Context Before
Groq
First up is the Groq LPU. One of the most significant recent events in AI infrastructure was Nvidia’s “acquisition” of Groq. Strictly speaking, Nvidia paid Groq $20B to license their IP and hire most the team. This functions almost as an acquisition, though its structure technically falls short of it being legally considered as one, thereby simplifying or obviating the need for regulatory approvals. Given Nvidia’s market share, if this transaction were structured as a full acquisition and were put to anti-trust review, such a transaction would likely not go through. The other benefit is that it avoids a drawn-out transaction closing process. Nvidia got instant access to Groq’s IP and people. This is why, less than four months after the deal was announced, Nvidia already has a system concept that is being integrated into the Vera Rubin inference stack.
Evidence
Let’s now go through a refresher on the LPU architecture to see how Groq’s LPU complements Nvidia’s GPU. For more details see our original Groq piece. ↗ The premise from that piece remains unchanged: the standalone Groq LPU system is not economical for serving tokens at scale, but it can serve tokens very quickly which can demand a large market premium. This is the premise behind how LPU fits into a disaggregated decode system.
Context After
LPU chip
Groq’s first and only publicly announced LPU architecture was detailed in their ISCA 2020 paper. Unlike typical hardware architectures connecting many general-purpose cores, Groq re-organized the architecture into groups of single-purpose units connecting to other groups of different purposes, and they named the groups “slices.” Between functional units are streaming registers, scratchpad SRAM for functional units to pass data to each other. Groq opted for single-level scratchpad SRAM instead of multi-level memory hierarchy to make the hardware execution deterministic.
② Atomic Claim
先前文章的核心看法仍未改變：獨立運作的 Groq LPU 系統，在大規模 token serving 下並不具經濟性。
