so is there anything in this thread that still makes sense with the new leaks out?

That is old.
Did they do work on the Vita also? Those are common features on wifi / bluetooth chips, I could see them throwing them in just in case Sony wanted it. I wouldn't be surprised if the ps3 has fm and gps, with those parts of the chip just disabled or ignored by the OS.

I'm also interested in this.
Which part?
Devs are getting close to final specs dev kits, hence why we're getting more leaks?
Edit: also supports the rumour that orbis will be announced at an event before e3.

I like this one too! Searched it, seems like a random photo for engadget's 2007 interview with Tretton and Hirai. But it has its special... mood.

512 bit RAM bus. I guess that would be the case if they used DDR3.
The only source I can find on that on the entire internet is a GAF post so it's a dubious rumor at best. There's no reason to entirely drop a key feature from the engine since it'll at least be able to be done on PCs.

About 100%.
Right. I kept looking for it but found nothing.
Oh really.

I'm still not convinced. I'm erring toward DDR3/4 stacked.

So if they use DDR3 then cost for RAM will go up in the near future right?
I ask since there was a rumour floating around very late last year (around Nov or Dec) about how Sony had shipped two dev kits with 8GB and 16GB RAM. Conventional wisdom would suggest dev kits contain anywhere between 1.5 to 2 times the amount of RAM found in retail version of a console. As such, the 8GB system may have been simulating the final 3.5GB (Rumour: 512MB reserved for OS) GDDR5 package. But what about the 16GB one? Unless, the DDR3 equivalent of a dev kit for 3.5GB GDDR5 system is best done with 16GB, it spawns the question, "why".

I don't think so. I just think it's in the dev kit. GDDR5 is expensive. Why not go with another expensive route that has potential for price drops in the future? Stacked DDR4.
Yeah most chips will have the gamut integrated on them, however there are no antennas hooked up ... so they'd be useless even if the OS did see them.

There is no difference what you use regarding the width of the bus. The only difference is the number of RAM chips you'll need.
There have been recent rumours here suggesting that DDR4 (the version which will outperform DDR3) will not be ready for large scale product, and hence, stacking. Chances of stacking DDR3 however, are more likely.
The odds would logically follow this way (logical speculation is still speculation):
Dev kits currently have GDDR5 to simulate final hardware
It is becoming clear that sony is betting the farm on stacking
Should this be successful final hardware would likely have DDR3/4 on a wide bus
Should it not, well then sony is in a spot of bother but perhaps they have some sort of contingency plan/design which incorporates GDDR5
Problem is very few companies have the money and manpower to develop a complete contingency plan so at this stage i'm leaning towards there being stacked DDR3/4 thus alleviating any need for GDDR5

Not just expensive but has high power usage compared to DDR4. Not sure of the difference, but would guess 4GB DDR4= ~10W 4GB GDDR5= ~30W+?

I'm far from a technical expert but sometimes when I read people talking about resolution or framerate it becomes obvious to even me that they have no clue what they're talking about. Resource allocation of this sort has nothing to do with hardware limitations. If the system was more powerful the dev would be just as likely to add more content or effects before upping the resolution.

Companies are looking for big tech players to purchase large quantities of the RAM (not just plain ram, but 3D stacked) to boost the production. Several companies are ready to go, they just need a big player. Sony can be that player.
DDR4 stacked can reach AND exceed GDDR5. Using less power as well.
Sony sauce simulator?
Maybe not added just in case so much as had trouble sourcing large volumes of wifi/bt chips that didn't have those features. It's based on an old discussion with a Sony insider about PS3 build costs. About all I remember is that getting commodity chips with fewer features can sometimes cost more than simply grabbing the popular, high volume chips and disabling the stuff you don't want. The example used was the extra functions on common wifi/bt chips.Do you really think thats how it works? They just throw in stuff just in case?
And yes, I can see whoever is integrating the combo chip pimping all the features it has in his presentation, even if he knows half will be ignored.

doesn't really matter what kind of memory it is, as long as the bandwidth is there.
It would... but less than kinect2 in every X720 SKU.

AFAIK, that isn't known yet. Though if Kinect only hardware is in every Durango, I can see why some might think it.

I'm guessing 8GB 68GB/s DDR isn't cheap either. Current high end desktop PCs are up to around 40GB/s. But I'm guessing the prices of DDR will drop fast, while GDDR5 won't.

Wildcard berths that can't beat teams without a winning record should have homefield advantage
Source? Because I can't possibly see how we have any knowledge of this.
it is different to use or not to use functions of wifi chip and to add two extra chips like FM and GPS, which cost more... probably cost saving over $100mil over the life of console
You can only say that if you assume the current (old?) dev kits we have information on are indicative of final hardware - which is more realistically not the case
We've long been at and surpassed the point where things as simple as FM recievers and GPS chips are on-die... that saving estimate is ridiculous

I suspect too. I think it may a false hype by someone just want to watch the world burn.
This is such a retarded argument. First of all, the Vita is home to the best looking portable games you can get.
Going by your logic, the PS3 and 360 are bad hardware, as 99% of their games don't run at native HDTV resolutions (1,366x768 or 1920x1080). And you conveniently ignore all the games (first party and otherwise) that do run at native res. Wipeout, VT4, EDF and so on.
Anyway, no one apart from pixel counters give a shit. Overall IQ (frame rate, AA, effects) is far more important, and the Vita has shown from day one that it's more than capable. Racing around Sol in Wipeout still makes my balls tingle.

I wonder how the ram choice will affect the rest of the system. GDDR5 will draw more power than stacked DDR4, could we even see the CPU and GPU clocks altered based on the eventual power draw of the ram?
I doubt it. Jaguar very little energy. They may also have decided to go with GDDR5 after switching from Steamroller since there will be less of a CPU power draw and less heat.

I know old documents state that Sony is big on the memory stacking, like in the Vita. I'm sure the DDR5 is the speed they intend in the final machine. So I'm assuming it will be a stacked memory that's capable of DDR5 speed.
My understanding is that fm and gps are those extra functions. Thanks to the mobile industry, it's hard to find wifi and bt combo chips that don't also have fm and gps, which is why those features are randomly popping up in a presentation from a contractor in regards to game consoles.
Kun Aguero

I'd forgot they'd planned to go with Steamroller early on, so it sort of balances out with GDDR5 as you say, but if they can get stacked ram in time, they should be well under their original tdp with Jaguar drawing a lot less power than Steamroller. Might give them some wiggle room to up the clocks if they want.
