2
Cerebras Wafer Scale Engine 2 specifications:
- 850,000 cores
- 40 Gb on-chip SRAM
- 7 nm TSMC process
- 2.6 trillion transistors
- 46,225 mm² silicon area;
- 20 Pb/sec memory bandwidth
- 220 Pb/sec on-chip interconnect bandwidth
- 23 kW power dissipation (water cooled)
The wafer is designed with spare cores so that those with defects can be routed around, and hence fabrication yield is 100%.
