Is Kentsfield really a power hunger monster?!let's see the power consumption comparison between quad-core kentsfield and dual core core2 extreme!
platform
M/B ：ASUS P5B Deluxe
MEM ：TREEM DDRII 800 2GB Dual Channel
HDD ：Seagate 250g SATAII 16Mb Cache
VGA CARD ：MSI 7950GT
POWER: ACBel iPLUS 550W
OS ：WIN SEVER 2003
CPU COOLER：Tower 120
CPU ：Intel Core 2 Duo Conroe E6600 4mb cache
CPU ：Intel Core 2 Duo Kentsfield QX6600 8mb cache
when dual core Vcore=1.35v,3.6G idle
From monitor reading,power consumption is 89W(stable)
dual core 3.6G running Dual SP2004
the highest power consumption reading is 176W(150W~165W up and down)
Now let's see quad-cores
kensfield Vcore=1.50v,3.6G idle
From monitorreadings,power consumption is 103W(stable),it's more than dual core around 14W
Quad cores3.6Grunning the Dual SP2004,
The highest moment for power consumption is 257W(225W~241W jumping,even though it's only running 2 cores at the same time
; but it is still more than the dual core's 176W about 81W
now, I let the quad core running Quad SP2004
the highest moment for power consumption increased to 298W,(most of the time for jumping around )
Conclusion:At the same freq of 3.6GHZ
Quad core cpu power consumption is 1.16 times off dual core
for the highest moment of power consumption then will be the 1.69 times off dual core.
