It definitely is. Apple's mistake with the Intel Macs was refusing to throttle the chips before they hit their T junction temp (~95c). This is why a lot of Wintel machines will max out around 70-80c in sustained load while Macs will fly past those temps.
The same behavior is present in both Intel Macs and Apple Silicon chips - you can very nearly boil water on your Macbook if you push the GPU with sustained load like LLM prefill.
