Looking Ahead To AMD Ryzen Mobile On Linux

But this is just insurance against patent lawsuits. It wouldn't mean AMD would be willing to give up one of their advantages...

Got it, thanks.

Nope, battery is just plain garbage. I think it was 4200mAh. I knew it was bad when I bought the laptop but it was replaceable so I wasn't too concerned about it. However, what I didn't know until later is the best battery I can get will maybe get me 4 hours. Such a battery costs around $100 and is pretty bulky, so I'm like "screw that".

Oh, well, that makes sense.

I don't recall what it came with. The stock wifi worked but was weirdly slow and would randomly disconnect once in a while. So I bought some cheap M.2 adapter known for good Linux support and haven't had issues since. To my knowledge, the stock wifi works perfectly fine in Windows, so when given the opportunity I'll use it for someone else's PC.

Yea, that sounds like Realtek. I'm guessing that's the default choice. However, I also read that they have a wifi whitelist, cards that are not in it cause the UEFI to fail to boot. They do have an Intel and an Atheros card in a whitelist, andt hey are not expensive, so indeed replacing it is not that difficult, but still I'd rather have everything work right without having to break open the thing...

Huh, that is pretty weird. Well, the speakers are a given. For the battery, maybe not all power management code is there yet, or something? The USB issue is the only one that would be a problem in my case, though. But yea, maybe you just got unlucky with a bad model or something...

Out of curiosity, what wifi card did you get? Their driver page ships drivers for 3 manufacturers, so it seems to be a lottery which one you get more than anything else.

Anyway I'm not saying to avoid Lenovo; I'd still prefer them over Toshiba, Acer, and some Dells. But, they are slipping in quality lately, so be wary of what you get. The laptop I got had almost no reviews (professional or store reviews) so it was kind of a gamble. Apparently I lost on that one. The performance and wattage of it is otherwise perfectly fine. The main reason I haven't replaced it is because nothing new will improve my overall daily user experience (other than, for example, having a keyboard that doesn't feel mushy or something less heavy).

A lot was wrong with it. It was so bad that if I were a Windows user, I'd have returned it after 2 hours of use, but thankfully installing Linux on it fixed many (but certainly not all) of the out-of-box issues with it. Currently my greatest gripes about it (that I didn't fix) are the tinny speakers, ~2h battery life, and the USB 3.0 ports cause stability issues if the device I plug into them draws roughly 1A.

The weird thing is I've seen cheaper newer Lenovos that were built much better, so I don't know why my model was so especially terrible.

With the Zen architecture though, AMD has shown it can get great performance, while not remaining power hungry in comparison to Intel's offerings. Just look at the 6900k compared to the 1800X at launch. Even Intel's latest i9's seem more power hungry than Threadripper. This shows, AMD now has a efficient platform. It sounds like they have done all things right and in bringing this to mobile, will have a well performing CPU that is just as efficient as Intel in the mobile space, while offering a potentially better package with Vega graphics over Intel.

You have a very valid point, however, it is important to consider that not all architectures scale well. For example, in Intel's efforts to compete with ARM, the only way to keep up with the overall wattage was to cripple the performance to the point that ARM ended up being as fast or faster. x86 is just too complex to scale down to levels that are useful for phones or microcontrollers, unless you start stripping away instruction sets (at which point, might as well just go for ARM). Meanwhile, the inverse can also be said: try getting an ARM CPU to compete with an i3 and it will become much less efficient at doing so.

Zen's design strongly suggests it is meant to be modular and expandable. Its performance and value seems to have only got better as you scale up, so, I'm a bit wary how it will perform in a laptop environment where it is relatively crippled compared to desktop and server counterparts.

Hm? What's wrong with it? The 720s looks pretty nice to me (I don't care much about memory latency, no gaming), as do the 320s and 120s. I was just thinking about purchasing a laptop, and an AMD-based one would be pretty nice, especially considering that it has USB Type-C and DDR4 memory.

Didn't Intel plan to start using AMD for their integrated GPUs? Or that was a false rumor?

Somewhat false rumour.
The thing is: Intel 'needs' to pay 'someone' for GPU technology so they can integrate GPU without being sued for patents...
And it seems that the contract with nvidia is/was coming to an end, so it'd make sense Intel would try to get a new contract. If you have into account that Intel and nvidia's relation has seen better days and that AMD already has a few cross licensing deals with Intel, it woudlnt be surprising for Intel to make a similar deal with AMD as the one they have/had with nvidia...

I've always liked the Intel NUC form factor. It's basically a very small, very quiet desktop that's reasonably priced... but had laptop parts inside it. Please someone build similar, but with the new AMD mobile chip. At a M.2 (or 2), 2 SO dimm slots, GigE, and wifi.

Probably the best thing about these APUs is that there won't be any attempt to use some kind of optimus, PRIME or other kind of hybrid graphics solution. For me that'd be a big plus. So many laptops have nV graphics and I refuse to install the proprietary bundle, and nouveau is held back by nV themselves. It is just a shame that Intel graphics has been rock solid compared to AMD. But once again, that's only useful if there are no discrete graphics bundled with it.

Razer is one of those companies that people like to talk trash about due to the glitz and price tags that they use, but I have yet to know an actual Razer user who was unhappy with their purchase (except sometimes mice)

I bought a mechanical keyboard from them, and the enter key became unreliable pretty quickly. So add me for that.
