XBox 360
Running Dashboard: 135W
Running Media Center Extender (MCX): 134W
MCX Television: 134W
Running Ridge Racer 6 startup video: 152W
Playing Ridge Racer 6: 164W
For Comparison
Pentium D 820 + Radeon X700 (Idle): 125W
Pentium D 820 + Radeon X700 (3D Mark05 Game1): 201W
Athlon 64 X2 3800+ Radeon X700 (Idle): 114W
Athlon 64 X2 3800+ Radeon X700 (3D Mark05 Game): 175W
PS2 (Idle): 30W
PS2 (GT3): 33W

Xbox 360
Dashboard Startup: 38.5 dB
DVD playback: 38.6 dB
Ridge Racer 6 Startup: 54.8 dB
For Comparsion
VAIO Type X Living (Windows Startup): 35.2 dB
VAIO Type X Living (Loading DVD Disc): 37.0 dB
VAIO Type X Videostation (Recording): 42.0 dB
CoCoon CSV-EX9 (Recording): 36.0 dB

According to the article, 40 dB is the threshold at which we become aware of the sound, and above 50 dB it becomes "noisy".
 
Kind of silly that the A64 X2 PCs were running a mere X700 instead of X1800 or something that would be a better power match for Xenos.
 
Seems to be accurate. c't measured the same values of noise and power consumption.
I find it a little bit strange that consoles have now the same power consumption as PCs and are even noiser.

They must be hard or hearing, 40db is already quite noisy.
 
All I know is my 360 is much much louder\hotter than either my PS2, Xbox or my laptop probably all of them combined!

As I've said in another thread, I keep thinking mine's noisy until I turn on the original Xbox that is next to it, the original is actually louder in my case at least

i find these interesting....

9800xt=60 watts under load
1800xl=60 watts under load
7800 gt=~60 watts under load

amdx2 3800=65 watts under load

now if we add-on ~15 watts for a dvd drive,we get ~140 watts under load.

i'm pretty suprised the 360 consumes so much power even if it is more powerful than the
above system.

i assume being a console it was designed to consume as little power as possible?

i wonder what ps3 will be? my guess is ~180 watts under load...:oops:

You might want to have ram in your sample system, but I am probably just nitpicking. ;)

USB also takes power etc.

oops! how much more power would ram require though?

my real point though is why relatively inefficient pc parts consume the same or less power
than parts for a (small) console?

and yeah it is nitpicking;) :devilish:

Well they really aren't .

I believe basic MB functionality costs 20+ watts, memory is around 10 watts per stick add a few watts for a case fan and a powersupply fan, your amd x2 system will be upwards of 180watts.

Err, I dont think so. X1800XT's and 7800GTX's both use upwards of 110watts max, dont they?

I'm surprised the X360 comes in so low. I wish the GPU used more than 35 watts.

From what I found the X700 is around the same as a 9800PRO class card, it's 8 pipes.

I dont see the big loss for the 360..the CPU's are probably about the same but the PC rig is running a much lower class video card, and those are the two items that draw the most power, and they're coming in about the same watt figures. X360 actually slightly lower.

I dont see the PC's RAM amount mentioned.

Interesting stuff, though.

i believe.

I don't think an x700 is using anywhere near 60 watts. An x800xt uses 60 watts under load. I'd be surprised if an x700 were much over 40.

1800xt 512mb=112 watts under load
7800gtx 256=80 watts under load

i forgot about ram!:oops: add ~20 watts

here's the link i got these http://www.xbitlabs.com/articles/video/display/geforce7800gtx512_5.html

the thing that worrys me the most about the 360 figures is the consumption at idle/dashboard and dvd playback.

the difference between idle/playing rr6=30 watts.compare this to the 7800 gtx 512 in the
above link:idle=32 watts under load=95 watts.difference=63 watts.

surely the 360 should have better power managment than a pc part?
or is that wishful thinking these days?

on top of that,the 360 only has a ~200 watt power supply which doesn't seem alot to me.

*all imo and i reserve the right to be completely wrong!*

Your figures seem (sometimes vastly) overstated to me. If a stick of RAM would really draw 10W it would burn up. You'd need a sizeable heatsink to dissipate that amount of power on such a small area passively. Harddrives when idling typically consume less than 10W, and they get pretty warm despite being much bigger than a DIMM. Hot as they ran, early Rambus DRDRAM sticks drew only ~4W maximum.

20W for mobo, no I don't think so. Case fans, well, most silent type fans are about 1W for 80mm, maybe 1.5W for 120mm. Some "ultra silent" type fans have even less power draw. Standard 80mm, 2-2.5W is common.
