Well that was mind blowing.

Secret sauce confirmed here ?

Are you kidding me? PS4 8GB GDDR5 RAM + PS3's RAM Equivalent?



Predictions for end of 2014:

PSP: 82.9M
DS: 154.1M
PS3: 86.1M
XB360: 82.7M
Wii: 100.9M
Wii U: 8.9M
PS4: 18.5M
Xbone: 8.5M
3DS: 51.6M
Vita: 10.7M

3DS Friend Code: 0533 - 6146 - 0418
PSN ID: atylerman5

Will that do much?



Interesting. Unlikely I know, but I wonder if any devs will experiment with using this memory and the PS4's secondary processor to help make their games look better - I think Naughty Dog might have done something similar when they made the Jak and Daxter games on PS2 where they used the built in PS1 chips to improve the performance. I'm fully prepared to be proved wrong on that though

for what is this used?

Bet With Zero: He says WiiU and XB1 gap will be higher than 1.9M by end of 2014, i say it will grow smaller or vanish. 

Bet with Pezus: i win if Watch dogs sells more on PS3+360  than on next gen PS4 + Xbox One. winner gets 1 month sig control

Bet With JoeTheBro: He says WiiU in Jan 2013 > XB1 Jan 2014, i say the opposite.

Isn't that for the UI ?

 

It is the memory used by the ARM background processor.

What if sony made a new model without retrocompatibility ?

I wouldn't have taken the risk



 

- Samsung K4B2G1646E-BCK0 2Gb DDR3 SDRAM = 256 MB DDR3 memory
- Macronix MX25L25635FMI 256Mb Serial Flash Memory = 32MB SECURE Serial Flash Memory

@ boom, this exceeds what's needed for background downloading & Playready DRM, DLNA client/server and IPTV player. Speculation is that the excess can be used for the 15 minute loop @ 720P (h.264 compressed) and my view that it can also be used for a RVU video loop and cache for DVR to reduce the on time for the Hard Disk.

Then PS4 software credits include Mono, Mono VM, Lua, Cairo, Webkit, Microsoft IP which includes Playready DRM and more.......

Playstation mobile requires Mono and Java, PS Home requires Lua, Webkit and Cairo

Why this exact number? Is it to emulate PS3 games via Gaikai later or something?
