power consumption of my x3360 (kill-a-watt)
Posted: Sat May 17, 2008 5:53 am
Got bored yesterday, so I ran checked out the power consumption of my X3360 system for shits and giggles with my kill-a-watt.
Powered Hardware Details:
That's it... no other hardware (speakers, monitor, etc.) was in the loop.
Kill-a-Watt Readings
Idle in BIOS screens - 158 W
Idle in BIOS screens with both HDD's unplugged - 144 W
Idle (with speedstep active in XP x64) - 137 W
Load (prime95 v25.6 small FFT) - 213 W
Load (prime95 v25.6 large FFT) - 216 W
Load (prime95 v25.6 blend) - 210 W
Playing Crysis - 237-241 W
x264 encode - 197 W
Standby - 0 W
No real point to this post beyond just trivial information! It is interesting to me that the large FFTs consistently read 3-4 watts higher than the small ones did which is inline with the software's description of the large FFTs as generating the max heat/power consumption. Here is the similar analysis of my older Q6600-based system, but there are too many changes (MB, settings, video board, memory, etc.) for a "which processor is more power efficient" comparison.
What is little bit crazy is that both systems draw the same while idle, and even @ 3.4 GHz, and faster memory, the X3360-based system uses less wattage on p95.
