Anyone know how thermal management is on high-end laptop-version Skylakes? I have a three-year-old Dell Precision 15" with a quad core i7 (Sandy Bridge) at work. If I throw work at all the cores simultaneously, it takes about 60 seconds before it starts throttling the CPU to avoid thermal overload... Which makes it a bit useless IMO. Has this improved recently?

I have the 6700HQ in an XPS-15, it never seems to throttle - for example earlier today when I built firefox with -j8 it just pegged all cores and never let up.

I can be a tad noisy in this situation as you would expect, but from what I have seen - and reviews back me up - it doesn't throttle.

Same here. Even the fan noise is quite acceptable in comparison with my old HP pavilion. The XPS sounds like a light breeze, whereas the HP sounded like a vacuum cleaner.

You mean that in addition to showing all cores fully used, the frequency didn't drop below base?

Yes exactly.

Thanks! Exactly what I was wondering.

According to this review http://www.notebookcheck.net/Dell-XPS-15-2016-9550-InfinityE... it has a serious heat problem.

Wow, that is one thorough review. But it looks like it confirms that throttling only occurs on battery power, never on AC power.

It does throttle on AC power. Look at the "temperature" paragraph

My i7-6700HQ (Lenovo Ideapad Y700) has been behaving much better under high load than the old Sandy Bridge i7-2630QM (Samsung RC512) I had been using. Though it being a "gaming" design with extra vents and heat exchangers may be helping there.
