Going by the jump from 28nm to 14nm you'd expect around ~165-175W for Vega 64 power at 7nm. Looking at the updated adored navi cards, I think he's still a tad generous on the pricing, and I'd expect Navi to consume a smidge more than AMD's listed TDP(I believe he mentions that power consumption could be higher than his updated list, but I'll need to skim again).
I've been looking over some of the Gonzalo coverage and it seems at least plausible to me that it's PS5 with CPU at 1.6GHz(probably base for BC)/3.2GHz max. It's allegedly "Navi 10 lite". They were listing it with 1GHz core initially, then 1.8GHz later.
Polaris 10 RX 480 was a 150W TDP(listed) card that consumed more like 166W in heavy gaming. The year it released, Sony had it in the $399 PS4 Pro with a ~30% decrease in clock speed and lower memory bandwidth, total system power consumption at ~155W. A year later MS had it in the $499 Xbox One X at 6TF with total system power consumption of ~172W. They list a max core clock, but they are also power capping the GPU. I'd be curious to get a performance log and see how the core clock and wattage roll over a gameplay session.
Gonzalo with 44CUs/48CUs, 1.8GHz core, nice cooling and tuning gets you 10-11TF at $499. I guess I'm not a $399 believer anymore.¯\_(ツ)_/¯
Anyyyway...
