| >Yes and yes (if you meant 200W CPU...)
this is only when the CPU is full loaded.but normaly when use a computer, most time the system is on idle but when do some actions it should go fast.and when ypour computer is faster, it can earlier go sleep.
I dont know what powerusage a PPC970 dual core have when it is on idle, but even on X86 a CPU with TDP of 130 Watt(most X86 have 65 or 95 Watt TDP), the CPU does on idle not need more than 10 Watt.
http://www.tomshardware.com/reviews/intel-cpu-power-consumption,1750-9.html
See here, this diagramm.this are power values of a full system.To see what the CPU need on idle you can calc.
The system with core2 extreme need 94 Watt on idle and 195 Watt when CPU run full. 195-94 mean 101 Watt more.the core 2 extreme is a 130 Watt TDP CPU.
http://de.wikipedia.org/wiki/Liste_der_Intel-Core-Prozessoren#Vierkernprozessoren
much more TDP as a PPC970 need.
but when do nothing this CPU need only 29 Watt.even less.Because its known that Intel use not the full TDP
So the powerstation need on normal use much less power as 200 Watt i think and also a Playstation3 need on idle lots more power i think.
see here about game console power.i find only german page, but see diagram end of page
http://www.computerbase.de/artikel/multimedia/2007/test_sony_playstation_3/24/
they use much more power. So run a OS on a playstation, thats something you can call is a powerwaste. Last edited by bernd_afa on 05-Apr-2010 at 07:40 AM. Last edited by bernd_afa on 05-Apr-2010 at 07:38 AM.

| @bernd_afa The PPC cpu being suggested has *much* better (more fine grained) power management than current Intel CPUs (AFAIK), so it should be able to be "partially active" (not just idle) while using less power than Intel.
It is quite easy to have low power usage when doing nothing. It is rather harder to have low power usage when parts of the CPU are being used occasionally. As I recall, Intel's CPU power management is also quite crude (only powering down after a long time of inactivity), so it wouldn't take much to keep parts of the Intel CPU powered.
However, this is just my vague recollection. Last edited by ChrisH on 05-Apr-2010 at 11:52 AM.

Here is a table for PPC970.the low voltage PPC 970 seem reach only 1,25 GHZ.so this the powerstation have not.
http://www.ppcnux.de/?q=node/6110
when use D.Nap and F/64 then it need 17 Watt for 2 Cores.the power station have 2*2 core CPU so need 34 Watt on idle.
But here stand the 2. core can complete switch off,then need 18 Watt |

Thus they need 34 Watt when doing "nothing"... two PA6T cores need only 15W (2 GHz) with full workload... (cca 2.5 W in Doze and 2 W in Nap mode - for whole chip) |

| To me this: "To date all A1-X1000 motherboards have used CPU Samples and to avoid potential damage we have not run the CPU to its maximum rating. However watch this space??? " tells that the SoC might not be PA6T after all. I think after 3 years of production, no one should use PA6T CPU/SoC samples any more.
So... Is there a new production run and/or new revision of PA6T coming out soon or is this something else... _________________ - KimmoK // For freedom, for honor, for AMIGA // // Thing that I should find more time for: CC64 - 64bit Community Computer?
