Playstation 5 & Xbox Two are going to be Monsters!

Not talking about same HW, but comparable... but thanks for the explanation.

I'm not talking about same hardware either, but talking about comparable hardware.

The issue is that we are talking consoles here.

You either have the exact same hardware (albeit smaller if built on a smaller fabrication process) or you have something that can emulate the hardware, which usually requires you have something that is significantly more powerful.

And if you want this thing to support all the games on the PS4 now, then you have 3 options.

 

1. the devs are going to go and do some extensive work on all their games to make them support some new exotic hardware
2. you brute force your way through it by having much much much more powerful hardware in the handheld than whats in the PS4 now so you can emulate it so the devs won't have to do anything
3. you basically take the APU, memory config (size and bandwith) that we have in the PS4slim today and somehow get all that to fit in something about the size of the NS. with a power draw no more than 15-17W unless you want to play untethered for 30mins at a time.
   
   I'm sorry, but thats just impossible in 2-3yrs when 7/10nm chipsenter the market. Maybe in 2023-2025 when we may have 3/4nm chips.

 

Man you got me wrong.

I'm not talking about making a PS4 Portable. I'm talking about making a PS5 Portable (that sure could have power similar to PS4), but that both HW the console and the hibrid (7 or 10") could run the same game with compromise. I got some answer on the hard part for disc based and also that the scalability wouldn't be easy as turn the dial, but still not that it is impossible.

Well can you please explain why or by how much in 2020 we couldn't have a PS4-like portable?

In 2020 it could be possible.
But it's not currently possible with today's technology, we can get "close enough" though.

The biggest issue is going to be memory bandwidth... Mobile devices typically need to use low-voltage DDR, LPDDR4 isn't scaling high enough in clockrates to be a viable alternative to the GDDR5 in the Playstation 4 just yet.

AMD and nVidia are slowly making use/getting around limited bandwidth via technologies like Delta Colour Compression and Tiled Rasterization with better culling... But there is still 100GB/s or more of bandwidth to make up for.

Things might change once LPDDR5 becomes common place.

for a 720p or 1080p display on a 7-10" hybrid would you agree that it would be possible to have this version of the PS5 (sure with lot of compromise and perhaps power level of PS4)? Sure there are some technical burdens today, but designing from ground up I don't think it would be impossible (but it could ne uninteresting).
