Make it stick

🚀 Groq LPUs streamline AI inference, achieving exceptional speed and energy efficiency by focusing on linear algebra calculations.
⚙️ The programmable assembly line architecture allows seamless data flow between chips, eliminating bottlenecks that plague traditional GPU architectures.
🔄 Deterministic compute and networking guarantee predictable execution times for each operation, enhancing efficiency in processing.
📦 On-chip memory offers bandwidth ten times greater than that of GPUs, enabling faster data access without inter-chip communication delays.

Groq created the LPU, a new category of processor tailored for the unique requirements of AI.
LPUs execute large amounts of linear algebra operations critical in AI inference, providing a more efficient alternative to GPUs.

Moore's Law, which predicted continual doubling of processing power, has seen GPUs become complex but less efficient for AI tasks.
The shift towards AI workloads necessitated a rethinking of both hardware and software architectures leading to the development of LPUs.

Software-first Approach: Developers retain control over hardware utilization, simplifying the process of maximizing performance.
Programmable Assembly Line Architecture: Features data "conveyor belts" that facilitate data movement between functional units without needing synchronization.
Deterministic Compute and Networking: Execution steps are predictable, eliminating variability and ensuring efficiency across processing stages.
On-chip Memory: Memory is integrated into the chip, allowing for high-speed data access and reducing overall system complexity.

LPUs offer superior performance and efficiency, projected to continue improving faster than GPUs as manufacturing processes evolve from 14 to 4 nanometers.
Groq's inherent design principles ensure that LPUs will maintain a substantial performance advantage over traditional GPUs in AI applications.
