PS4 power draw - 80W idle, 120W-140W gaming, max 45 Degrees Celsius exhaust
- Thread starter tipoo
- Start date
Speaking of "clock speeds".....do we know what the official clock speed of the PS4's CPU is yet?

Why is it bad?
What were you expecting? A randomised control trial with 5000 units for a decent sample size?
Also concur with the post above. Does anyone know?
Seems like that isn't so obvious if you scroll up...
From an AMD solution? It could have been much worse.
The outside of a PC's case ought to be cooler than that.
I was expecting them to choose some other place than the goddamn Piccadilly Circus for their noise measurements. Then they proudly report them rounded to the nearest decibel.
Assuming they were rounded, a low estimate would be 41.6 dB - 40.4 dB = 35.4 dB, and a high estimate would be 42.4 dB - 39.6 dB = 39.2 dB.
45C is the exhaust temp, not the core temp. The core temp will be quite a bit higher.
Oh wow...I didn't realize their ambient noise level was 40dB. That's a bit ridiculous.
Since Sony is quiet, it is safe to assume is lower than Xbone's. To be honest, they didn't talk about True Audio even when MS was playing the SHAPE card. The point is that Sony is now in a position where, even if they tout unquestionable advantages, they will likely draw unnecessary fire from the press. It is very smart of them to just shut up, really.
Sorry for going OT.
This is just not true.
Acer still puts out some great 11.6 inch LED netbooks.
The Acer Aspire One AO756 series that launched in 2012 comes with a dual-core Celeron 877 or (or Pentium). The Celeron versions are actually a bit faster than the Pentium models. Yet both are "real" laptop-class CPUs (that is, laptop CPUs from several years ago) in comparison to netbooks that use Intel Atom CPUs or AMD Bobcat-based APUs.
I own the Acer Aspire One AO756-2808 that came with 4 GB DDR3 RAM and a 500 GB HDD. I also just got a hardly-ever used AO756-2623 that was for sale on Amazon-- I believe this unit may have started with 2 GB RAM though it was 4 GB when I ordered it. I had the seller upgrade to 8 GB RAM. because it had a smaller 320 GB HDD.
The Celeron 877 units that I have are lightning fast with either 4 or 8 GB RAM. It's easy to upgrade the RAM unlike older Aspire One netbooks, and it seems relatively easy (from the videos I've seen) to upgrade to a solid-state drive/SSD. You just have to check to make sure you get an SSD with the right dimensions.
One can even upgrade to 1333 MHz DDR3 provided both RAM sticks are the same speed. I haven't tried this yet.
I've had 2 older netbooks in the past, both had Intel Atom. One had 1 GB and the other had 2 GB. I'd say the Acer AO756 series is world ahead of old Netbooks with Atom and still significantly faster than newer netbooks with an AMD APU.

p.s. While she is right about the speakers not being good, you CAN adjust the sound/speaker settings to improve it, somewhat. However I just use HDMI output to my 1080p LED and switch to 1920 x 1080, 60p Hz in the Intel HD graphics settings. In fact, I'm using the 8 GB Netbook right now.

Why? A 7850 only draws 80-90W on average when playing games.

It was pretty clear to me from the start that this was it. I mean it's struggling to keep 1080p 30 fps at launch, most launch title don't even use AA or AF (I mean come on, AF eat like 2-3 FPS..). XBOX game where 720p at start, then they started added effects, and they lowered the resolution as time gone. Pretty sure 900p and lower will be the standard in 2 years..

Before posting something like this you should check your facts, the HD7850 use less than 100w on full load.

Shows 110W
http://www.anandtech.com/show/5625/...-7850-review-rounding-out-southern-islands/17
Math required (106W - 189W)
The mobile version (7970M) uses less than 100W though
I wasn't expecting an announcement from Sony but.... I thought with the some of the PS4's already out there some of the experts would have dissected by now and throw out a number for us.

Max power draw below launch PS3? Dat wizardry.
I think you need to look at the 7850 again...

That is not very good, considering the entire focus of the computing industry the past several years has been on power consumption and, subsequently, noise/heat.
My guess is that the PS4 OS is not optimized for standby and low power states at all.

Amazing, Sony is getting more power per wattage than the Wii U. Nintendo really got screwed with their hardware.
Impressive hardware Sony.
Impressive hardware Sony.
It is optimized very well for standby, rumors are that the power consumption is between 0.5-2W during standby.
Idle on the Menu is completely different to standby.

Idle seems a bit high, but just for reference a 7850 runs at 130w max TDP
Very nice explanation, thanks.
FWIW Ars has slightly different power draw numbers

28nm vs 45 and 40, is that surprising? Anyone expecting magical efficiency out of the Wii U was setting themselves up for letdown.

Wow those heat numbers with an internal PSU? WOW.
I expected atleast PC GPU numbers of around 60c during gameplay bouts.
But @ 80w if you ran the PS4 idle for 24 hours a day all year long, you would pay 92$ a year if you had .13c per kw/h

Standard office noise is above 40, so doesn't suprise me if they weren't using a specialized lab.
Idle =/= standby, in case you confused them. Standby will still consume almost no power. Idle is sitting while on without a game in.
And yeah, the exhaust goes over the PSU too which explains some of the warmness.

My guess also.
Started a thread on this at Semiaccurate. There are a couple of modes where the GPU should be turned off which would drop power consumption by 40-60 watts.

BUT when OS UI overlay is enabled the power goes up by about 20 watts and stays there even if there is no update to the UI. This has to mean some hardware is turned on, either a power gated GPU block or a second GPU outside the APU.
I noticed the power went up when a UI Overlay is called from within a game with my own measurements but mine showed more than 10 watts but less than 20 watts increase.
Nonsense.

Either one would be a surprise wouldn't it. If AMD is to have larger GPUs in their APUs they need a smaller GPU block with a UI overlay for Browser and XTV and a larger GPU for Games and compute. Right now they do this with small GPU in APU and larger dGPU as AMD GPUs do not individually power gate the CUs, they are all on or off. In contrast ARM GPUs are individually gated and multiple GPUs are designed to work together. UI/webgl makes a good point to seperate functionality.
its 10, not 80.

The only people who did are fools who don't know anything about technology. Its fantastic as it was a good barometer to see who knew anything about technology and who didn't (guess what, the bad games industry folk argued that GDDR5 would be HOT HOT HOT).
One second of thought would tell you "yes it consumers more energy and puts out more heat, not enough to matter". GPUs generally don't have hugeass heatsinks on their GDDR5 modules and a lot of cards have people overclocking memory by 1000mhz and more.

it is actually 10w... 80w is when console is still doing stuff in the background despite looking like it is in standby. Confirmed by Ars on 2nd try.
That makes a lot more sense.

Yeah that sounds about right.
standby and idle arent the same thing. it's ~10w in standby and around 70 idle
Standby is 10. Idle is 80.

Ahhh... okay. evnthough 10W is a bit much these days, but acceptable.
I don't remember reading this. They first had standby at 70w (which is ridiculous) and then corrected to 10w. Not idle.
