This is really not true. With a decent motherboard and sufficient cooling, you can force the big cores to stay virtually locked at peak clock speeds. Der8auer does it for a Ryzen 8000 APU here just as an example: https://youtu.be/VNYx72Elgss?t=335 https://youtu.be/VNYx72Elgss?t=335
- wtallis 3y agoPutting a laptop chip into a desktop platform and giving it water cooling and unlimited power delivery isn't a particularly strong counterexample. That's nowhere near the operating point the silicon was designed for, and the fact that AMD shipped a few SKUs that enable such usage as an afterthought doesn't disprove much.
