Some people are saying that they don't feel the need for > 1 Gbps in a home network. As a counter-point, I'm regularly limited by 1 Gbps PHY limits. During the 2 years of the pandemic I've been working from home with gigabit Internet. Why gigabit? Because that's the "speed limit" of the Ethernet PHY in the fibre broadband box, and also my laptop's ethernet port. My laptop can write to disk at multiple GB per second,…

It depends on context, but we solved this at work with virtual desktops through VPN. The heavy lifting is done on-site, the users have a thin client that barely exceeds one Mbps.

Yes, virtual desktops suck in several aspects, but we couldn't expect everyone to have gigabit Internet at home.

Yes, but embedded devices and laptops generally don’t have pci-e.

Lots of consumer motherboards don't have a lot of PCIe slots wider than x1 (which is not enough for 10GigE), but they often have multiple NVMe capable M.2 slots, that this card would work with. In my home server for instance, which is built on a consumer μATX board, the wider PCIe slots are filled with a GPU and HBA, which leaves no way to add 10GigE without spending a lot of money on a new motherboard and CPU - or f…

For a home server you probably don't need PCIe 16x for the GPU? If you even need a GPU at all?

Gamers aren't a strong answer :D but they're the audiophiles of home computing hardware and networks and the most likely to overspend in the belief that it's better :D

Hm, that's taking it a bit far given that I've yet to see any gamer who believes that e.g. taping plastic bags with gravel to their network cables [1] will lower their ping times (if it is not for weighing down a cruddy connector which only works when you press the damn thing down, that is).

I love how much more ridiculous this has gotten since I last looked at this space ~15 years ago.

It's interesting to see just how slow faster ethernet standards have been. Feels like I've had gigabit ethernet at a pretty low cost for nearly 20 years now, but faster than that has been pretty esoteric outside of the datacentre. I guess there really isn't much demand for faster than gigabit speeds even now (outside of servers?)

Yep, though it isn't a problem I have any longer, using primarily wifi.

Flash drive writing speeds are my biggest bottleneck, wish someone would tackle that at a reasonable cost.

Another factor: data centres moved to fiber. And fiber is less physically robust and not great for desktop connections or plugging in to a laptop. 10GBASE-T exists, but it turns out pushing 10gbit/s over 100m of twisted pair requires chips that are hot and power hungry. Again, not great for desktops or laptops. And because it’s not used in data centres, there are no economies of scale or trickle down effects. Gigabit…

> fiber is less physically robust Maybe this used to be the case long ago, but I don’t think it’s true today. Personally I’m pretty rough with fiber (having slammed cabinet doors on fiber, looped fiber around posts with a low bend radius, left the ends exposed to dust, etc) and had no issues within a data center. Can’t say the same for copper. Even the cheapest 10km optics have more margin when your link is only 50m.…

Yes, even in my days with FDDI (pre-2000) you could wrap them around your finger, no matter if multi- or single mode. At least for 'demo'-purposes, to stop the hyperventilation of some people. Nonetheless I've seen horrible installations, where I've straightened out the gordic knots when I've seen them, just to be sure ;-)

It's not abysmal when you consider the standard (signaling, ECC) has to work over 80+km range in some cases. You'd be hard pressed to get a pci link to work over 10M.

That being said, I generally agree that it has been moving too slow in consumer electronics and 2.5G is a pretty long overdue step-up for a moore-adjacent technology. Another factor is the humble reality that infrastructure (physical cables installed in walls) is the (s)lowest common denominator in this advancement.

Lots of reasons: 1. Consumer broadband speeds rarely exceed 1Gbps 2. 1Gbps Local network transfers are seldom slowed by the network (as large file work typically involves HDD still) 3. Where local network transfers are impeded by the network speed the transferring itself isn't a frequent enough and blocking thing that people feel they need to fix it... they just go make a cup of tea once or twice a day 4. There are a…

i buy armored multimode patch cables for, i dunno, 10 or 20% more per unit length, and they seem indestructible in my residential short-distance use cases.

> Gigabit Ethernet and wifi being “good enough”

i think this explains it all. when the average user prefers wireless to wired gigabit, we know how much bandwidth they actually need, and it isn't >=gigabit.

As a counterpoint: I had 10G networking and went back to 1G last time I reorganized. Haven’t really missed the 10G for now . I ditched the 10G because the 10G switch was hot and noisy and had a fan, whereas my 1G equipment was silent and low power. This could be overcome by putting the switch in another room, obviously, but I haven’t missed it enough to go through the trouble yet. > During the 2 years of the pandemic…

I am on FIOS 1G home fiber, how does one get 10G ? Do they have run a line from the node or street ?

I rent an apartment in a building that was erected around 2015. They laid an ethernet connection... with a 100Mbps bandwidth limit. Some people just don't care.

Are the ports in pairs at each location? Then it sounds like they did a Very Bad Thing and ran one cable per pair of ports; 100Mbps uses two pairs, so why use two cables when one cable has four pairs, right? :( I've seen that a lot in much older installations, but I'd expect better from 2015 construction. I'm busy retrofitting Ethernet in my house by pulling cat6 through the walls and pulling out the old cat3 phone c…

> Are the ports in pairs at each location?

there are a variety of ways to screw that up. i've seen a house that has a bunch of cat 5e run, but the installer stapled it down, and most of the cables have a staple through them somewhere along the run, killing a pair or two.

Oh. Really?

Why not compare the insane prices of thermal paste and compounds per volume/weight with the stuff that is used industrially?

Not always, but often used for results which could be called statistic noise. Very diminishing returns.

All for pushing reviews with many bar graphs over two dozen pages, and so much more page impressions. Like the rest of gamermedia, too.

Woo!
