Cooling is going to be crucial for laptops, and I'd expect it to be even more so in the future.

I've said it before but I am thoroughly disappointed with Dell's cooling setup on the G series & XPS laptops. For the TDP & performance offered the cooling setups are undersized by at least 30% of what you'd expect them to be. So if you see a Dell being benchmarked I can almost guarantee it's doing so while hitting the 98C throttle.

Not for these 15w parts. 13-15 laptops have more than enough cooling. Also, this review is very limited. I want to see some actual gaming.

I wish that was true, they unfortunately do not have proper cooling.

They should have enough cooling for the short bursts that laptops need. Once you start asking more out of it my best guess is that these Ice Lake CPUs would obliterate any laptop cooling in existence.

Notebookcheck tested a XPS with one of these and started to throttle real hard after the fourth Cinebench run. Other laptops with this CPU started throttling after the first run.



There was a video of that same XPS throttling after a few seconds and increasingly doing so for nearly three minutes:

Intel's 10nm beat AMD's 12nm+ by 10% and you call that impressive?

That's a pretty hefty price for a 10% advantage. Lose your IPC advantage in desktop and enterprise for a 10% lead in mobile-GJ Intel! That 10nm node is a gonna bring them loads of cash!

41% more battery life along with faster IPC in a smaller form factor.

Yes, that is impressive.

The battery life score could be just a better video hardware decoder.

Notebookcheck rated it 85% on the XPS which is pretty mediocre.

Considering how low the clocks look to be I wonder what the ipc comparison looks like.
It's not like Intel is just rehashing Skylake anymore.

Regarding battery: This 41% is a little bit misleading, in real life it wont be like that.
try to test office work/web browsing with chrome and opening and closing the browser and watch Inte's Turbo boost going over 45W each time and then compare same normal laptop usage on AMD and then show me if the Gap is so big.
[Currently using 8250U notebook].
