You mean this part? "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)
