First of all, can we please stop this 16TF nonsense?
Vega64 is a 7nm chip. It is expensive as hell. It burns 300Watt. It isn't even close to 16TF. Thinking of designing a 16TF vega64 is simply impossible, end of story.
Anybody who thinks they will get a 16TF console should go see a doctor, seriously.

Vega 64 is not 7nm. It is 14nm. (Which is based on 20nm BEOL.)

Vega 64's 295w TDP doesn't mean that is what it actually consumes... TDP isn't a denominator that describes power consumption, but rather the "Thermal Design Power".
You will need to look at the actual power consumption charts for an accurate representation of power consumption.

I mean, Vega 56 is 210w and Fury X is 275w.
Yet in certain gaming benchmarks, Fury X is consuming as much power as Vega 56.

Yet in others it consumes significantly more power than Vega 64.

Don't get me wrong though, people focus on "flops" is getting rather tiresome, flops isn't an accurate gauge of a systems complete capabilities.

Secondly, the "Two XBox models" - I don't see that. Unless Microsoft is willing to lose a shitton of money on hardware.

People are basing this idea on the leaks.
Also Microsoft stated it was working on more than 1 console at last years E3.

Having two SoCs means double the development costs (and designing a 7nm chip is NOT cheap). It also means taking care of two supply chains, not just one. again, very expensive.

Or. One console is using a die-harvested SoC and not a separately designed one.

My guess is we'll see something like a 54CU 1200-1400MHz console, no more.

64CU tends to be the limit of Graphics Core Next right now, Navi isn't likely to deviate from that as it's not high-end hardware and Vega 2 certainly didn't.
And there are good reasons for sticking to that limit (or below). Whilst Graphics Core Next is proficient at compute it has a ton of bottlenecks that holds it back in gaming... Plus it doesn't implement newer, more modern technologies that has typically given nVidia the edge.

7nm should allow for an increase in clockrates though, Vega 7 is boosting to 1750mhz for instance, although consoles won't push that high for various reasons. (Cooling, power etc'.)
