Your Next CPU is Bigger Than Your HEAD
Cerebras Wafer Scale 2 In a recent video titled "Your Next CPU is Bigger Than Your HEAD
Cerebras Wafer Scale 2," the focus is on a revolutionary AI processor that stands out for its massive size and capabilities. The Cerebras Wafer Scale Engine 2 (WSE-2) is a game-changer in the realm of AI computation, pushing the boundaries of what we consider to be a CPU.
Unraveling the Size and Scale
Historically, large CPUs have been associated with processors like Xeons or Threadrippers, typically maxing out at 800 square millimeters. In stark contrast, the WSE-2 measures an astonishing 46,225 square millimeters, making it the largest chip ever manufactured. This shift represents the increasing demand for specialized silicon designed for intense AI workloads, including both training and inference tasks.
A Deep Dive into AI Processors
The video explains the distinction between AI training—which is resource-intensive and memory-heavy—and AI inference, where algorithms are applied to real-world scenarios, such as image recognition. Cerebras's approach involves creating dedicated chips optimized for these tasks. Notably, their previous model, WSE-1, featured 400,000 cores and 18GB of SRAM; the WSE-2 doubles that capacity with 850,000 cores and increases the onboard memory to 40GB.
The WSE-2 System
Cerebras is not just selling the chip; it comes as part of a comprehensive system that takes up about a third of a full rack. This system includes liquid cooling and numerous high-bandwidth connection ports, showcasing the engineering required to maintain performance at such scales. The price tag for these systems is estimated to be in the millions, targeting industries requiring high-performance AI computations, such as pharmaceuticals and governmental research facilities.
Efficiency and Yield
One of the standout features of the WSE-2 is its impressive yield rate. Cerebras can effectively bypass defective cores, allowing them to maintain a hundred percent sellable yield. This innovative approach simplifies the scaling process for developers who often face complex coding challenges when distributing tasks across multiple devices.
In Summary
Cerebras’s innovative technology and their relentless push towards larger, more efficient AI chips mark a significant milestone in the industry. As they continue to refine their offering with the WSE-2, other chip manufacturers like AMD and Intel may need to reconsider their strategies to keep up with this unprecedented scale. The Cerebras Wafer Scale Engine 2 not only sets a new standard for performance but also catalyzes discussions about the future of AI computation.
