I did a comparison of a Raspberry Pi to a Cray-1. It was... very impressive for how far it has come.
Cray-1 RPI Factor
Price $33M (2020 dollars) $75 (8GB) 440,000x
Weight 5.5 tons 45 grams 74,510x
Power 115 kW (@208 V 400Hz) 5.1 w 23,000x
Memory 8.39 MB 8 GB 0.001046 (1/953x)
Performance 160 MFLOPS 9.69 GFLOPS 0.01651 (1/60.56x)
I guess that's 32 nodes in the terms of your quote?
