Hotter-than-ever Intel Arrow Lake and Panther Lake thermals could be on cards as increased TJMax limits leak

[Redaktion]

Intel Arrow Lake is the next desktop architecture from Team Blue that is set to rival AMD Zen 5. Among other architectural enhancements like new P and E cores, the Core Ultra 200 CPUs might also bring different thermal characteristics than their predecessors as a new leak suggests that Arrow Lake and Panther Lake have increased TJMax limits.

Insert "this is fine" dog in burning room meme here.

NOT INTEL VERY BAD.
Once again the same story is repeated as with the 13gen and 14gen that many of them are burning and we repeat the same mistake again, I don't understand it, Intel and everything increasing speeds which what it does is drain the batteries of the laptops and wear out the the processors, definitely not intel.

Quite impressive clickbait article, especially the title itself. The author will, one day, realize that Tjunction and Tjmax aren't the sustained operating temperature and that a CPU with high Tjmax can have lower averages and peaks than a CPU with low Tjmax. Thus the "Hotter-than-ever" part is a literal clickbait in its pure definition.

My 13700K has Tjmax 100°C, I'm yet to see it anywhere near it including now at summer with ambient temp 32°C inside. Only rendering in After Effects is actually pushing it to high 80s-low 90s, but still solid 6-8°C below its max.

Tjunction is just the maximum (Tjmax) allowed temperature at the CPU die, higher the Tjmax generally means safer and better CPU because the manufacturer has more trust in their product.

I would rather have a CPU with Tjmax 200°C than a CPU with Tjmax of 50°C; the former surely wouldn't throttle or die for no reason as soon as it gets a bit hotter in the room.

It means that they now have more wiggle room, which means that they don't think it'll break at higher temperatures.

But it also means that Intel now has the potential of going even hotter than before (even more power) without breaking.

Seeing that Intel's only way of catching up with AMD is by pushing more and more power, being able to have higher CPU temperatures than before sets a dangerous path to even higher power outputs than today, making efficiency plummet even more against AMD.

I'm not sure who'd want Intel CPUs nowadays, nor in the near future unless they up their game in efficiency quickly.

In fact, the problem is not in the heating of the SoC (although a scandal is currently flaring up with processors 13-14 and even 12 series HX from Intel, even in laptops with their instability even without overclocking), but in the fact that high temperatures on the SoC automatically mean increased requirements for the power supply of the SoC, and therefore for the cooling system, especially if the goal is a balanced indicator of performance and silence.

Obviously, the power circuit of the motherboard, which can withstand higher temperatures and currents, is more expensive, i.e. Intel, in fact, deliberately, with its cheating, provokes an increase in the cost of motherboards, including the cooling system.

I was hoping that with the release of Lunar Lake made on TSMC's advanced process technology, Intel would be able to regain its technological leadership at the 1W performance level, but if this is not the case, it is a fiasco for Intel and a path to oblivion...
