Predict: The Next Generation Console Tech

I am thinking most of the 3GB is dedicated towards third party apps that needs to be running concurrently with games, i.e. dvr, ticker overlays, realtime video recording etc. In that case I don't think we'll ever see the 3GB figure getting shrunk by more than 25% max.

 

I can say even you open 10 apps in same time you still don't need 2GB RAM,plus even Win8 use less RAM than Win7,how can MS go back to vista level OS in future
They're software company,not Nintendo

 

Almost zero chance of system reservation shrinking in an xbox product.

 

Xbox 360 OS use 32Mb, now Xbox 720 OS will use 10x ram?

 

There will be no virtual memory on consoles.

 

You mean 100x (3 GB)

 

I guess we're hot.

But your right. Microsoft carefully planned out their 32MB reservation for what they would use it for in the future, Sony by comparison was all over the place and they had to cut features for that.

I guess they are planning some pretty big stuff OS wise.

 

Ops! you're right.

100x is a lot, 512MB-1GB is what I'm expecting, with room for future features.

 

Agreed, it's unlikely. It might not work too poorly if they stuck some on a flash drive or something though, but we need that instant app switching.

 

Going back to the last major leak/rumour about the Orbis. http://www.vg247.com/2012/11/01/ps4_details_playstation_4/

I'm wondering why dev-kits would have either 8GB or 16GB of ram. Would it be plausible to have two different sorts of ram in early dev-kits?

Perhaps the 16GB is ddr3 while the 8GB is faster ram, or more customised, with Sony wanting feedback from devs (especially first party) as to the preferable option?

 

It doesn't matter,it still won't use 3GB(or even 2GB) in OS

 

Maybe 16GB just incase they're upgrading to 8GB in the final console?

 

Yes, I'm wondering if Sony are worried that MS will have 8GB, and they are unsure if to match them or go with a smaller pool of faster ram.

 

No, it will be either 4 or 8, not 8 and 16. 4GB GDDR5 or 8GB DDR3 or 4.

 

Virtual memory is the thing that gives each process a virtual address space, maybe starting at zero, which appears continuous and with no pages from other processes in the way. Processes are actually well isolated from each other, "sandboxed", probably, for security reasons.

If you specifically mean "no swapping", of course I can only agree with you. You're more likely to have a memory excedent, which would be used as disk cache.

 

I agree, MS shrunk a fully functioning Windows 8 OS ram footprint significantly from Windows 7, I can't see a jump from 32mb to 3GB without a better reason than "dvr and apps".

 

With the conformation that Durango will only have 5GB of slow, low bandwidth main memory available for games is it safe to assume that there will be a large amount of ESRAM on the GPU die?

 

Can "this":

Be enough powerful for today PC (steam) games?

 

Well we can already assume that durango will have EDRAM, Microsoft has benefited wildly from that this gen. Of course Sony went with something completely different for PS3 after PS2's run in with EDRAM, but in that case they were trying something completely new, this is still a relatively normal set up
