The DX12U API is more unified with PC, but that doesn't mean it is less low-level. Actually the inverse is true:

Fiat punto is actually faster than bicycle.
Saying that DX12 is "more low level" means nothing, if they compared it to another DirectX version.
Compared to PS5 APIs I mean. unless there is hard data it could be that
Old DX = 100% base level
New DX = 80% base level
PS5 API = 60% base level
Lower number is "closer to the hardware", numbers pulled out of thin air. Point is, that if they compare DX to DX, yes they can claim it is lower level now, but it tells nothing about DX vs PS5.
It is more likely that APIs that are made for limited amount of hardware (ps5 only or ps4+ps5) are more specialized than APIs that have to work on tens of thousands PC hardware combinations + 5-6 xbox versions.
But xbox were able to cool a more powerful gpu in a smaller form factor with near silent accoustics? If ps5 was more powerful and smaller I could understand your argument that this was the only way to keep it quiet but clearly this is not the case.
Do you have proof of this? I highly doubt the series x will not adjust clocks at any time. What about just sitting on the home screen or watching Netflix? Is this gonna be 12 TF? Digital foundry have already measured different power draw for different games, indicating different clocks for cpu and gpu.
Look guys I have a ps5 on coming on pre order. Im not getting a series x because I have a pc. I just think we should be wary of what sony is saying about variable clocks as to me it doesn't seem great.
Series X and PS5 have almost the same internal volume
7936 cubic centimeters for Xbox Series X
10 000 cubic cm for ps5 (but it is not straight box so it is actually less than that and if we count only the black part of the console, it is way less)
Until there is professional noise measurements made on sound laboratory either of those are not "near silent" as people talk out of their ass and even noisy systems are nearly silent to some people.
And less power draw at netflix doesnt mean it downclocks.
You can force your PC to run at full clocks at desktop, but power draw isnt same as using those full clocks in benchmark software
power drawn depends of the load too.
