That's pretty nicely done! I read the description earlier on about the three matte and one glossy surfaces. I noticed one earlier for the Xbox One as well.
Jonathan Blow and Cliffy B pretty much confirms that sony ram reserve is way less than MS at least right now. I would say 1GB is where its at right now on the PS4.

Not really. Blow starts off with the caveat "certain things havent been finalized" and says RAM reserve is "way higher", "I think" on Xbox.
Then Cliffy interjects "that's the one I keep hearing about". Sounding like he just reads the same internets we do.
So what Blow said is somewhat leading but not conclusive, what cliffy said means nothing. Overall still inconclusive.
Interesting though. Makes me come off the 3GB for PS4 thing just a bit.

Interesting, but his actual words were "that's way higher, I think, on the Xbox side then on the Sony side", in regards to OS memory reservation. He seems to strongly imply that's based on what he's heard. I get the impression Blow doesn't even have an XBO kit (that's my speculation based on his tone and what was stated). Otherwise he shouldn't have to "think" about it. I think I missed Bleszinski's comment at the time you mentioned. What did he say? Actually, never mind. This discussion is going in circles with vague statements vs extracted numbers.
True hard numbers will come out for the PS4 soon enough, as they have with the XBO, and regardless of any theoretical differences we'll have some great DF comparisons articles for multiplats and DF VS articles for 1st party titles.Interesting, but his actual words were "that's way higher, I think, on the Xbox side then on the Sony side", in regards to OS memory reservation.

true actually that doesn't prove anything regarding amount of ram on the ps4 side.

1GB is what Richard has heard too (from second hand sources).
out of curiosity what do we know about the aux port on the PS4? Is it possible an HDMI in adapter could be ran thru there? The 360 went thru some fundamental revisions over its life so I am wondering if PS4 version 1.0 could run HDMI in thru the aux port and later revisions might have HDMI in as part of the MB layout if that functionality proves to be important.
We know it's there for the camera.
Correct its there for the camera, which suggest it can transfer data at a fairly decent clip, I guess the question is could an encrypted HDCP HDMI signal be ran thru that port by way of an adapter...
If its based of USB 2.0 or 3.0 we already have converters available for that spec which are pretty cheap.
Depending on the amount of bandwidth needed for each it might be possible to piggyback both signals thru that port at the same time.
Doesn't make any sense as he's working on a PS4 dev kit. Sure, he couldn't but speculate on Xbox-One Ram partition, but that's not the case for the plateform that will be hosting his next game. :smile:
Here, whem he says this :
Common sense would dictate that OS RAM on PS4 couldn't be of 3 GB. If he thinks Xbox requirements are way higher, what would the Xbox OS dedicated RAM amount to? 5 0r 6 GB?
Feel free to correct me...
So according to this interview (in Japanese), Shuhei says they've already decided on how much RAM they're going to dedicate to the OS, and devs have been informed about it.
He also says they have no plans to disclose that information.

Given that they allegedly started development of the PS4 with a total of 2GB of RAM in mind, 1GB of reserved memory seems PLENTY (even a 1GB/3GB split would have been really generous to the background system stuff). They need to make provisions for future system capabilities, of course. But still.
The planned OS and background stuff won't suddenly take up more RAM space just because they doubled their system RAM to 8GB in a last-minute push ... so I really don't see them reserving more than 1GB (if they actually decided to reserve that MUCH)

Once they decided to put in 8GBs, they could revise what the OS would do and set aside more RAM. Or even just set aside more RAM and mull it over in the coming year or two, seeing what changes there are in the space and how to accommodate them.

Yes, of course. But is it probable that they changed their vision for the console as fundamentally as to require more than 1GB? What kind of background services (apart from having three different operating systems that run in parallel) would eat up that much space?
The best point you made, though, is that they can always reduce the amount of reserved RAM during the console's life cycle, while taking away RAM from games that have already been relased is practically impossible. So yeah. But I still think 2GB of reserved RAM would be a really, really much.
On a fundamental level, HDMI is much higher bandwidth than USB3. 4k video needs nearly 20Gbit/s. Even if you restrict to just full-HD it's still nearly 3Gbit/s in raw form without counting whatever HDMI protocol may add, and there would be additional overhead on top of that for transmission across USB interface.
In any case, what do yo need HDMI in for, seriously? It's a needless, BS feature on a console. Get a receiver if you require switching between several video inputs.
