Cerebras

This post benchmarks the Cerebras CS-3 against Nvidia's DGX B200 Blackwell GPU, demonstrating a 21x faster inference performance for LLMs like Llama 3 70B. It highlights Cerebras's advantage in memory bandwidth, keeping model weights on-chip to reduce latency. The post also details significant price-performance (32% lower cost) and energy efficiency advantages, along with improved accuracy in reasoning tasks. For training, Cerebras offers up to 10x faster time-to-train due to simplified scaling. Availability is broad for CS-3, while B200 is supply-constrained. Reliability and ease of use are rated as even, with Nvidia leading in ecosystem breadth.
