Comment on Realtek's $10 tiny 10GbE network adapter is coming to motherboards later this year

Is more than 1Gbps needed for that? That seems insane, but I’m old and watch stuff in full HD so what do I know.

Low latency means low compression. Low compression means high bandwidth.
1080p60 NDI will be 200mbps. If you are doing 2160p60, that’s 800mbps (which is about the limit I would run 1gbe at). Doesn’t leave much overhead for anything else, and a burst of other traffic might cause packet drops or packet rejection due to exceeding the TTL.
2.5gbps would be enough.
But I see 2.5gbps and 5gbps as “stop-gaps”. Data centers standardised on 10/40gbps for a while (before 25/100 and 100/400) - it’s still really common tbh - so the 10gbps tech is cheap.
I don’t see the point in investing in 2.5/5gbps

Yep, and then add multiple streams at that rate… Although it also depends on how your network is setup for how much that will matter. With the right arrangement of switches/cables you might manage it if you always stream between the same devices by just making sure that connection doesn’t share an ethernet cable. But easier to go 10Gbps and not have to worry about it.
Although so far I only do 1 stream and its over wifi. Its fine but obviously ethernet would be better. Mainly use it for sticking a few games on the TV, keep talking and nobody explodes and jackbox games.

Thanks for the info, didn’t think the limit was so close.
My box has 2.5Gbps but I’m with you on that one regardless of my real needs, I’ll wait it out til 10Gbps. If even my geek needs flare up I mean :-)

Most (all?) 10gbe copper switches will negotiate 1/2.5/5 gbps.
Most 10g switches with sfp+ will as well, but you also have to make sure the sfp+ ethernet module will negotiate lower speeds.
I’ve had some annoying interactions between 1gbps and 10gbps when using different sfp+ switches and sfp+ ethernet modules. I never dug into it, I just swapped stuff around until it worked.
So no reason not to get a 10g switch to start building things out
