Context Before
Since then, Groq’s roadmap has stalled due to execution, with no LPU 2 having been shipped. This leaves the Groq LPU looking even more dated against competing roadmaps. What was once a meaningful but still manageable node disadvantage versus 7nm-era peers has widened into a far sharper gap, with all leading accelerator platforms now moving onto 3nm-class processes in 2026.
Evidence
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.
Context After
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.
② Atomic Claim
後續的 Groq LPU 2 是為 Samsung Foundry 的 SF4X 節點設計，具體是在 Samsung Austin fab 生產，讓 Groq 得以延續「在美國國內製造」的訴求。
