OpenAI’s Jalapeno chip outperformed the GB300 on power and speed, according to OpenAI

OpenAI’s Jalapeno inference chip, co-designed with Broadcom, delivered higher AI work-per-watt and faster response times than Nvidia’s GB300 while consuming 700 W, though it was not benchmarked against Nvidia’s newer Vera Rubin. It runs a small OpenAI model and third-party models from DeepSeek, Moonshot and Kimi, showing the greatest advantage on Kimi. A second version is expected within months, and a third-generation design is already planned.
