It doesn't matter that it is barebones. It isn't necessarily using this memory. It's just what they reserved for future use. Once you give more memory to games, you can't take it back. It's what happened with the PS3: they gave too much memory to games and then were unable to implement party chat down the road.

It's not a lot off resources and easily on par with what PS4/X1 are doing. You could swap most of the memory used when gaming and give more of the memory to devs. But it would mean that everytime you tried to use the OS, it would have a delay of some seconds and probably feel slow for a while.

One of the things I hated on PS3 was how his OS became painfully slow when a game was open. You also couldn't even open the browser or do basic stuff without closing the game. The first thing I loved about PS4 was how fast the OS was with the game open, I could use the browser, change to Netflix, configure the system, open the store, everything was fluid. That's a good part of the experience, too.

I wasn't talking about ram usage though. I don't have anything against the OS using 25% of the power.

I was talking about the system being released without being finished.

the layout of the Tegra X1 cores is clustered switching (oldest big.little system), meaning that only the big or the little cores can be active at a time, because that's how they are wired to the caches

for that reason I think the little cores are deactivated at all times (= wasted silicon space) in the Switch, as the chip would've needed to be redesigned for all cores on the die to work at the same time and recent Switch die shots look very much identical to a stock TX1

I had the same question before, like pretty much all consoles, they dont give full resources to games, not like a general computing maching - computer.

The reason is most because if you allow using vitural address space and virtual memory for a console, it is actually less efficient. 

Implementation of Virtual address space and virtual memory in a computer is quiet "costly", but for a computer, it is designed to run "many" programs/processes at same time, because they are switching soooo frequently, the cost of using virtual address space alongside some kinda generic scheduling algorithm is relatively low comparing some other solutions. However, it is obvious not the case for a console, you will end up wasting CPU resource and swaping memory in to and out from disk inefficiently(this is a strong performs hit).

Also in order to translate addresses, you will need either a software translation solution or a hardware translation solution(like a MMU in a computer CPU).

Software solution is too slow and hardware solution consumes too much power(maybe).

And stablity and predicatablity are strong concerns for developing games on a console, as well. Giving games a fixed number of physical memory and CPU resources, I think, help a lot. 

Oh, I misunderstood your comment. I think it's clear it realy isn't finished and that they rushed it, probably due to Wii U's performance. It also has basically only one big game. Most Nintendo titles are scheduled to the second half of 2017. I think it was originally scheduled to launch in the Holidays, but they ended up releasing it early and doing a soft-launch.

The launch of Scorpio, plus the inevitable price-cuts for PS4 Pro, Slim and X1 S during the Holidays may also be a factor in this decision.

By promising you mean a million times worse? The video shows it looking absolutely horrible in comparison...Not sure of your point here,

But fragon quest graphically is a joke on both consoles, not a good comparison. Lets see horizon dawn on switch.

Ps4 is GDDR5

While I agree that you Dragon Quest is not really using the potential of the Play Station Four, bringing Horizon Dawn to picture makes even less sense.
I mean, we know that the power of both consoles are drasticaly different so trying to compare the graphics makes no sense what so ever.

At the end, the Switch is powerfull enough to bring something like the new Zelda which is fantastic (gameplay but also graphics). And in my oppinion this shows the 3 Cores + 3GB RAM is enough to be able to build some really good games on the system.
