Can first-gen mobile Intel Core CPUs play YT videos smoothly at 1080p 60FPS?

I was looking for older laptops, and can't help but wonder whether CPUs as old as the first gen Nehalem CPUs could play YT videos at 1080p 60FPS, since they are about 9 years old today.
Would YT play nice with the old iGPUs? My guess is no.

 

First lets clarify that you're talking about Core i, and not the older Core (Core Duo, Core 2 Duo...). Not everyone knows what Nehalem is.

I just tried to play it on my parents Core 2 Duo E8400 (3 GHz) desktop, which is older than the Arrandale you're talking about, and I couldn't see any stuttering.
It utilized about 85 % the CPU tho, so lower clocked CPU's may not be capable to do it, even if it's a generation newer.
I have no clue how much the GPU comes in to play here, but the first Core i CPU's had a much better GPU than the one I tested.

 

I think video playback is alot different then Gaming at 1080p 60fps we need to separate these two parts. First what links of the video playback in question? That would allow others to test what your asking as well. I played YT on a Dell 1525 without issue loaded with W10 and T8100 cpu. Video playback is less intensive on the On-Board GPU but it depends on your Internet speed as well. That is how I see it in this question.

 

Never had any issues while playing content in 1080p/60fps, but with my i7 920XM and 940XM never had any issues. With stock M15XR2 config there was a lot of stutter, but once full potential was achieved then it works like a charm.

 

All depends on the codec being used. Your GPU may not support newer 1080P videos encoded in H265, VP8, or VP9 (most probably not if we are talking a Nehalem system). H264 should be handled by the GPU no problem.
