Context Before

Since Nvidia entered into a licensing agreement for Groq’s technology and hired Groq’s key people in December 2025, speculation has brewed on how exactly Nvidia will implement Groq’s technology. We believe that Nvidia will introduce a new LPU rack at GTC 2026. The LPU rack is designed to be used alongside Nvidia GPUs for inference.

Evidence

With CPX being designed specifically for inference pre-fill, the LPU system is designed for inference decode given the LPU’s emphasis on higher bandwidth SRAM.

Context After

This comes at the expense of total throughput so this LPU decode system could be positioned at serving requests that require very high tokens per second per user, with the user paying much higher $/token to compensate for higher cost to serve.

② Atomic Claim

CPX 是針對 inference pre-fill 設計；相對地，LPU system 因重視更高 bandwidth 的 SRAM，設計目標是 inference decode。
