The major problem is power consumption/battery technology and without a grand leap forwards in those areas it's probably not a good idea. With 7nm manufacturing it might be possible to get consumption (including additional components a HH needs, like screen/speakers etc) to about 50W (the PS4 Slim has a peak draw of ~90W and it's APU is made with the 16nm process). In comparison the Switch is at ~9W max consumption in hh mode and already is critized quite a bit for only offering a bit more then 2h battery life in demanding games. A makeshift solution might be to include ~30min battery life in the hypothetical PS4portable itself and shipping it with a power bank that you can wear on your body without too much of a hassle, but I doubt the public would be all too receptive of that. |
So I guess once we get to 4-5nm technology ... and that's probably the limit. At least according to SIA, by 2021, it won't be economically efficient to reduce the size of silicon transistors any further. It's kind of scary to think that with the current battery and silicon technology, PS4 might be the very best we could do with portable consoles.
