Go back to /v/

What SBCs use A53 cores other than the raspberry pi 3?

>>857752

Well, if you can use computing power and generate heat in an efficient way, it doesn't sound too bad.

welcome to the middle ages.

>If not how long before we can browse the Internet for power consumption under 25W outside low spec mobile hardware?

Why not low spec hardware? Why would you need performance?

And about web browsing, it's not possible to do it (comfortably) even on $2000 PC.

>>857797

Not sure if you are baiting with the last sentence, but by low spec I mean anemic hardware.

1.3 GHz dual cores with 512MB to 1GB of ram sort of thing.

>>857800

Since low wattage system with 4GB of ram and paired with a good ARM chip would be perfect for me at least.

>>857800

It is true, if some pajeetscript that is single-threaded by design is running in expinential time brute force will do preciously little. Modern web is shit everywhere. Low power works fine for most tasks if the software is well written.

>If not how long before we can browse the Internet for power consumption under 25W outside low spec mobile hardware?

A couple of years ago OP.

I'm currently posting from my desktop which is a 25W TDP Kabini APU (4 cores at 2.3Ghz, 8GB of ram), my UPS tells me that it's pulling 40W, and about 10 of that is an nvidia 8500 GPU that I only use so I can watch anime on my trinitron. If I pulled a stick of ram and removed the second drive (old laptop drive) I could probably get it to ~25W.

AMD has also announced a 15W TDP raven ridge APU. So yeah, if you try, you can hit 25W with a little effort, without even going to ARM or anything.

Have you tried undervolting?

You might get some 5W off the reading this way.

Also it would be perfect to run everything including the screen under 25W. That's sort of my vision.

Though with LED screens on 0 brightness show some promise https://electronics.stackexchange.com/questions/30541/lcd-led-panel-power-consumption

Wonder if 13'' screens can deliver good brightness below 10W mark.

>>858022

this too

IOS had been doing this trick by making their UI mostly white due to their panels consuming less on white screen.

It's more efficient to bring in heat with heat pumps than to make it from electricity. With electricity, the heat energy added / electrical energy used = 1. With heat pumps, that ratio can go above 1.

Posting from a 7 year old, 17inch, 35w tdp sandybridge laptop that currently reports between 8 to 10 watts of power consumption, and that's including the screen.

>Have you tried undervolting?

No, because I don't actually care. Also, it's a moot point unless you're getting desktop levels of performance and utility, since < 25W is easily achieved with a raspberry pi or cell phone, if you are willing to sacrifice.

Screens are pretty piggish, but I'm still running a florescent one. Paperwhite displays would be very cool, I'd even tolerate a 5Hz refresh rate on a laptop since I mostly am looking at text

>oy vey dear consumer this new computer uses 0.0000005% less energy, throw off your old non-eco 2 year old piece of crap and go buy a new one now!

>oy vey why did you ask about our manufacturing process

>it's not like most energy is wasted upon manufacture, dear consumer, no way

>why did you ask about those coal plants powering our green electric cars, consumer?

>you ask us why do we employ another generation of useless uneducated chinese youth and dump wastes to Yangtze river when making our "green" li-po batteries and "green" solar cells, right consumer?

Well, it' not like there is no ways of browsing internet in low-power mode. Normies do it all day long, it's called smartphones.

>>858062

that's really good, i get around that on a x230 with default tlp config.

how did you tweak it?

>>858334

I do strongly agree with this. I bought my kabini for its small form factor to replace a core2 era celeron, which is now my fileserver. Electricity has low environmental impact compared to electronics manufacturing. Just like how the greenest car is a used econobox, because gas is better than the cost of manufacturing a new car.

>>857752

You can brose the internet on less than 25W single board computers right now. You wont do it becuase you're a faggot lacking the conviction to put your money where mouth is. Your thread is shit. You are shit.

>>858334

>>858337

Mah niggaz. Planned obsolescence of electronics is a bigger environmental threat than their electricity use.

>If how long before we can browse the Internet

We can't even browse the web on 750W. What makes you think it will ever be possible under 25W? The web is fundamentally broken and there's no solution.

>>858337

They have literally swarms of people tearing and burning old electronics in Africa.

Though advancements in tech should be tracked. What if you have no good deals for used parts. (Unlikely to happen though) The know-how about new stuff might come in handy.

Besides you can unplug yourself more from the system if you combine low power tools with solar panels.

>If not how long before we can browse the Internet for power consumption under 25W outside low spec mobile hardware?

Why the hell would I give a shit? I'll continue using my 300W AMD GPU and I will enjoy it.

Mac mini's idle around 11watts.

>>857740 (OP)

my display alone eats 100w
