NVIDIA Ramps Up Production for 'Groq 3 LPX': Low-Latency Vera Rubin Extension for High-Speed AI InferenceFollowing its late-2025 licensing agreement for Groq’s Language Processing Unit (LPU) architecture and key engineering talent, NVIDIA has officially transitioned the co-designed hardware into full commercial production. Branded as the NVIDIA Groq 3 LPX, the accelerator serves as an essential modular extension to NVIDIA's flagship Vera Rubin NVL72 platform.
While the full Vera Rubin NVL72 infrastructure handles both massive multi-modal AI training and reasoning workloads, the Groq 3 LPX system is strictly engineered for pure inference acceleration. Designed to serve cloud hyperscalers demanding extreme token throughput, benchmark testing on the Gemma 4 31B model demonstrated generation speeds reaching 3,400 tokens per second.
AI cloud provider Nebius has already been announced as the first anchor enterprise customer to deploy Groq 3 LPX units within its global cloud infrastructure.
Groq's LPU architecture enables ultra-low latency. Traditional GPUs rely on high-bandwidth memory (HBM), which has large capacity but suffers from memory bandwidth bottlenecks during tokenization. Groq 3 LPX utilizes static memory (SRAM) embedded directly on the silicon chip, eliminating memory bus latency and allowing models to generate output tokens nearly instantaneously without waiting for access to external memory.
Modern AI agents perform multi-stage reasoning, tool calls, and background loops that utilize millions of tokens. In the co-designed Vera Rubin architecture, Rubin's GPU handles the heavy "prefill" step (receiving massive amounts of alert messages and contextual information), while the Groq 3 LPX unit takes over the sequential "generate" step. This workload sharing prevents expensive GPUs from stalling during step-by-step tokenization.
Cloud providers like Nebius face increasing power and hardware constraints. Dividing inference workloads onto LPX racks enables cloud data centers to achieve higher token yield per megawatt. Delivering 3,400 tokens per second enables real-time voice translation, automated code execution, and immediate interactive agents. This allows cloud service providers to monetize high-speed APIs with significantly lower operating costs.
