On the topic of power, I really don't understand how USB-C is supposed to replace charging cables. USB-C is limited to 100W. That's enough for a switch, phone or low power laptop, but if this[0] is anything to go by the 6 core intel laptop CPUs already eats 80W of power. Add an extra 2 cores and you might not even be able to sustain a CPU load without draining the battery. Not to mention much higher power draw GPUs.
My real question here is what's the plan? Because it's not possible to push 200-300W down a USB-C cable.

- MaddAgent 7y agoSo you're thinking the new MacBook Pro 16 with an 8 Core CPU and a GPU using the included 96Watt USB-C charger may drain the battery under full load?
- rhinoceraptor 7y agoIt will drain the battery at full load, the i9 is a 45 watt TDP and the RX 5500M is 85 watt TDP (plus display, ram, disk, etc). However, there's no way the cooling on the laptop can support that much power draw, so I'd expect it to throttle itself way before you'd drain the battery while plugged in.
- rhinoceraptor 7y agoBig gaming laptops will always require big power supplies, probably using barrel jacks. I've seen really gigantic ones that use two! But pretty much every other laptop can get away with well under 100 watts. I use a 30 watt USB C charger at home, and it's fine for using my 15" i7/560X MBP at my desk, because I'm not running it at 100% CPU/GPU for extended periods.
