GoKawiilCerebras to stack DRAM atop wafer-scale chips in upcoming CS-6 system
At Hot Chips 2026, Cerebras detailed its next two wafer-scale accelerator generations, including a new Nexus rack architecture for the CS-4 system that triples rack-scale performance using three WS-3T engines. The company also confirmed that its future CS-6 system will introduce 3D-stacked DRAM directly on top of its wafer-scale logic and SRAM, marking a first for its chip design.
