I210-T1 / I350-T2 power consumption?

Hi,

i want to know the power consumption of the I210-T1 and I350-T2 adapters cause I'm not sure

if it's right what the datasheed says.

Intel writes 0.81 Watt for the "Intel Ethernet Server Adapter I210-T1" but the "Intel Ethernet Server Adapter I350-T2" needs 4.40 Watt?

And then there is from HP the "E0X95AA Intel Ethernet I210-T1 GbE" where HP writes 3.00 Watt.

I believe the Intel and HP cards are nearly the same, so why that big difference.

Also i can use 5 "Intel Ethernet Server Adapter I210-T1" and still have lower power consumption then with 1 I350-T2?
