OpenAI Jalapeño chip beats Nvidia in inference benchmarks

OpenAI's first custom AI chip, Jalapeño, outperforms Nvidia's Blackwell and Rubin in throughput per watt and token latency on inference workloads. Developed with Broadcom, the general-purpose LLM accelerator delivers 1.5x to 1.9x more AI work per watt at peak throughput across three tested models.
