That speedup compared to Nvidia's previous generation came nearly entirely from: 1) a small process technology improvement from TSMC, 2) more silicon area, 3) more power consumption, and 4) moving to FP4 from FP8 (halving the precision). They aren't delivering the 'free lunch' between generations that we had for decades in terms of "the same operations faster and using less power." They're delivering increasingly exotic chips for increasingly crazy amounts of money.
