OpenAI's New Jalapeño Chip Outperforms Nvidia in Efficiency Tests with Broadcom

Key Facts

In a move reflecting the growing trend among big tech firms to reduce reliance on traditional hardware vendors, OpenAI has revealed performance results for its new Jalapeño chip. According to reports, the custom-built inference chip outperformed Nvidia's GB300 in internal throughput and latency testing. The chip was developed in collaboration with Broadcom Inc and is specifically optimized for AI inference tasks rather than model training.

This development arrives amid intensifying competition in the semiconductor sector as OpenAI seeks to optimize operational costs and challenge Nvidia's market dominance. Per market data, AVGO (Broadcom) closed at $358.76, while NVDA (Nvidia) stood at $208.48 as of August 24, 2026. During the same period, peer stocks showed varied performance, with AMD closing at $456.75 and INTC at $87.26.

Investors are closely watching OpenAI's ability to scale production of these custom chips, especially with AVGO trading near its daily low of $358.71 at the August 24, 2026 close. Regarding upcoming catalysts, market participants are looking toward the FOMC Minutes on August 19 for broader monetary policy signals that could impact valuations across the high-growth semiconductor industry.
