Sinclair replied that, “We are using a lot of the memory, but because of texture streaming, we have plenty to spare! That’s a good thing, it gives us options that we never thought we’d have before, and it opens up possibilities for extra detail and video streaming. The unified memory is part of what makes the console so great to develop on. You can use threads to generate textures and graphics assets.

“You can use the GPU to process physics and effects data. It’s key in shipping a console that is great early in the cycle while leaving the ceiling quite high for hybrid computing techniques in the future.”

We also asked a bit about Titanfall since, well, it’s another mech game with soldiers that wall-run and perform parkour. Especially since that game will be exclusive to Microsoft’s Xbox One and Xbox 360 (along with PC) while Warframe will be PlayStation 4-exclusive. He replied, “Huh? What’s TitanFall? Kidding. Saw TitanFall at E3 and it looks amazing and we saw a lot of the parkour stuff we have for our Space Ninjas in there…

“I expect TitanFall to just raise the competitive bar and push us further to keep our fans engaged. That said, without knowing a lot of about the game, Warframe is focused on PvE and Coop. It’s a shooter/MMO blend with crafting and dojo building. We update our game at a staggering pace, which combined with our procedural level generations, keeps the game fresh on a weekly basis. I don’t think it hurts that we’re free either.”

Warframe’s release date for PlayStation 4 is currently to be announced.

However, Vblank Entertainment boss and confirmed PS4 dev Brian Provinciano took to Twitter to state that the rumours were false and ridiculous.

@mrnray It's absolutely false. Absolutely ridiculous.

Provinciano did not confirm how much RAM was in the system. Considering how Microsoft was skewered for stating the Xbox One would allocate 3 GB to its OS, we can see how this would affect Sony’s projections of being more powerful (though make no mistake – 4.5 GB DDR5 RAM is far superior to 5 GB DDR3 RAM).

On NeoGAF, industry insider Thuway provided his own numbers, stating that the PS4 actualyl reserves up to 6 GB of RAM for games and 2 GB for the OS. “There are games in development that are using 6 GB of RAM,” he stated in an update. Other insiders such as BruceLeeRoy and forum admin Kagari corroborated this report. What is the truth? Stay tuned as the story develops.

However, it seems that guaranteed baseline RAM is 4.5 GB dedicated specifically to games while 1 GB, which is used for the OS, is classified as “flexible” memory which can also be utilized for development. And that’s if the OS isn’t doing anything with it at the time.

The current “Game Memory Budget Mode” on dev kits allows for normal and large modes in the debug settings. The former allows 4.5 GB off the bat, while the latter allows for 5.25 GB but is available only for application development. Either way you look at it, the Xbox One and PS4 are a lot more similar than it first seemed. Nonetheless, in terms of GPU power and type of RAM, the PS4 can still claim to be ahead of the Xbox One…or can it?

Given that it was a source that revealed all and not an official announcement or confirmation based on public testing of the console, there’s still room to be skeptical. Stay tuned for more details.
