One should also note that the x86 platform has taken on some SoC like structures over the years, with AMD as a driving force.
For example they lumped the memory controller onto the CPU die with the Athlon 64, and then a GPU on their A series.

I've never had an APU but on paper they sound really nice. Intel probably has similar but you may have to be more careful picking your CPU because of market feature segregation.
I would check video drivers, DMA enabled on drives, excess ram or cpu usage by another process(es)
My 7 year old notebook (the one I retired already) had absolutely no problem with videos of this size.
