Rack-scale AI system on the new Cerebras Nexus platform, built from three WSE-3 Turbo processors in modular liquid-cooled compute backpacks. Cerebras says CS-4 delivers up to 30x faster inference than GPU systems, up to 10x more throughput per watt than CS-3, 750 PFLOPs of AI compute, 7.2 Tbps of I/O, 129.6 PB/s of memory bandwidth, and wafer-to-wafer latency as low as 2 microseconds for models above 50 trillion parameters.
Current production wafer-scale system, one WSE-3 per chassis, used for Cerebras Cloud, OpenAI Ultrafast, AWS disaggregated decode, and on-prem clusters. The 5nm WSE-3 is 46,225 mm2 with 4 trillion transistors, 900,000 AI cores, 44 GB of on-chip SRAM, and 21 PB/s of memory bandwidth, about 58 times the area of an Nvidia B200 die and thousands of times its on-chip memory bandwidth.
Current flagship wafer-scale processor inside CS-4. Same 4 trillion transistors, 900,000 cores, 46,225 mm2, and 44 GB of SRAM as WSE-3, clocked and packaged for roughly 2x the speed of the prior wafer, 250 PFLOPs of AI compute, and 43.2 PB/s of memory bandwidth per wafer. Redundant cores and fail-in-place routing are how Cerebras yields a dinner-plate-sized die.
