Can an Intel CPU with <=HD 61x transcode one 4k stream?

My Intel J4205 has an HD505. It can transcode 1080p HEVC -> H264 at about 7-8x real time (this rate is for 24-30fps content). 4K is four times as many pixels as 1080p. I don't have any 4K content, but assuming a linear performance progression that would mean the HD505 can probably manage 1.75-2x real time transcodes of 4K content. Not sure how HDR and tone mapping would affect those numbers.

With the significantly higher TDP and GPU clock speed of the G4930 it should be able to comfortably do one transcode stream of 4K HDR HEVC. MAYBE two.
