For a long time network cards were all about performance. Most of you probably started with a 10 Mbit network card, switching to 100 Mbit later on. Modern computers even have 1 Gbit network cards and servers can use 10 Gbit connections. For wireless network cards a similar summary can be created, using the 802.11 b/g/a/n specification.
But nowadays the network device in your computer is about more than just speed. Speed comes at a cost, particularly due to power consumption. And don’t we all want to go green?
Realtek FE/GbE Family Controller Network Drivers
For computers with a Realtek network card, the latest device drivers offer a lot of control on the network speed and power consumption. That way, you can make sure your notebook battery lasts as long as possible.
A few of the settings the latest Realtek network drivers offer:
- Auto Disable Gigabit – this option allows the user to configure if the gigabit option should be auto-disabled on re-link.
- Green Ethernet – this option enables the feature to detect the length of the connected network cable and adjust the voltage accordingly (lower for shorter cables).
- Interrupt Moderation – when enabled the frequency of the CPU interrupts will be lowered when there is less network traffic. Lower CPU usage, lower power!
There are obviously many more settings, not all relevant to network speed and energy consumption. But in all cases, make sure you install the latest Realtek network drivers to benefit from these features.
