Wow. They're really serious about Lakefield. I'm genuinely interested in seeing where people use this product, and when it will be available.

So I am assumming that is a usb-c port to the right. That is 60 pixels tall and the board is 900 pixels wide (so 15x the width of a usb-c port.) Wikipedia says usb-c is 8.25 mm wide and thus we are talking a board that is roughly 12 to 13 cm wide, roughly 5 inches wide for the motherboard.

Based on the 8.25mm unit of measurement the board measures 13.2cm in length and 3.2cm in width. (16x and 3.84x respectively)

If it is for a smartphone then it is likely to be a micro-USB port. Whether that changes the dimensions I do not know.

Hmm. According to AT's coverage of Intel's CES keynote, it looks like Lakefield should be available at about the same time as IceLake U/Y, albeit only in whichever OEM devices will be using it. It would be kind of cool to see this product enter the SBC space . . .

It's not for a smartphone, at least not for a normal sized one. It is close enough in length to look as it may fit, but the actual area of the board is way bigger than board area in modern smartphones. To give a quick example so that we can establish a reference point, board area in my previously owned Nexus phones was around 24cm², and this board is around 40cm² while lacking dedicated space for sensors.

Here's the board projected alongside logic boards from iPhone 8 Plus and Google Pixel 3 XL, some of the bigger phones around. The iPhone example should speak more than numbers and words.

Nods I did not do exact projected size in cm or inches for 8.25 is the size of the internal usb-c but remember we are looking at an outside usb-c port on the right and I have no clue how much extra space in fractions of a mm or a mm is done to provide that tight socket that makes a usb-c work as a coupling (female and male pipes and all that jazz.)

Aka we are talking phone size of motherboard where no phone maker wants that size of motherboard but technically it can be done. For example the galaxy note 9 phone size (of the phone not the motherboard) is 161.9 x 76.4 x 8.8 mm. Well the thing on the right is the galaxy 9 motherboard.

Aka you can make a phone size device with this size of motherboard, it will not be a good phone for there will be all these compromises (for you need additional hardware like modem, dsp, the ssd which plugs into the m2 port will take more space, blah, blah, blah) but we are easily talking something that will work with a nexus 7 or smaller device can handle this size of motherboard. (Do we know the thermal situation and so on yet?)

Receptacle opening: ~8.4 mm x ~2.6 mm


So the board is slightly bigger at around 134-135mm.

As I already point out in my previous post, being the size of a big smarphone does not make it suitable for a smartphone. Phone boards are almost half the size.

Isn't the Surface Phone supposed to be dual screen? Maybe put the logic board behind one and the battery in the other?

Wouldn't it be easier to just make a proper custom smartphone board for Lakefield and not insist on using this "pilot" board which is obviously meant to be the building block of a very small PC?

Look at other modern smartphone layouts: the USB-C isn't even on the board, and most if not all have very weird shaped cutouts meant to reach areas around the battery.

And one more example, look at the board bellow:


It's size, measured based on the tech specs of a chip on the board, is roughly 112mm x 37mm (excluding the lower protrusion).

This board too, should someone insist, could theoretically fit into a big smartphone. And yet it was made for the 12" Retina MacBook 2017.

3 things.

1) First I look at your notes and measurements and all I can think is COOL. (My facial expressions are like Gregorry House from House MD when he says cool.)
2) Thank you or your work.

As I already point out in my previous post, being the size of a big smarphone does not make it suitable for a smartphone. Phone boards are almost half the size.
3) Yes you sad the things artfully before, I am merely agreeing with you, even if my agreement is not as artful, not as concise, etc, etc. I am repeating #3 for I think this is such an important point.

It would go nicely into a tablet though.
Exactly. This board is substantially smaller than the 11" 2018 iPad Pro motherboard. In fact I bet there is engineering pressure to make the board "bigger" for such a larger tablet so the board is roughly the size of the length of the table, making such a board that size makes sense for structural reasons.

Why I bring up the last sentence? I bet this board will make an awesome 7" or 8" device, or a courier type device with two screens.

The problem now is not the motherboard or soc / cpu tech but instead getting the screens right. The problem of making a good 7" or 8" intel tablet with good performance (core level performance, not atom of yester year performance) is not whether it is technically possible it is instead whether there is a big enough market to make such a device in the first place.

Actually, if it weren't for your initial observation we wouldn't be here, as it took me the entire process of looking at phone boards in my house (got a few in storage) and then making comparative measurements based on modern devices to understand the problem.

My initial reaction was completely different than my conclusion.
