AM4 has been introduced in March 2017, the last CPU was released March 2022 (5800x3d) and there are rumors that more AM4 are (rumour) still in development

So it’s likely that AM5 will at least last 5 years, if not longer

could you compare the PTM7950 thermal pad with the Thermal Grizzly Kryosheet Thermal pad if possible?

I do use the Kryrosheet on my CPU… it’s awesome

But can it run … a City Skylines 2 city with half a million residents without slowing down to 8-12 seconds per 1 ingame minute ?
