Indeed.
I have a Thinkpad that has an i7-7700HQ, that's a 35W TDP beast and even under very heavy load I still get 90 minutes out of a 72 watt-hour battery and it gets pretty warm (and the TP has excellent cooling), 200W would melt your legs.

So combining the wider area that dissipates heat with the fact that hot spots are actively cooled means a laptop can easily go over the above mentioned 60W for prolonged periods. And power consumption tends to add up from sources that are otherwise not very power hungry themselves (compared to a CPU or GPU). A few W with the LCD, a few with the SSD/HDD, etc.
- xxs 8y agoIntel TDP is a sham - it's based on the published non-turbo frequency which is 2.8GHz. My primary laptop has its CPU undervolted (offset) by whopping 170mv, effectively around 30% lower power consumption.
