Yes the whitepaper talks a lot about this cooling. https://f.hubspotusercontent30.net/hubfs/8968533/Cerebras-CS-2-Whitepaper.pdf https://f.hubspotusercontent30

The traditional computer included in the box is probably quite high end and power hungry too so that it can provide enough data to maintain those bandwidths. They don't appear to sell the chips by themselves. I think the comparison is with an equivalent gpu cluster like the nvidia DGX systems or HPC CPU nodes. The DGX A100 is 6.5kW for example, https://images.nvidia.com/aem-dam/Solutions/Data-Center/nvidia-dgx-a100-datasheet.pdf https://images.nvidia.com/aem-dam/Solutions/Data-Center/nvid... The Cerebras system fits 15 rack units which is more than 2x larger than the DGX (6.5U). A similar 15 node HPC server with CPU is probably not that far from 15kW either (2 socket per node, 250W per CPU is already 7.5kW, then add RAM etc.) so by HPC standards it's less "full room of servers" than "single cabinet".
