WSE-3 packs 4 trillion transistors, 900,000 cores and 44 GB of on-chip SRAM with 21 PB/s of internal bandwidth, sidestepping the HBM bottleneck entirely. The trade: models must be sharded across machines for weights, which Cerebras turned into an inference-speed story — serving Llama-class models at thousands of tokens per second. G42 of the UAE is its anchor customer; the company filed to IPO in 2024.","attrs":[{"g":"Overview","l":"Designer","v":"Cerebras Systems"},{"g":"Overview","l":"Announced","v":"March 2024"},{"b":"Vendor spec","g":"Manufacturing","l":"Foundry / process","v":"TSMC N5, single full wafer"},{"b":"Vendor spec","g":"Manufacturing","l":"Transistors","v":"4 trillion"},{"b":"Vendor spec","g":"Manufacturing","l":"Die size","u":"mm²","v":"46,225"},{"b":"Vendor spec","g":"Memory","l":"On-chip memory","v":"44 GB SRAM at 21 PB/s"},{"b":"Vendor claim","g":"Compute","l":"FP16","v":"125 PFLOPS (with Cerebras sparsity)"},{"b":"Vendor spec","g":"Power","l":"System power","v":"~23 kW per CS-3 system"},{"b":"Vendor spec","g":"Physical","l":"Cores","v":"~900,000"}],"kf":{"node":"TSMC N5","year":2024,"class":"Wafer-Scale","tdp_w":23000,"mem_bw":21000,"memory":"44 GB on-chip SRAM","designer":"Cerebras"},"aliases":["WSE-3","Cerebras","wafer scale engine"],"ticker":null,"exchange":null,"hq":null,"founded":null,"website":null,"status":"Shipping","region":null,"asof":"2026-01-15","sources":[{"url":"https://www.cerebras.ai/press-release/cerebras-announces-third-generation-wafer-scale-engine","label":"Cerebras WSE-3 announcement"}]},"meta":{"found":true,"count":1,"served_from":"site cache (no live upstream calls)","as_of":"2026-10-14T06:07:48+00:00","disclaimer":"Research and information only — not investment advice.
