Citing an Epoch AI breakdown, the post discusses the upfront costs of a 1GW AI data center, which are around $37.2 billion. The most expensive components are servers and GPUs, rather than land and power.
Key points include:
- Servers account for about $21 billion, with GPUs taking the lion's share
- Facilities/buildings cost around $11 billion
- Network infrastructure is roughly $4.9 billion
- Land and power access combined are only about $330 million, less than 1%
The author argues that at $21,000 per kilowatt, such an AI data center is "actually quite cheap," and believes there is room for NVIDIA-related costs to double or triple in the future.
