Context Before
Source: Groq, SemiAnalysis
The data flow and instruction flow design requires fine-grained pipelining to achieve high performance. Since LPU architecture makes computation deterministic, the compiler can aggressively schedule and overlap instructions to hide latency. The LPU’s use of high bandwidth SRAM and aggressive pipelining are the two main factors that enable LPU’s low latency.
Evidence
The 14nm node was mature, relatively well understood, and suitable for an initial chip where architectural differentiation mattered more than pushing its silicon to the leading edge
Context After
One of the selling points is that the chip can be manufactured and packaged entirely in the United States compared to their competitors being heavily reliant on the Asia semiconductor supply chain: logic and packaging in Taiwan, with HBM from Korea.
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.
② Atomic Claim
14nm 製程成熟且理解充分，適合首代晶片，因為當時架構差異化比追求最先進製程更重要。
