Stupid question about network cards

Question

Computer networks

Good afternoon,

there are 2 network cards: one built-in Intel 82567LF Gigabit Ethernet Controller and the second Intel PRO / 100 S Desktop Adapter.

The question is which is better to use in terms of CPU usage? (From the computer on which it is installed, something is constantly downloaded via the internal network, movies are watched + the torrent works.)

Now I use Intel PRO / 100 S, I would just like to know whether it is worth occupying a slot or is it easier to use the built-in network card?

and the same question, if let's say the built-in network card is not Intel, but let's say Realtek 8111D.

Answer 1

In terms of processor, all network cards are the same.

Answer 2

take into account that the built-in one is gigabit, and the external one is just a hundredth.

Answer 3

82567LF
It is also “empty”, although it may support offloading ...

Answer 4

I would suggest that in your case the problem is not at all in the network card, but in constant reading / writing to the screw. In 99% of cases, the network card almost does not load the processor. If you have a gigabit home network, then it's a sin not to use the built-in gigabit card. If you have 100 Mbps and you want to save the processor (at home all your housemates download from you and you want to play Skyrim on this computer), then take the Intel PRO / 100 S. If you don’t care about 3-5% of the processor load, take built-in. When choosing between Intel and Realtek, I would choose the latter. I have a bad attitude towards Intel because of the drivers in the segment of cheap network cards.

Answer 5

I'm afraid that in the case of an ordinary 100 megabit stream, you will not be threatened with at least some kind of optimization due to a network card. You can safely use the built-in one, since it is newer and clearly has more hardware features with the same checksum calculations.

Answer 6

In your case, when using the built-in network card, the load will increase only if your internal network is gigabit and there will be a larger stream from your machine as a result.

Answer 7

Use built-in, all the same the difference is imperceptible. And if the channel is loaded, it is necessary to shape them) So comrade kreativf answered like he noticed the difference, see the screw.

Answer 8

>From the computer on which this is installed, something is constantly downloaded over the internal network.
Solely because of the negative experience of connecting to all sorts of homenets / leftnets, I personally would still use Intel, not an integrated card.
Everything happened: lightning, and water leaking through the inside of the cable, and connecting from the other side to telephone / electrical networks.
Sometimes network cards died, so it's better to change an inexpensive "external board" than to get a defective motherboard.
