Peak Power: 180 Watts
I did a few power consumption tests on my old system just to see how well the new Intel Core 2 Duo E6600 I have now competes in this area. And I have to say it competes better than expected!
I have done the same encoding test again on my new system and despite that it is more than 10 times faster the peak power consumption during conversion was only 163 Watts this time considering the extreme performance boost this is even more impressive! Although I have no comparison I think the E6600 is literally really on the level of an AMD FX-62 but with a way lower power consumption
My new system config:
Intel Core 2 Duo E6600
Asus P5B Deluxe Wifi/AP (probably consumes more power than my old Asus A8N-SLI Premium)
2x 1 GB Corsair XMS2 PC2-800 CL5 Memory @1.9V (Standard)
3x 320 GB Seagate Barracuda 7200.10 (PPR drives)
The rest of my system config is the same as in the other thread above. So my new system requires 17 Watts less power than my old system in this specific test although I have a more demanding motherboard, twice as much memory and 3 instead of 2 hard drives. So the CPU probably saves even more than those 17 Watts which would be normal since it has a 65 W TDP rating vs. a 89 W TDP rating of the X2 3800+ I had before.
On a site note, the Barracuda 7200.10 drives are extremely fast and extremely silent compared to my Maxtor DiamondMax 10 I had before, so I would definitely recommend them as well for a silent system! Also temp-wise they only have 33-36 °C in my system cooled with a Scythe Ninja cooler @5V originally shipped with the Scythe Ninja heatsink I use to cool the CPU but I equipped that one with a SX1.
