You can’t buy the gpus individually, and even if you can on a secondary market, you can’t use them without the baseboard, and you can’t use the baseboard without a compatible chassis, and a compatible chassis is full of CPUs, system memory etc. on top of that, you need a fabric. Even if you cheap out and go RoCE over IB it’s still 400gbs hcas, optics and switches
Yea, a node in a cluster costs as much as an American house. Maybe not on its own, but to make it useful for large scale training, even under the new math of deepseek, it costs as much as a house.
They estimated $200k for a single NVIDIA GPU-based CPU complete with RAM and networking. That's where my number came from. (RAM and especially very-high-speed networking is very expensive at these scales.)
"Add it all up, and the average selling price of an Nvidia GPU accelerated system, no matter where it came from, was just under $180,000, the average server SXM-style, NVLink-capable GPU sold for just over $19,000 (assuming the GPUs represented around 85 percent of the cost of the machine)"
That implies they assumed an 8-GPU system. (8 × $19,000 = $152,000 ≈ 85% × $180,000)
