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?
- tavert 11y agoMy 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.
- JetSetWilly 11y agoI 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.
- Ruud-v-A 11y agoSame 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.
- MichaelGG 11y agoYou mean that in addition to showing all cores fully used, the frequency didn't drop below base?
- JetSetWilly 11y agoYes exactly.
- semi-extrinsic 11y agoThanks! Exactly what I was wondering.
- alexbel 11y agoAccording to this review http://www.notebookcheck.net/Dell-XPS-15-2016-9550-InfinityEdge-Notebook-Review.156354.0.html http://www.notebookcheck.net/Dell-XPS-15-2016-9550-InfinityE... it has a serious heat problem.
- semi-extrinsic 11y agoWow, that is one thorough review. But it looks like it confirms that throttling only occurs on battery power, never on AC power.
- alexbel 11y agoIt does throttle on AC power. Look at the "temperature" paragraph
