That did not answer my question. I am asking about Ethernet switches vs. SFP+ switches in general.
Does a 10gbe switch use more power as you plug more things into it? Does it stay cool when idle?
Or does it always use the same amount of power while making the same amount of heat even if there is no load on it? _________________ For people who are new to the dd-wrt forums >> http://www.catb.org/~esr/faqs/smart-questions.html#rtfm

Why hasnt Cat6 become more common in the home? Are there not enough people interested in having an awesome LAN network AT LEAST for the sheer giggles of it?
10G-BaseT ethernet has remained stubbornly expensive (on many fronts) and little progress has been made in the last decade towards making it consumer friendly. I've been watching with interest and hope.
Basically, it takes a lot of electrical and computational power to jam 10gbit down a copper ethernet cable.
Direct-attach SFP (also copper cable) is barely noticeable milliwatts. Optical 10g runs 0.4-0.7w. Top-notch modern 10g cards need 3.5w minimum and more if the cable is longer.
In the enterprise, 10GbT has not had a lot of acceptance. 10g twisted pair copper cabling is very thick, very expensive, prone to crosstalk over length and a dead-end speed-wise.
A pair of 2mm jacket fibres suffers none of those problems, takes up much less space and currently can support anything from 10mbit to 50gbit at lengths copper can only dream of. Fibre is cheaper than copper on every metric.
Aquantia got all exciting there in 2017/18 with disrupting the industry with smaller, lower power and cheaper 10g, but their products are pretty poor and since being acquired by Marvell, have pretty much been killed off.

NVME drives on the other hand are capable of doing 3,500MBps. thats around 28gbps.
Modern PCIe4 units can do nearly double that. 50gbit network needed.

and honestly don't know where the problem is with 1gbit LAN
1Gbit LAN allows transfer rates of ~111MegaBytes/second
that is 60GB in 10Min
Faster to sneakernet it with USB/TB NVMe drives.
Hell, even modern high-capacity spinning rust can exceed 1gbit by a long way.

Or most of one UHD BluRay. Sucks when you want to move a few of those around.

i doubt that the average consumer cares
That is entirely true. Certainly they do not care enough to throw the extra money required for 10G

Yes, every active port increases the power draw & heat production on all kinds of switches.
SFP+ & fibre 10g is crazy cheap now. Enterprise is dumping all their 10g gear because it's too slow and not readily compatible with 25/50/100g gear - and they only have so much physical space in the pipes, cable trays and holes in the walls to feed data through. Why waste 4mm^2 on doing 10g when you can jam 5x that bandwidth in the same space?
Plus why waste 10 watts on a measly 10gbit when that same 10 watts can run a 200/400g optical module?
10g optical modules and fibres are so cheap, they're cheaper than copper at any great length. It's nuts.
