VGLeaks: PlayStation 4 "Orbis" Roadmap

Look at Sony's line of embedded products, they definitely have more experience building OS' to the bare metal and thus more restricted environments. I think 4GB of quicker ram is better, what's the point of filling 8GB if you can't flush out the assets quickly enough - so you probably have a higher percentage of stagnation for more memory pages. People compare these systems to PC's but they're still more comparable to embedded systems, so memory setup of these systems are more flexible than memory setups on PCs for instance.

certainly Sony should be more efficient in an 'embedded systems' type OS Vs MS just slapping windows 8 on there. But who knows?

Is this a joke?

Shitloads of things on the planet run on MS embedded systems from Ski-lifts, to scanners to ordering systems. MS has way more knowledge of OS design... some of the people working for them are legends in OS design (they might now have run to Google ofc :)
 
Morrowind (Xbox) -> Skyrim (360) = 8x jump in RAM

512MB->4GB = 8x jump in RAM

Skyrim Consoles = 0.5GB

Skyrim PC min requirement = 2.5GB RAM

=> 5x inflation in memory requirements on Bethesda's games between PC and console

If next gen elder scrolls is to be playable on more than a handful of player's PCs in the next two or three years, they cannot really target more than 8GB on the minimum end in PC land. They're probably more likely to target 4-5GB IMO.

In any of those scenarios (4-5GB or 8-10GB), even with a significant improvement in their memory usage on PCs, a 4GB console would be fine. And would be fine also from a historical 'next gen leap' POV for Elder Scrolls.

in this thread, operating system overhead scales linearly
 
where did they say THAT? And by the way its easy to see that ps3 skyrim's problems are a result of the mem pool config of the console.
How is it "easy" exactly? Skyrim's problems are the result of the engine. Plenty of other games have existed on PS3 just fine - they get the exact same resources Bethesda got with Skyrim.

"The way our dynamic stuff and our scripting works, it's obvious it gets in situations where it taxes the PS3," Howard told Kotaku. "And we felt we had a lot of it under control. But for certain users it literally depends on how they play the game, varied over a hundred hours... It's literally the things you've done in what order and what's running."


honestly, If the xbox really has 8 GB, sony has to catch up. I do not trust the "faster ram" fairytale. Years of PC gaming told me that more ram is indefinitely more valueable then fast ram.
What are you talking about? Go and read the various PS4 threads. You can "not trust the fairytale" if you want, I'll instead take on board the opinions of people who know what they're talking about with regards to memory and have explained how each memory configuration can be beneficial.
 
Is GDDR ram available on its own yet? I can only find graphics cards with it.

It's only on graphic cards... I don't think PC will ever use it as main ram, it's been on the market for quite some time now, maybe because is expansive/hot?
Also, DDR4 should be on the market soon as far as I know.

In reference to the 'PC multiplier' - sure, it doesn't. But I don't think that affects my core point. Even if the gap in 'memory efficiency' narrows significantly vs the Skyrim case, I think it's unlikely a 4GB console will have problems. If next-gen Elder Scrolls targeted (say) 6GB in a console context, the likely min PC requirements would be well beyond the avg and that jump in requirement would be larger than between the last generations of elder scrolls.

I think people are looking at numbers and if they don't match they think there's a problem.

2GB would problematic. I doubt developers would be nearly as strongly-opinionated, negatively, about 4GB. 8GB is nice but I very much doubt it represents the threshold required by developers.

A CPU doesn't really need that amount of bandwidth. Just compare the high end i7s (LGA1366/2011) CPUs to the ones that only use dual channel. The extra bandwidth only adds performance in certain cases. Iirc, CPUs benefit more from lower latency memory than having more bandwidth. GDDR5 has way more latency compared to DDR3, but that gets compensated by putting the memory chips right next to the GPU.

It's not supported by PC chipsets and processors. Besides CPUs don't get much faster with faster RAM nowadays anyways, like going to 2100MHz RAM from 1600 will only get you a few more percentage points in most applications. So GDDR wouldn't help processors out much.

Some integrated GPUs (AMDs APUs) would benefit from faster bandwidth, but at that point you may as well have a discreet card.
 
So is it not possible that along with the 4GB GDDR5 that developers can see there is also 1-2GB of invisible DDR3 RAM reserved for OS functions that developers can't see that only SCE can get at for the OS.

4GB GDDR5 is a lot, but it would be a waste to use that for OS functions and as long as the OS RAM was locked out for development purposes then including it would be pretty cheap. DRAM is around $3/GB at wholesale price bought in bulk so including 2GB or even just 1GB for OS and background functions would be plenty to ensure Sony don't fall behind for OS functions.

Or they can dynamically scale their OS (which they are doing with Vita) so when running during the game decrease OS overload to minimum just for message stuff and then come back full scale when you press PS button.

That's totally feasible, too.

this would compliment their patent on dynamically switching between two different gpus no?

Years of PC gaming didn't teach you much then. Did you ever notice how when the video card price went up the more high end the memory got? For the longest time most GPUs had 1GB RAM, but they could use 128-bit DDR3 up to 384-bit GDDR5. There is a very good reason card makers would use that higher bandwidth memory.

My GTX 670 kicks major ass (1080P 60fps), it has 256-bit GDDR5 for 192GB/s. Now go down the range to a 630 with 128-bit DDR3 at 29GB/s. Why not put the same DDR3 on the 670 and save money? Hell it is so cheap, put 8GB on the card!

I'll leave the reason as an exercise for the student.
 
Sony will just call theirs "HD memory" or "Blu-RAM" or "Memoriocity"

original


:p

I expect fluid switching between games and apps if the PS4 has GDDR5 RAM.

It really depends on what they had in mind with the end-product. MS slapping Win8 onto there makes sense to have 8GB of slower ram - the architecture has a constant overhead. PS4 may likely have more limited concurrent OS functionality but will be designed to push their new technologies - 4K etc. I think they're both going towards two different approaches.
 
Finally! My hype is over 9000!

@Evolution, after the latest rumors, I'm not so sure we can expect 2 GPUs. They mention one big APU.


Who said this and how is this good? Sounds like they are going for money savings, nextbox will blow PS4 out like tornado if this continues

why would having windows 8 = large memory footprint? Windows 8 is designed to be light and fast. Even desktop windows 7 has a mem footprint of 1G. I'm pretty sure 720 would use just the kernel, stripped of everything but the bare essentials.

ed, sauce
 
Not when you buy it by the millions. MS and Sony get massive discounts because of the huge orders that they do.
I don't doubt they're using it, but it will still be very expensive.

I do doubt that the memory being reserved in 360N or PS3N is for traditional apps. There's more to it than that.
 
Dynamicaly scaling the OS can work, but it depends on how fast the RAM can be filled up. If the OS goes from 128MB (Game Mode) into, for example, 512MB - 768MB, that would mean they need to write the extra stuff into RAM, which would take time depending on whether the OS is in the HDD or flash memory. RAM bandwith doesn't really mean much here, since it's not the bottleneck.
 
I think it is trying to say that people reporting underwhelming specs are just talking about the "system block" instead of the "app block" that will be used for games. You'll have to forgive me though, as I'm not up on my gaf sources and I don't know the significance of sweetvar26 quoting it
 
So what was that post that sweetvar quoted saying? I tried to makes heads or tails of it and all I got out of it was PS4>Durango unless I'm looking at it wrong.
I got something like "PS4 > Durango is true if Durango = this, but it also has this too"... or something.

Sony filed a patent for a chip with dual GPUs just a month ago. Not a single one of these latest rumors addresses this patent. Skeptics can argue that the chip can be for any of Sony's product lines (laptops, TVs) but I have a hunch Sony has released misinformation to gloss over this patent. Sony's new 4K TV is the only other plausible product for use of this patent, but I believe its for PS4.

We're confusing Durango specs. The current Durango specs being quoted are a jumbled conglomeration of different sub-systems. In 'layman speak' the 'Full Durango™' is something closer to 3TF.

Which sounds like lunacy. I'm just wondering why sweetvar quoted it -_-

Taking a very simplistic approach:

Well, essentially it's saying that Durango, as in the final console that we consider to be the Next gen Xbox is made of 2 Blocks. There will be 2 versions of Xbox, like it has been rumored before, and the one that is meant to be used as a set up box for cable companies will be packing just 1 block. The Xbox that will be sold for core gaming, will pack the 2 blocks combined.

And apparently, the numbers we have from the rumors that are out there, are mixing parts of Block 1 with Block 2 instead of the whole picture.

Could it be that the "3TF" part accounts for the cloud computing plans of the "92821757-XBox-720-9-24-Checkpoint-Draft-1" leaked document from 2010? That proposition regards 2015, a 3TF machine (if that's even viable as a measure in a cloud context) could be a reasonable jump if Microsoft needs for some reason revitalize the format. It could perhaps be what Xbox LIVE was, when it launched, to the original Xbox.

Is there any chance that Sony would have developed it? Surely using traditional ram would be cheaper, even if thsy use more? I just don't understand why.
 
Who are these people and why do we care what they think? At this point the only people who know much are MS or Sony insiders (i.e. 1st party) and no one is an insider to both. 3rd party devs are still in the dark on final specs.
