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 ?

How did you disassemble it? Can you share some insights with me about that?

AFAIR you unscrew all screws on the backside of the card, that should lose the complete heatsink/shroud construction. From there, you'll find more screws that connects the shroud to the heatsink.

My 6800XT is mostly at 75 hot spot without changing anything on it.

Even in GPU intensive games like Cyberpunk 2077 or even War Thunder?

I forgot to mention: I play with a 3400x1440 resolution. Thats' twice the pixels of 1920x1080.

SWFT

My question is do you or anyone know what kind of performance/stability improvements I can get by getting my hotspot temps under control?

Besides Games:

1. use fancontrol to control your... fans: https://getfancontrol.com/ and create a fan curve that is useable
2. if possible, deshroud your GPU. The plastic covers a lot of hot air.
3. when you have a backplate on your GPU, check if its thermically connected to the board via thermalpads. if not, get some thermalpads (not the cheap one I had but pads with a high heat transfer of at least 10 W/(m*k). Also be sure, that your backplate is metal not plastic
4. cover at least the areas of the VRM and VMEM like in this picture (not mine, I just found it)
5. repaste your GPU. Or use these: Thermal Grizzly Kryosheet. But they are a) expensive and b) electronically conductive, so make sure it sits on your gpu and does not touch anything else. But they have a great impact on heat transfer
6. Or, if you have the money, get a Raijintek Morpheus 8069. Add some nice fans to it and it should help you

Ingames:

1. don't use TAA with high settings, that will heat up your mem
2. use the chill feature that is included in the drivers. You limit the frames, therefore your GPU doesn't have to work as hard to get high FPS.
3. Shadows/RTX in games also use a lot of power... seriously.
