High CPU usage when High NIC Usage

[Elior Zeno]

Hey,

I use Z170XP-SLI mobo with i7 7700k
The onboard NIC is Intel® GbE LAN chip (10/100/1000 Mbit)
I have 1Gb ISP
When I download at high speeds 600-700Mb/sec+ I noticed the CPU is @ 80-100%
(verified that the download is the main CPU usage)

Is it normal ?
Is this onboard is that crappy ?
Is Intel Gigabit CT Desktop will help ?

Thank !
Elior

Use Windows Task Manager to determine what process(es) are consuming the CPU. In my case it's usually Chrome.

go to your NIC settings and start enabling offload and other CPU reducing features.
