You couldn't be anymore wrong! Console OS's are very much like a PC OS... In the 8th console generation.
The Xbox One OS is based upon the Windows 10 kernel and leverages PC virtualization technologies (For it's other OS's) in conjunction with PC-like API's such as Direct X 12.

The Playstation 4's operating system is *nix derived.

Of course they have a different UI skins and have some specialized functionality... But the Operating Systems themselves are very much based on PC technology these days... 

No they are not. And I am not referring to underlying architecture..... yes XB1 is windows based and PS4 is FreeBSD based..... but they are not like a PC OS by function. Especially with regards t the PS4. We can argue that everything is "based on PC technology" and you will be right, but that is more to do with "PC technology" already having everything and less to do with specific use case scenarios.

Hell even android can be said to be based on PC technolgy cause technically its a linux kernel. And we have PCs that run FreeBSD OS and what nt which is also where apples Mac OS is derived from.

Point though is that the PS4 OS is not like a windows OS r a Mac OS or even an android OS. Its more limited..... that could be by design or whatever but its not like you can just download exel or powerpoint and use it on your PS4. So if the PS4 S even has the underlying APIs to make those work then its just a waste of resources since it doesnt need any of that.

Looking purely at whats capable with a PS4..... there is no concieveable reason (besides piss poor software design) as to why its OS should be taking up as much as 3GB of RAM and still be more laggy and slower than an android phone with 2GB of (slower) RAM which also happens to be capable of so much more.

Care to provide some examples on said redundancy?


That is generally handled by the drivers and API's.
Also... One of the issues during Vista's launch was actually due to the duplication of data in the memory pools... Especially for the Integrated Graphics and System Memory pools.

Starting with WDDM 1.1 that duplication was abolished... The PC does get more efficient as time goes on... It's not just consoles they get optimizations and performance tweaks.

See here: https://docs.microsoft.com/en-us/windows-hardware/drivers/display/video-memory-management-and-gpu-scheduling

In short though... My Ryzen 2700u notebook with 8GB of total ram games at similar quality settings to an Xbox One... So the consoles really aren't doing more with less memory.

I have pointed out the the whole copying data in multiple places thing. And I am sorry but when talking about systems that have a CPU and GPU with separate  pools of RAM unless there is something I am missing, or unless the CPU has direct access to  VRAM... Data shared between the CPU and GPU in a PC has t have that data be in both pools of RAM This is even considered to be one f the primary advantages of having a system with unified RAM.

And I am saying they should because they aren't doing anywhere as much as any number of other OSs out there. They are required to do significantly less... and yet even with their 3GB ram allotment they can`t even do the little they have to do very little quickly. 

I mean I have an android TV box with a an amolgic arm cpu and a mali GPU with 3GB of RAM and 32GB of expandable storage that runs rings around the PS4 and XB1 when its comes to OS functionality.
