Check whether your chip is affected by the segfault bug. It affects Ryzen CPUs, but not Threadrippers or Epycs. It's a free RMA: https://www.reddit.com/r/Amd/comments/6ubmd1/ryzen_compilati... If your system is totally new, try checking your RAM with memtest too. My Threadripper build had similar issues in Linux and Windows. Ended up being my PSU. I tried to save $30 buying a refurb one from Corsair. My system would…

> On a desktop you can always swap hardware, but on a laptop you're stuck with what you get. Raven Ridge is the same stepping as Ryzen, i.e. potentially subject to the segfault bug. I'm really curious whether it will manifest there too or not. It's a pretty generic errata that manifests under load. Compiling happens to be one way that flushes it out pretty reliably (as with many errata), and nerds do a lot of compili…

Laptop RMAs are way more expensive since they have to swap the entire board w/CPU or reflow solder on a new chip. Can't imagine any OEM will willingly take that hit. Since these issues are well known, I'd bet AMD has to fix them; OEMs will mandate it as part of QA. Either that or they'll force AMD to eat the costs like Apple did with NVidia.

Finally laptops gets freed from 2 anemic cores. Intel will now 'suddenly be in a position' to rush reasonably priced 4 cores to the laptop market.

AMD needs to be competitive for the health of the industry and consumers. There is little doubt now Intel was holding the market back.

We have seen similar stagnation on desktops with any slight step magnified by the tech press desperate for content. And fortunately AMD have an efficient architecture with Ryzen.

Dear 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.

I'd love to have the 7 row on laptops which are not that special. I did buy the T25, mind you.

This is a known issue that only affects early revisions of Ryzen CPUs under specific workloads, so it's unlikely to appear in new ones like the mobile Ryzen. If you're affected, AMD will RMA your chip for free. And AMD isn't the only manufacturer to have such issues. Intel had a bug in Skylake where it would crash under heavy load with Hyperthreading enabled. Modern CPUs are complicated beasts.

How do you RMA the CPU in a laptop though, I would expect it to be soldered in?

I guess through the manufacturer who gets to rework the main board ... gah how annoying that must be. I can easily imagine such a process taking weeks.

I hope you're right. :)

Desktop 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.

5% is a lot these days, and that Intel CPU will beat Ryzen clock-for-clock as well. Laptop manufacturers are fighting over every percentage point of gains these days, not trying to move backwards. People want to see all day battery life with reasonably good performance.

I like AMD and want more competition for Intel. If you have a use that scales across many cores, AMD is a great value for workstations. Their new server lineup is pretty compelling too. But if they want to win in mobile they need to be better on power and thermals even for normal users who won't use the iGPU's capabilities heavily.

How 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 AMD drivers have gotten a complete overhaul. The open source drivers are amazing. The Nvidia drivers suck in comparison. Have you seen the post from the Sway developer that was basically "fuck you Nvidia"?

Linux AMD open source drivers are top notch now. Even have really good foss OpenCL support. The only asterisk right now is that you only want to use these new APUs / any Vega GPU on distros running kernel 4.15 or later (which will release probably Jan of next year).

How are the open source drivers for games? Can you render Civ 5/6 or Rocket League?

Heck, I've been playing Mankind Divided on a 580 using open source drivers. Rocket league should be fine even with the smaller integrated GPU.

AMD's game is never about "winning" - that is not even considered as a possibility. Surviving and getting 10-20% marketshare is a home run for them.
