Cerebras Wafer-Scale Engine 3

Wafer-scale AI engine: trillions of transistors and hundreds of thousands of cores on a single TSMC 5nm die.

WSE-3 is Cerebras' third-generation wafer-scale processor. A single 5nm wafer holds 900,000 AI cores, 44 GB of on-chip SRAM, and a 21 PB/s fabric, delivering 125 PFLOPS of peak AI compute as the engine inside the CS-3 system.
