Context Before

The follow on Groq LPU 2 was designed for Samsung Foundry’s SF4X node, specifically at Samsung’s Austin fab, allowing them to extend the pitch that Groq is fabricated domestically in the USA. Samsung would also provide support for the back-end design. The choice of Samsung was driven by favorable terms / investment, with Samsung Foundry struggling to find customers for its advanced nodes and missing out on an AI logic customer.

Evidence

Unsurprisingly, Samsung was a key investor in Groq’s subsequent Series D in August 2024, and most recently in September 2025 before the Nvidia “acquisition.”

Context After

However, the Groq LPU 2 was never productized because of design issues. The C2C SerDes on the chip couldn’t hit the advertised 112G speed which caused the design to malfunction, as we detailed long ago in the Accelerator model. ↗ The third generation Groq LPU is the one that Nvidia will be productizing.

② Atomic Claim

Samsung 隨後成為 Groq 2024 年 8 月 Series D 的重要投資人，並在 2025 年 9 月、Nvidia「收購」前再次投資。
