If I were to guess it's likely still 12 lanes to cut down on die space (aka technically 20x on die, but 8x are reserved by the iGPU like normal), but they're now PCIe 4.0 meaning effectively double the bandwidth. This should make adding stuff like uses up PCIe connections like fast networking MUCH easier than it was with the somewhat I/O deficient Raven Ridge & Picassso platforms (where stuff like 1x lane WiFi chipsets were annoyingly common to save on lanes). Well, assuming more & more such expansion devices start to come around with native PCIe 4.0 support that is.
You are right. Damn that's big miss. Designing laptops with just 12x available 3.0 lanes was already super tight with Raven Ridge/Picasso. And that's before you start talking about new tech like WiFi 6 for ex.
A single PCIe 3.0lane still provides 1GB/s bi-directional. 500MB/s read/write should more than suffice for even the most recent WiFi chips. It's still a big limitation for potential Thunderbolt implementations, though, but I'm part of the "couldn't care less" market on that front - USB C does everything I need at a much lower cost.
One advantage of the mobile parts bringing up the rear is that previous Ryzen mobile parts have included features that weren’t ready when the desktop parts came out.
Hopefully, AMD is willing to talk about how these into parts compare to other members of the family. For example, one CCX or two?
maybe now, there will be some fully premium AMD laptops. Ryzen 3000 laptops were better, but still not there.

Thanks for the details Ian. I can't wait for reviews!It seems Intel has run out of time with their 14nm games.

Do we know the PCIe lane count? Is it still 12 lanes or does it get increased this gen?Also, are there any design wins with TB3 or USB4?

NOT PCIE 4.Still 3.0 which is plenty.
4 would use to much power.

Wifi 6 doesn't exist nor would it use more lanes, lol.Spunjji - Wednesday, January 8, 2020 - link

Not sure, but i think it is pcie 4 internally, but the accessible ~chipset lanes are pcie 3.The Hardcard - Monday, January 6, 2020 - link
