The company says each wafer runs up to twice as fast as the prior generation, and the new power, cooling, and I/O architecture draws more performance out of each wafer.\u003c/p\u003e\u003cp\u003eThe system claims inference speeds up to 30 times faster than simple GPU setups, and can process over 1,000 tokens per second on models exceeding 10 trillion parameters. Cerebras states the CS-4 improves throughput per watt by up to 10 times compared to its predecessor, the CS-3.\u003c/p\u003e\u003cp\u003eBy placing the power supply 0.5mm from the processor, roughly 100 times closer than on traditional GPU boards, the design reduces power loss and doubles the power that can be supplied.
