MediaTek’s latest announcement on the deepening of its long-term partnership with Nvidia repeatedly uses the term “rack-scale.” This is the key to understanding the announcement, and it directly validates the central conclusion of my research from more than two months ago: MediaTek has upgraded the strategic positioning of its AI business from "IC / ASIC design" to "system-level design." The announcement link: The announcement also explains how MediaTek plans to put this new positioning into practice. By working with Nvidia, MediaTek can bring custom chips and XPUs into Nvidia’s mature rack-scale ecosystem, so that once chip development is complete, they can be integrated more quickly into rack-scale systems for deployment in data centers and AI factories. For MediaTek, Nvidia’s mature rack-scale systems ecosystem means it does not need to start from scratch, giving this new strategy a much clearer path to execution. For Nvidia, MediaTek’s custom silicon design capabilities and customer base can help extend Nvidia’s rack-scale ecosystem further into the custom silicon market. This also explains why “rack-scale” is the key term in the announcement: it is where the two companies need each other most. MediaTek can move from chips to systems, while Nvidia can extend its rack-scale ecosystem into the custom silicon market, creating a win-win that opens up new growth opportunities for both.

MediaTek's Rick Tsai on their biggest bottleneck: "Supply chain does present challenges. Not just HBM but go down to substrate, etc. Being in Taiwan, it's almost like the center of AI infrastructure ecosystem really helps." There is not enough substrate at all... Via @BloombergTV
