Severe thermal throttling discovered in Apple's M2 MacBook Pro

Time will tell what this issue is but the person reporting it is leveraging controversy to get clicks here. I suspect manufacturing issue.<p>The SSD performance problem on the 256Gb models is a massive problem though.<p>Although after all this I&#x27;m still not sure why the M2 MBP exists. By the time it&#x27;s useful it costs nearly as much as the MBP 14&quot; for the same spec which is far superior. And if you want to cheap it out, the M1 MBA is probably a better deal because it&#x27;s far cheaper and perfectly adequate.

The prior model 14&quot; MBP could handle an M1 Max without thermal throttling, and that was a chip that reportedly consumes around 60W, and the M2 slots in underneath the M1 Pro. This is almost certainly a manufacturing defect specific to this, or some subset, of M2 MBP&#x27;s.<p>Looking at this guy&#x27;s youtube channel, he&#x27;s cranked out over six &quot;gotcha&quot; videos about the M2 alone. His channel is chock full of &quot;WHAT THEY DIDN&#x27;T TELL YOU!&quot; and &quot;DON&#x27;T BUY UNTIL YOU WATCH THIS&quot; clickbait nonsense.<p>Until someone who is reputable confirms this - like Linus Tech Tips - it&#x27;s a non-story.

For me it’s a non-story as I believe the main advantage of the M2 over the M1 is its 50% higher memory size (24 GB instead of 16 GB) and memory bandwidth. So if you stress all CPU and all GPU cores the same time the cooling can’t keep up. If the cooling can keep up when stressing only one of them it is enough in my opinion.

That really does not bode well for the upcoming fanless M2 Air.

The thermal throttling and high temps are interesting because I haven&#x27;t seen it reported before. The comparisons he makes to the m1 pro - I thought the m2 was supposed to site between the m1 and m1 pro in terms of performance, so not meeting m1 pro performance is probably by design, no?

After my 2018 top line Intel based MacBook Pro needed weird surgery involving me stacking thermal pads onto the motherboard to remain usable (not something I was thrilled to do with my expensive machine!), Apple is guilty until proven innocent to me on laptop thermal design.

HN: The M1&#x2F;M2s are the best thing that&#x27;s ever been invented in computing omg instructions per watt so good no need of a fan no cooling<p>Also HN: dismisses a real problem of their beloved CPU hitting temperatures that would make Intel laugh<p>Don&#x27;t worry, denial is the first step to acceptance.

TLDR is the M2 13&quot; Pro is about 10% faster than the M1 13&quot; Pro in his testing.<p>Wait, then what&#x27;s the problem? It has a poorly configured thermal management leading to oscillating power&#x2F;temperature. It&#x27;s pretty sloppy on Apple&#x27;s part, they&#x27;ll almost certainly fix it in a software update, and it&#x27;s not that likely most users will run into it before then. This guy needs to hype up every issue to drive traffic for his YouTube channel, fair, but not really something I&#x27;d personally get worked up about.<p>Edit: This kind of thing is why I don&#x27;t buy a new model or upgrade to a new major OS version until 3-6 months after release when the major issues are fixed or at least known.
