Nvidia’s $3.5B MediaTek Bet Reveals Its Plan for Tackling Big Tech’s AI Chip Buildout

Nvidia is investing $3.5 billion in MediaTek through convertible bonds, announced 31 August 2026, deepening a partnership spanning AI data centres, RTX and DGX Spark-class PCs and automotive platforms. MediaTek will adopt Nvidia’s NVLink Fusion and NVHBM interconnects to design custom chips for AI companies and hyperscalers that plug straight into Nvidia-based data centres. This analysis covers what the deal includes, why it lands as Amazon, Google, Microsoft, OpenAI and Anthropic build their own silicon, MediaTek’s $2 billion-to-$12 billion data-centre ambition, the risks, and what it means for businesses buying AI services.

OpenAI Says Its Jalapeño Chip Can Power Faster AI Responses Than the Competition

At the Hot Chips conference on 25 August 2026, OpenAI published the first benchmark results for Jalapeño, the custom inference chip it built with Broadcom. On SemiAnalysis’s InferenceX benchmark, OpenAI reported 1.5x to 1.9x more work per watt and 1.7x to 3.6x lower end-to-end latency than an Nvidia Blackwell system, rising to 4.1x faster on highly interactive workloads. Here are the numbers, the architecture behind them, what OpenAI still has not disclosed, and what it means for anyone buying AI capacity.
