PS4 power draw - 80W idle, 120W-140W gaming, max 45 Degrees Celsius exhaust
- Thread starter tipoo
- Start date
For reference:
(these measurements are at 1m)
So yeah, not super quiet. Definitely much better than a launch PS3, but not quiet.
How the fuck are these measurements made. Most of these are below the ambient noise of a normal room.

Enjoy playing BF4 on your netbook.
The wattage is what matters in terms of heat output. 140W is significantly less than a launch PS3.
So essentially that's mostly irrelevant.

I expected high watts for gaming, that's a given. However, I figured the whole reason they went with the AMD Jaguar chip was because they could turn the cores off when not in use and get much better efficiency versus the Cell. They could not turn off cores with the Cell, which was/is alot of wasted energy. Maybe 80W is the result of cores being shutoff, which would normally be higher. I envisioned efficiency better than its predecessor.
That chart seems off. My 7950 is more quiet than my old 660ti. And that 660ti was louder than my launch ps3.
right so it has little bearing on what youre going to hear in your living room...the PS4 measurements barely went over the ambient sound levels of the room...only by a couple db...thats pretty good...
if those video cards were measure in the same way the PS4 was they would probably give off very similar numbers because you would always be picking up the ambient noise in the room...
Keep in mind these aren't power sipping Intel components, AMD have historically had issues keeping idle consumption down on their CPU components. Even at the lower TDP end.
I imagine even while idle the UI requires GPU input so that'd increase the Idle consumption as well.
A watt is 1 joule per second. Something that uses 1 watt will draw 1 watt-hour over 1 hour. The amount of electricity you use is measured in kilowatt-hours normally, but for the purposes of instantaneous power consumption; we use watts.

thanks.
would you mind jotting down an equation similar to the ones on the chart on this page to better help me/others understand. based on 2 hours of game operation per day as a base line estimated at 140W
At 140W:
0.14kW x 2 hrs/day x 365 days/yr = 102.2 kWh / year
Here in QLD Australia, our electricity is somewhere around 25-30cents / kWh. That equates to something like 30 bux a year.

Exactly what I was thinking.

How do those noise levels compare to PS3/360?
Okay, thanks for the clarification. So if we take into account the ambient noise level of 40 dB, then PS4 noise level while playing games is around 37-38 dB (@ 1 meter). Not too great, but not a complete disaster either. During Blu-ray playback it drops to below 30 dB, which is nice.

Louder than slim versions, quieter than launch versions.

PS4 dBA under full load seems to be comparable to the AMD Radeon 290x in Quiet Mode.

Has the standby mode been measured?
Your city reaches 50 degrees Celsius in summer...?
And is that temp playing a game? I can't read article.

Idle is a great feature and people are mistaking this for standby. It is for downloading patches or games and it shuts off when completed.
Oh Ffs.....
Damn, going above 50 C regularly is like death to me. Are you sure it's not time to move?
This isn't a netbook class CPU. It employs the same architecture as AMD's netbook CPU's but it's got 8 cores instead of the typical 1 or 2 found in a netbook.
Of course there's a discussion, there's a cpu, gpu, 8GB of fast gddr5 and other components fired up.
Jesus what do you armchair expert electronic engineering geniuses expect?
For those saying by the time they pick there's up there'll be a slimmer more efficient model: is that even possible this time?
Seems to me that the PS4 can't really be made any smaller. You've got bits like the HDD and Blu-Ray drive that simply cannot go any smaller, and the motherboard is already concise.
Anyone feel Sony will struggle to get out a better model?

Have you ever actually hooked up your PC to a power meter?

I still think for the first model they should have made the case, heatsink, and fan larger, maybe even an external PSU. More room for overclocking, quieter, less potential for overheating.
I mean how much slimmer can it get? It's already PS3 slim size, right? (not super slim)

No. They've duct taped 2 4-core jaguar blocks (the ones they'll be using for those lower end laptops) together in the APu along with heir respective Gpus

How many transistors does the duct tape take up? (joking)

db is not the same as dbA: http://whatis.techtarget.com/definition/A-weighted-decibels-dBA-or-dBa-or-dBa
So, not comparable.
Well, Sony surprised a lot of people with this model to begin with so I wouldn't be surprised if their engineers can pull off more magic or at least sacrifice some areas to improve the important ones depending on what they're going for.
I wonder if they'll eventually make a cheaper model (when it's mainstream entertainment time of the generation cycle) where it's just a normal box shape too (I don't mean ugly but at least just a normal profile).
No matter what, there's always room for redesigning a console and they seem to love to do it so they can focus on different things or shapes for redesigns. I don't think we'll get the Apple trash-bin design though.

They can make the power supply external, and reduce the size of the motherboard, so yes, a smaller PS4 is possible.
It's almost the same in this case due to the characteristics of fan noise.
Maybe if it was possible to plug in these components to the wall then it'd be kind of true.
Smaller process traditionally means better power profile and this means smaller cooling as well.
Problem?

Wat?
My Core i5 Quad Core idles at 1.6GHz at 31 celsius with an all in one watercooler with 2x 140mm fans in push and pull in a case with 2x 200mm fans and several other 140mm fans.
At load my CPU pushes out 50 celsius and GPU 70 celsius.
PS4 APU (CPU+GPU) in a tiny package at load is at 45 celsius, that's quite a feat.

Joke is on you. Jaguar is AMD competitor for atom - only diffrence is you get more cores here.
Why are you comparing temperatures directly from thermal diodes inside core of cpu to whatever eurogamer is measuring ?
No it's not.
The article says the air is 50 celsius and the case is 45. Core temps would likely be around the 80 mark.

I know its a terrible comparison I just don't get why people are saying it's too hot and uses too much power.
I think the assumption is that because it's a Netbook architecture CPU it should have a TDP of like 15W.
