Intel Gigabit LAN vs Realtek

post #1 of 13
Thread Starter 
Quick question fellas...

What are the benefits, if there are any, of motherboards with Intel Gigabit LAN instead of the standard Realtek one?
post #2 of 13
I personally don't think there is a difference. IMO, i do believe i feel a difference when using a pci network adapter vs onboard. Seems like my file transfers are snappier.

Hope that helps.

Lower CPU utilization and better throughput.

You won't notice the difference unless you do lots of local transfers on a gigabit network though.

Mostly quality (you know it won't fail in a matter of months and the drivers are stable) and maybe features/settings.

I'd go as far to say you wouldn't see any performance difference at all. These newer cards all do checksum offloading on their own and don't require much cpu IRQ cycles

The only real problem I've experienced between the two have to do specifically how programs interact with their drivers. Wireshark has a tendency not to display VLAN tags in frames with Realtec, which isn't huge but requires some annoyances to get working. For all day - every day tasks I don't see anything to be concerned about. Pick whichever one you like best..

Thanks for all the help you guys.

So I guess I won't see any difference while gaming with a standard Realtek one vs a Intel one.

They are all based on the same IEEE 802.3 standards. Each have their own quarks but nothing to even bother thinking about, let alone worry about.

^ What he said.

I think you will mainly notice the difference when you start doing more advanced things, like Teaming, Jumbo Frames, etc.
Gaming is pretty light on the network card anyhow.

Motherboards with dual Realteks, IIRC, support etherchannel (uses both in tandem.) You would need a switch that supports this feature though.

That's not true.... since PCI network adapters often are the same chip (Atheros, Realtek, Broadcom, etc) as the ones used onboard.

Based on standard is different from hardware implementation... Sandy Bridge and K10.5 both support the x86-64 instruction set but that does not mean they are both capable of the same performance.

Here's some benchmarks: http://www.linux.com/archive/feature/131340

For many users, it won't matter.... but if you start providing heavier loads (achieving a constant 110MB/s for a transfer, installs over network) or more advanced tasks (PXE, VMs), then a dedicated network card may improve performance.
