Power usage

Post by alpha_one_x86 »

Hello, I have 2x Fit PC 1, why not 2, at the outlet: 4,8W at idle and 5.8W at full.
I look the fit pc 2. My question is: waht is the power consumption at the outlet without wifi and without hdd (sdd or nothing)?

This depends on other factors, but 5-7W is a reasonable assumption.

This number is with witch model of fit pc 2? It's measured or read in a doc?

Hello, is the power consumption and heat dissipation of the Fit-PC2(i) models with 2GHz Z550 processor and 2GB RAM higher than the power consumption of the 1.6GHz Z530 1GB RAM models? Thanks.

The Z550 has slightly higher TDP(max) and powering 2GB RAM will -- in case the same type of ram is used -- add to the overall consumption, too. However, this shouldn't be a dramatic increase.

In practice power consumption of fit-PC2 2GHz/2GB is identical to that of 1.6GHz. This is thanks to the efficient power management in the CPU - under the same processing load the 2GHz CPU idles more.

With fit pc1 (geode 500MHz) I use 10MB of ram, and 0.02% of the cpu.
My target it's minimize this power usage is this case.
Thanks to speed step, all atom have down speed at the idle, seam be 200MHz (and save voltage) to all atom. Then only feature of processor and platforme change the power usage.
