Is there a difference in reliably and performance with onboard Gigabit Ethernet LAN made by Realtek, Marvell, Intel? Is one better than the other?

More about : realtek marvell intel

For what purpose?
If this is for a home computer, then no.

Really depends on the chip, as there are many different chips made from each company
but as long as they have (or there are) bugless drivers for their chips, I'm content
as for current onboard ethernet, they should all be the same unless you are utilizing your computer with some super fast connection or are using it as a dedicated server - then I wouldn't use onboard
if I did have to choose one, my preference would be Intel as I had great experience with their NICs

I always think separate NICs are better (as in performance) than their onboard counterparts (I could be wrong though)
my old mobo doesn't have onboard lan and I would disable it if it did

Onboard is the same as the card its self - they use the same pci/pcie bus etc.

Intel has the advantage of equal or better throughput aswell as lower cpu usage

Well...it really comes down to this: a LAN chipset is only as good as the interface that it is connected to. A PCI NIC will have roughly the same performance as a onboard chipset connected through the PCI bus, and a PCIe NIC will have roughly the same performance as a onboard chipset connected through the PCIe bus, but a PCIe of either will KILL a PCI of either, even if the bus is only of x1 width.

Now, moving on to your question of brands...I've never seen an Intel onboard chipset, so I really can't address that, but, both Marvell and Realtek make good stuff, so you're fine with either. Just remember, PCIe > PCI.

Onboard Realtek tend to transfer at around 30MB/sec on Vista, Onboard Marvell around 35MB/sec.. while my PCIe x1 Intel transfers around 55MB/sec.

There is a difference. The Intel NIC is a hardware solution with a dedicated Network processor whereas the Realtek and Marvell solutions are simply a Codec (think of it as AC97) with the processing being handled by the system processor.

Intel NIC's also have a lower ping in games.

I believe it needs to be evaluated on a chip by chip basis. The last comment on this thread was 2008, it's 2013, but for example Marvell's 88E8059 chip (now a few years old) states in it's product PDF:

Feature:
• Host offloads - TCP/IP and UDP Checksum offload - TCP segmentation offload/large-send support - Interrupt moderation
Benefit:
• Providing offloading from the host system CPU and Input and Output (I/O) resources to improve application response • Lower CPU utilization

This would suggest this specific chip is not simply a Codec.
