It doesn't seem like it supports LPDDR4, so I don't think they are competitive for the "macbook pro" market.
AMD takes on Intel with new Ryzen processors for laptops

Re: AMD takes on Intel with new Ryzen processors for laptops
#62Desktop Ryzen still suffers with thermal/power efficiency issues compared to desktop Intel cores, so I wonder if they've managed to address that issue for these mobile cores. If not, I wonder how customers will feel about paying a battery life tax for better performance... Incidentally, AMD GPUs have been at a disadvantage compared to NVIDIA's in the power management area for a while, as well. Which is unfortunate be…
Ryzen 3 1200, 4 core 3.1/3.4Ghz vs. i5-7400 3.0/3.5Ghz the Ryzen uses .12 watts more at idle and 2.19 watts more at all cores full load.
That is a pretty small (<5%) gap.

#63Unfortunately anyone who takes their security or privacy seriously will be totally unable to use this. Every AMD chip contains a likely backdoored system called AMD Secure Processor (formerly “Platform Security Processor” or “PSP”) [1]. This separate processor contains closed source, proprietary binaries that have complete and unrestricted access to the host. Despite a large petition for AMD to opensource this, they…
Does this exist on Epyc platforms that don't use a traditional chipset?
This is bad, but seems like more of an incremental issue than anything. Can you audit every line of source in your system? No closed source drivers or firmware on any devices? No devices on your network with vendor controlled firmware? You log all network I/O through a passive tap? For the average user targeted by a state actor this makes little difference.

#64Dear Lenovo: we would like this chip with a seven row keyboard very, very much. A485 perhaps?
Let's wait for the 30th Anniversary Edition. Then it would be the perfect time anyways for me to get a new laptop.

Yep, AMD lacks the "courage" to limit customers to 16 GB of RAM.

#66How are the Linux Radeon drivers these days. Last time I tried (8 years ago) they were awful compared to the NVidia equivalent. But now that I might be able to get a 3 pound ultrabook with decent graphics, I'm willing to put up with a lot more inconvenience .
The open source native kernel drivers (AMDGPU) are excellent, the only minor but incredibly irritating issue is the lack of proper fan control, i.e. the GPU fan never turns off like it does on Windows. Thats why I again moved off AMD to nVidia (i like silence)

The PSP is part of the processor die so it is included in Epyc.

Dear Lenovo, please make A485 based on the (future) 45W Raven Ridge, not the currently released ones.

#69Earlier quoted context omitted.
This is an acknowledged and solved fab issue. Get it RMA'd.
It is not a solved issue at all. Chips are still coming off the line with the issue, the only solid fix is getting an RMA'd processor (AMD are hand-checking these units for the issue). The assertion of there being a "safe date range" (ostensibly, date codes >= 1730, i.e. chips manufactured during/after Week 30 2017) was made by the Phoronix Forums webmaster on the basis that he hadn't seen any user posts reporting pr…
Didn't know that. Since they know how to fix it on TR/Epyc, why would they release a brand new line with the same issue?

Do the fans show up under lmsensors?

If so, then you should be able to control them manually.
