No.. If you bought vega 56s at launch (like I did). You would have 10X vega 56 = 4000USD @ 18kh/s. Vega 56s can easily hit 150W @ 2kh/s. His statement is fairly accurate. Hashing wise it's not that impressive. It's the power consumption where there's a big difference.
Lowest I ever saw the Vega 56 at was $450 - on a brief sale shortly before the stock on them disappeared due to Monero miners finding out about their performance.
Still the economics aren't all that much better - but the POWER USAGE is a ton better.
