The Surface 3 was a 'sealed' fanless tablet, like a phone or an iPad, but it had an Atom chip. The Surface Pro 4 had a fanless Core m3 model, but there was venting all around the perimeter of the device (not exactly waterproof haha) and people rightly pointed out that iPads don't have vents at all. But the Surface Go that was just announced has a Pentium Gold 4415Y and it is fanless and sealed, just like an iPad. This is a first! I didn't think this was possible for 14nm. It's also not that large a device, a 10" display at 3:2 aspect ratio. It's pretty impressive especially when you consider it's running full Windows. Congrats to Intel on a small milestone, they've come a long way.
