Along with the 8GB of dedicated GDDR5 RAM, the PS4 has an extra 2Gb of DDR3 RAM, a system teardown by iFixIt has revealed. This extra 2Gb – that’s really 256MB, 2 Gigabit rather than 2 Gigabyte – is suspected to be used for background processes on the secondary processor.
So, while it’s not going to make your games run any better (though we suspect they’ll be just fine), it could be what allows background downloading and installing to take place.
If you think about it, that 256MB for the background processes is the same amount of RAM dedicated to the GPU on the PS3 – that just goes to show how much of a step up the PS4 is, and how future proof it could be.
The teardown shows each individual part of the system, and also reveals that the power supply is rated at an AC 100-240 volts, which means that it’s universal, and you can take your PS4 around the world providing you have the right adapter on the plug end.

Blimey!As a PSP, PS2 and PS3 owner, i’d gotten used to Sony scrimping on Ram when it came to hardware.
Lesson well learned there Sony.

Investigations into the APU shows there are 2 more compute units than Sony states (20 instead of 18). That’s an extra 128 stream processors.
They could be dead or redundent, but if they are inactive Sony could reactivate them with a patch which would boost GPU power by 10%.

I think its funny how your article exploits peoples lack of knowledge between bits and bytes. The average gamer would not have a clue that a byte is made up of 8 bits and that by using a small ‘b’ your are speaking about bits not bytes which are 8 times as abundant as a byte. Using the term “Extra 2Gb Of DDR3 RAM” is such a ploy.

Makes me feel good inside to critic articles..
But seriously yes I did because I think people shouldn’t be deceived and that I’d like to share my knowledge.
