First PS4 Hardware Revision Quietly Released in Japan

[Sharkyx1]

 

Almost two years into the PS4's lifecycle, Sony has updated the console with a substantial revision that is not only cheaper to produce, but is also quieter and considerably more power-efficient. The new CUH-1200 revision is currently available only in Japan so unfortunately we can't test it directly, but much of the analysis we'd like to carry out has already been done by the Pocket News blog, and the results are fascinating.

Let's talk about the physical make-up of the machine first. The changes extend way beyond the removal of the glossy plastics and a re-arrangement of the existing rear ports on the unit's exterior. On the inside, there's a new, smaller motherboard with a series of changes. Taking centre-stage is a reconfiguration of the GDDR5 memory set-up. Earlier incarnations of the PS4 used a considerable 16 memory modules to provide the 8GB complement - the new CUH-1200 makes use of double-density Samsung modules to halve that to just eight, which should reduce energy consumption significantly.

 

 

The main processor within PS4 has received a new designation, perhaps suggesting some kind of change to its design, but its physical dimensions remain the same, confirming that it is still a 28nm chip. There remains the possibility that Sony may have moved onto a more efficient iteration of the 28nm process, but our gut feeling is that it's still the same chip at its core.

 

And that's where the new CUH-1200 model really comes into its own. According to Pocket News's metrics, standby power is anything from 30 to 50 per cent lower (depending on mode) compared to the launch unit, while the main menu is around 11 per cent more efficient. Perhaps not surprisingly, the biggest gain comes during gameplay, where the launch unit draws 148.6W, while CUH-1200 brings that down to 122W - that's an 18 per cent drop, and actually brings PS4 power consumption down to the same approximate level as Xbox One.

 

So new PS4 reviision, double density ram, goodbye shiny plastic, lower power consumption and noise, probably some under the hood bug fixes too. I'd like to try to sell my 1000 for a new one, but it has PT so i'll probably keep it as long as i can. they shrunk the mobo a lot as the CPU is now inline with the USBs. Wonder why they wouldn't keep the memory on the face so it could be actively cooled, but i guess im no engineer at sony

Damn. I've had mine less than a year. I just wished I didn't miss PT.

I would like to see a passively cooled ps4,but it would be too bulky ;(

Looks nice. Me likey.

And extremely impractical, since a lot of people probably shove these in a hole with very little to no airflow.

Yeah like the other post says its probably not very practical, the PS4 uses about as much power as a 270X and you don't see to many passive 270s, the 750ti uses less than half the power

 

The other problem would be that it would need exposed fins, which aren't going to be loved by consumers and consistent air flow, plus the PS4 already likely runs quite warm

Well fair enough it's not practical.. but possible
