A member from dpreview wrote: 4K videos play smoothly on all current-generation Intel chips using Windows Media Player on Windows 8.1; this includes Atom processors and Celeron on up. How do I know? I tested this on just about every laptop, desktop and Windows tablet on display at BestBuy using 4K 100Mbps+ XAVC S videos on my usb stick. I regularly play and edit 4K video on my $249 Asus laptop with a Celeron processor with no problem (ignoring loooong rendering times). And, no, that is not my main computer :).
