Exactly the opposite. Terrible and choppy. You see, all U-series i3 mobile CPUs have only 2 physical CPU cores - woefully inadequate for any prosumer-level video editing program these days. That config is much more likely to be extremely frustrating than good or smooth.

And that is all because in addition to the woeful-by-current-standards CPU performance, that planned laptop has too little total system RAM and no discrete GPU (it relies solely on the RAM-stealing integrated graphics). Just with the default Windows 10 configuration, only 3.5 GB (3.5 Go) of total system RAM would be available for the apps. But Premiere Pro requires a minimum of 8 GB (8 Go) of free, unused system RAM to avoid choking under pressure. For that planned PC, you would have needed 16 GB (16 Go) or more installed RAM just to not buckle under pressure, let alone run "good and smooth."
