<div dir="ltr">Slightly off topic, but I recently investigated low-cost laptops. We wanted to compare between a LattePanda (atom x5-8350) and a raspberry pi 3 (<span style="color:rgb(73,73,73);font-family:DDG_ProximaNova,DDG_ProximaNova_UI_0,DDG_ProximaNova_UI_1,DDG_ProximaNova_UI_2,DDG_ProximaNova_UI_3,DDG_ProximaNova_UI_4,DDG_ProximaNova_UI_5,DDG_ProximaNova_UI_6,"Proxima Nova","Helvetica Neue",Helvetica,"Segoe UI","Nimbus Sans L","Liberation Sans","Open Sans",FreeSans,Arial,sans-serif;font-size:13.2134px;background-color:rgb(247,247,247)">BCM2837)</span> for computer vision processing. The cheapest way to get hold of the x5 processor quickly was in a chromebook on from a local store for about 200NZD (I am currently located in Switzerland, and it cost 150CHF). <div><br></div><div>What we found was that the atom X5 processor completely dominated the <span style="color:rgb(73,73,73);font-family:DDG_ProximaNova,DDG_ProximaNova_UI_0,DDG_ProximaNova_UI_1,DDG_ProximaNova_UI_2,DDG_ProximaNova_UI_3,DDG_ProximaNova_UI_4,DDG_ProximaNova_UI_5,DDG_ProximaNova_UI_6,"Proxima Nova","Helvetica Neue",Helvetica,"Segoe UI","Nimbus Sans L","Liberation Sans","Open Sans",FreeSans,Arial,sans-serif;font-size:13.2134px;background-color:rgb(247,247,247)">BCM2837</span> in everything except cost.</div><div>- In processing power, the intel atom was several times faster than the Pi3 on the computer-vision benchmarks we ran despite them both having similar clock speeds and core-counts.</div><div>- The atom is a normal x86/64 processor, so you can run normal distributions and software on it. The only issues are an unsupported sound-card [and a hardware fault on the lid-closed switch].</div><div>- To our surprise, the intel processor has about the same power consumption. The Pi3 requests a 5v supply of 2.5A, the latte panda requests a 5v supply of 2A, and the laptops supply is 5V 3A. So at the very least, the consumption is comparable. In practice, the chromebook's battery drains incredibly slowly - much slower than any other system I've used. It even outperforms the battery life of my smartphone for web-browsing.</div><div><br></div><div>In the end we didn't end up doing computer vision to solve the problem, so we used neither the lattepanda or the Pi. The laptop is now running as a self-hosted gitlab server, which it does admirably at. Unlike when I tried hosting services on a Pi, the services are up to date and run much faster. The biggest limitation for me is that there's only 2Gb of ram and gitlab idles using 1.5Gb of it.</div><div><br></div><div>So if you need a lot of processing power and you can deal with a 90USD SBC instead of a 35USD one, and you don't need GPIO's (or are happy to have a co-processor), then the low end of X86 processors may be better than the high end of ARM processors.</div><div><br></div><div>Geoff</div></div><br><div class="gmail_quote"><div dir="ltr">On Sat, Dec 1, 2018 at 7:37 AM Andrew Errington <<a href="mailto:erringtona@gmail.com">erringtona@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto">At this month's meeting (it being December already) I plan to bring the fabled $100 laptop which was recently delivered:<div dir="auto"><br></div><div dir="auto"><a href="https://www.pine64.org/?page_id=3707" rel="noreferrer" target="_blank">https://www.pine64.org/?page_id=3707</a><br></div><div dir="auto"><br></div><div dir="auto">You can read a decent review here, together with a description of the byzantine ordering process:</div><div dir="auto"><br></div><div dir="auto"><a href="https://hackaday.com/2017/04/28/hands-on-with-the-pinebook/" target="_blank">https://hackaday.com/2017/04/28/hands-on-with-the-pinebook/</a><br></div><div dir="auto"><br></div><div dir="auto">Yes, I did all that, and the US$100 laptop turns into a NZ$200 laptop when you add shipping and currency conversion.
