That's quite easy to prove.You work for the AIBS ? and know this for a fact ? Or because it's grey TIM you think it's all the same ? As has been proven by that video it is not normal TIM and a PCM TIM on the 4090FE. Even I didn't know that until he said what it was and knew PTM7000 as we have the stuff at work for our servers. Otherwise I would not had an idea what they used and thought it was normal stock grey TIM. Even Steve at GN didn't know and thought it was normal TIM.
See Techpowerup photos of 4090 Strix - PCM does not have viscosity like that, this is clearly normal tim:
Another good picture of Colorful, this is 100% not PCM:
Compare it to FE photos that's using PCM, it's more solid state and dry:
I went through all the teardowns and only FE is using PCM - on the fence with MSI - rest is definitely just a strandard TIM. By STRIX being the coolest card out of the bunch - you can assume PCM is not needed.
And no, I am not assumming grey = tim. There are other differentiative characteristics than color.
With such a large die as GPU there is little benefit of PCM vs good TIM. The gains in laptops are more pronounced, because the dies are much smaller
