Faster inference from Cerebras, Beats Blackwell
Nov 6, 2025

Summary
This post benchmarks Cerebras hardware against NVIDIA Blackwell GPUs for AI inference, specifically for the GPT-OSS-120B model. It demonstrates Cerebras's continued leadership in inference speed, achieving over 3,000 tokens/sec compared to Blackwell's 650 tokens/sec, a 5x advantage. The post attributes this to Cerebras's wafer-scale architecture storing the entire model on-chip, eliminating GPU bandwidth limitations. It also analyzes price-performance, showing Cerebras offers a better ratio despite a higher per-token cost.
