That looks like a smartphone logic board
A smartphone with an M.2 connector? Nah.That looks like a smartphone logic board![]()
I was more talking about the general size and shapeA smartphone with an M.2 connector? Nah.
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)So I am assumming that is a usb-c port to the right.

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.So I am assumming that is a usb-c port to the right.

Almost all new phones use USB-C.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.
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.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.
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.)Based on the 8.25mm unit of measurement the board measures 13.2cm in length and 3.2cm in width.

Receptacle opening: ~8.4 mm x ~2.6 mm
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.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.
Isn't the Surface Phone supposed to be dual screen? Maybe put the logic board behind one and the battery in the other?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.
It would go nicely into a tablet though.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.
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?Isn't the Surface Phone supposed to be dual screen?

3 things.https://www.anandtech.com/show/8377/usb-typec-connector-specifications-finalized
So the board is slightly bigger at around 134-135mm.
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.As I already point out in my previous post, being the size of a big smarphone does not make it suitable for a smartphone.

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.It would go nicely into a tablet though.
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.3 things.
It probably is Microsoft's Surface Andromeda and Centaurus. Both might have been shown in the Lakefield trailer.So it probably is the dual screen tablet/phablet.
You could port the *Chipset* to TSMC, not the Modem, not at this stage of the development cycle. Porting a Modem to a different Fab or Node is about as much work as porting an CPU, if not harder for 5G.Ding ding ding! Winnar. But we don't know if it has anything to do with yields. Tiny little modems? No. Lakefield? Yes. Wait, what? If anything the modem should have been easier to fab on 10nm than Lakefield if yields are still in question.
The decision to move the 5G modem to TSMC would have to have been made a long time ago, yes.You could port the *Chipset* to TSMC, not the Modem, not at this stage of the development cycle. Porting a Modem to a different Fab or Node is about as much work as porting an CPU, if not harder for 5G.
So you are suggesting, after 4 years of getting their Modem to their own 14nm Fab with XMM 7560 in the iPhoneXS, and likely the 7660 in 2019, they have decided to move 8160 back to TSMC, and the decision was made before they even had their first 14nm Modem Shipped.The decision to move the 5G modem to TSMC would have to have been made a long time ago, yes.
Well they are obviously not going to be able to deliver enough modems for use in the 2020 iPhone if it's on Intel's 10 nm. And once they lose the contact they are never getting it back.So you are suggesting, after 4 years of getting their Modem to their own 14nm Fab with XMM 7560 in the iPhoneXS, and likely the 7660 in 2019, they have decided to move 8160 back to TSMC, and the decision was made before they even had their first 14nm Modem Shipped.
And you know that how?Well they are obviously not going to be able to deliver enough modems for use in the 2020 iPhone if it's on Intel's 10 nm. And once they lose the contact they are never getting it back.
