Cerebras Wafer Scale Chip With 1.2 Trillion Transistors

The Cerebras Wafer Scale Engine (WSE) was presented at Hot Chips. Sanders Olson provided Nextbigfuture with the presentation deck.

The Cerebras in the most powerful processor for AI with 1.2 trillion transistors.

It has
* 400,000 AI-optimized cores
* the wafer has 46,225 square millimeters of area
* it is silicon
* 1.2 trillion transistors
* 18 Gigabytes of On-chip Memory
* 9 PByte/s memory bandwidth
* 100 Pbit/s fabric bandwidth
* TSMC 16nm process.

It has room to drop to the 7 nanometer or eventual one nanometer lithography. A next generation wafer chip at 7 nanometers is already in development and will have 2.6 trillion transistors. Getting to 1 nanometer would mean about 25 trillion transistors if the same scaling occurred.

The CS-2, when it becomes available, will feature:

* 850,000 AI optimized cores
* 2.6 trillion transistors
* TSMC 7nm process
* It is working in Cerebras labs today.

Cerebras CS-1: Cluster-Scale machine is Deep Learning Performance in a Single System. It is powered by the Wafer Scale Engine. It has programming accessibility of a single node, using TensorFlow, PyTorch, and other frameworks. Deploys into standard datacenter infrastructure. Multiple units delivered, installed, and in-use today across multiple verticals.

It is built from the ground up for AI acceleration.
