Cerebras CEO Explains Why Wafer-Scale SRAM Beats GPU HBM by 2500x in LLM Inference
rohanpaul_ai · x · 2026-10-03
On The MAD Podcast, Cerebras CEO Andrew Feldman explained why the company's wafer-scale architecture is 2,500x faster than GPUs during LLM inference: in the sequential decode phase, model weights must move from memory to compute before every token. GPUs fetch weights from HBM, while Cerebras keeps them in far faster SRAM spread across its wafer-scale processor.
