HP MediaSmart Processor

Funny, last night I was messing with my HP MediaSmart server and my Watt Meter.

I was trying to figure out what kind of processor the MediaSmart has. You may not know but there are 2 different AMD Sempron 3400+ Manila processors.

Model Number Voltage TDP Part Number
Sempron 3400+ 1.25-1.40 V 62 W

SDA3400IAA3CN
SDA3400IAA3CW

Sempron 3400+ 1.20/1.25 V 35 W SDD3400IAA3CN

Scott Hanselman confirmed my results. I see around 57W usage on my server with a peak of 73W at 100% CPU. I also have two 500GB drives in mine.

There is a big difference between a processor maxing at 62W and 35W. However, I think that the HP MediaSmart has the 62W processor.

update: According to this interview, the MediaSmart does in fact use the 35W Sempron.

Question: Does the HP MediaSmart Server have a power save mode or sleep type mode when I'm not using it? Is it quieter than a standard computer?

Answer: The MediaSmart Server was designed to be as quiet and power efficient as possible. Example: The processor we chose was a special 35W processor. This low power design helps keep noise levels down too. Since the server can be accessed by any network device at any time (locally or remotely) there is no "stand-by" mode.

So, given that the CPU is rated at 35W Peak, and I got my machine up to about 73W peak, that means that power consumption is about:

Component Power
CPU 35W
Drive 1 ~7W
Drive 2 ~7W
Misc (LED, NIC, chipsets) ~6W
Loss due to PSU (75% efficient) 18W
