There is very little difference between the two controller on end-use. Both, in practice, support the same number of port queues. The old controller actually uses less power even on its larger lithography. The difference lies in a 2.1 compatible pci-e interface vs pci-e 2.0 (unimportant at dual port speeds). The old controller offers IPSec off-loading while the new one does not. The new controller supports green Ethernet, the old one does not not.

The main difference is that VMWare, Citrix, Microsoft, etc. will be supporting the new controller. For instance, the old 82576EB controller (used by the E1G42ET) is not supported on Windows Server 2012 R2. VMWare also has questionable intentions of supporting the controller on their next release. SO keep that in mind. If they're price price competitive, you might as well stick with the new controller. I personally do not have any issues using teaming on my i350 NICs.

In addition many of us are Not yet adjusted to the fact that prices are Not anymore established by engineers and production managers.

Prices these days are established and controlled by marketing people, technology variances in them is very low as a cost factor.

As an example on the opposite side) a Laptop with 240GB SSD usualy cost hunderds of $$ more than the same with 60GB SSD. The real diffrence in price between them is about $50.

I'm buying a dual port NIC and the I350-T2 seems to be Intel's latest. However, I'm a little confused as to why the older E1G42ET NIC is still for sale alongside it, and even costs more. What advantage does the ET have over the I350 if any?

There's even been a I340 between them, which has come and gone, yet the ET is still sold.

I'm also concerned about complaints I've read that the I350 seems to have issues with teaming, which makes me lean towards the E1G42ET.

The older NICs are supported by everything, while the newer NICs might not have driver support out of the box for all the software you might want to run. So part of this is just a matter of convenience.

I have heard it said that the engineering teams for some of the newer chips are not the same as the folks who engineered the old chips and are not as good, and the newer chips are believed to be buggier. Take with appropriate dose of salt.

That is true the team got paid $$$ and joined Realtek

I hope not, realtek network stuff has always been bottom of the barrel in terms of performance and driver support. This is especially true when it gets into wireless gear

Not the bottom of the barrel, just somewhere in the lower stratum. There stuff does tend to work better than the old Atheros stuff. At least in terms of Wifi, since Qualcomm has taken over, that isn't true. On the wired side of things, at least the newest atheros NIC I've seen was horrible garbage. My experience with Realtek NICs isn't terribly extensive, but they've always worked okay for me. My Realtek USB3 GbE adapter works better than the couple of ASIX based ones I've used in the past.

Nothing compared to Intel, or maybe even compared to Broadcom/Marvel though.

We will just have disagree then, especially when it comes to wireless. Their wireless devices are just plain awful.

 

[azazel1024]

Oh no, their wireless is total cold dog feces. Just in my experience their wired stuff is the best of the bottom of the barrel, which again, doesn't necessarly say overly wonderful things, I but I have seen and used many a worse wired card than most Realtek cards.
