The AMD version is here. Seems to be an analogue of Honeywell PTM7950 which is used in laptops. Apparently it's good for longterm application to direct dies and is stable. The thermal conductivity is similar to Arctic MX4/MX5:

Linus tech tip recommends cooling it down before applying. Room temp is enough to make it too hard to apply.

Same for most PCM and putties. Putting them in the fridge for 3 hours is pretty standard advice.

If you have mX-4 id just use that.

This is to be used instead of thermal paste? Single use I presume?

Yes - it is single use for longterm applications. People have used it in graphics cards,Steam decks,laptops,etc. (edited)

What’s the cheapest thermal pad for a ryzen 3600? I’ve got a sachet of MX-4, so maybe I should just use that!?
1st Mar
Yeah that's fine. Just use what you have. Its only a 65w cpu

Tldr not really needed in consumer applications. Realically people will upgrade their units way before paste dries up.
I've got my machine (i7) for ~8 years and still sitting 20-25c idle.

PS, thermal pads is very sensitive to pressure applied so will need to mount the correct torque/pressure. (edited)

Rubbish, paste in gaming laptops dries very quickly which reduces efficiency. Laptops that come with liquid metal often need repasting inside of a year as the heatsink absorbs the LM or it leaks out the side causing temperatures to spike.
This stuff is especially suited to modern laptops that are difficult to take apart meaning you only have to do it once and forget it, they are also perfect because laptop heatsinks never sit level they often have high and low spots and this stuff fills the voids perfectly.

One machine isnt indicative of a pattern.

The way they misspelt "helios" and just rolled with it is classic Chingrish.

What about...

"can be directly affixed to the CPU/heatsink base without the need to apply"

Why is the AMD version more expensive when it's smaller?

Lots of people are saying it is the same thing. The spec sheet is identical:
