What is an LPU?
LPU
A Language Processing Unit (LPU) is a specialized hardware accelerator designed specifically for sequential language processing tasks, such as LLM inference. LPUs focus on minimizing memory bandwidth bottlenecks to enable extremely high token generation speeds.
Detailed Deep Dive
Language Processing Units (LPUs) are custom hardware accelerators designed specifically to minimize memory access bottlenecks during sequential token generation. Unlike general-purpose GPUs that excel at massive parallel math, LPUs use synchronous compiler scheduling and SRAM storage to feed model weights to processing cores instantly, allowing interactive chat APIs to run at hundreds of tokens per second.
Frequently Asked Questions
Q:Who created the LPU?
Groq developed the LPU architecture using a software-defined Tensor Streaming Processor.
Q:Why is an LPU faster than a GPU for inference?
LPUs use static compiler scheduling to fetch weights instantly, bypassing the memory access latency common in GPUs.

Inference chip startup Groq raises $650M to grow its cloud platform
Seven months after inking a $20 billion chip licensing deal with Nvidia Corp., Groq Inc. today announced that it has raised $650 million in funding. Growth investment firm Disruptive and hedge fund Infinitum led the round. Groq has developed a chip design called the LPU that's specifically optimized
