[SOLVED-for now] The ultimate package building laptop?

If none of the more specific forums is the right place to ask

Actually, for package building just an integrated Intel GPU is fine, but I guess that's disabled from what I can see on the web page. :( Hey, later this year Intel will be shipping processors with integrated AMD GPUs instead of the Intel ones.


I don't know what the most powerful AMD laptop is, but I think Ryzen support in the kernel is still not fully cooked yet.

That would be most welcome indeed for the required use, +30-40% was (initially?) announced if I remember well.

I think the biggest issue you're gonna have on a laptop is cooling and sadly, there ain't a whole lot you're going to be able to do about it.

i7-8700K...
GTX 1080
Beastly :D
Just flat out "ultimate performance laptop" compiling, gaming, rendering, whatever. Might have to get one to run Gentoo on :P
That looks like a pretty beefy cooling arrangement too, wonder what kind of load it can do continuous?

As for the Nvidia vs AMD debate back a bit, I too have had "fun" with the garbage AMD/ATI drivers. Never again. Nvidia may be non-free and a bit of a PITA, but at least their drivers work.

A review I saw said you're going to roast some delicate bits if you actually try and use it on your lap. I imagine battery life is going to be quite short, too, but that's not a concern for me.

Does anybody here believe in the paradigmatic superiority of open source development?

The amdgpu driver is a massive improvement over fglrx precisely because AMD open-sourced the development and their efforts deserve our support (notwithstanding the firmware issues, which Intel now also have).

Anyway, the idea is that we punish NVIDIA and the other blobby miscreants by denying them our cash and taking the performance hit like a man, righteously.

@stevepusser: sorry for the diversion.

I would go for something like this:

https://www3.lenovo.com/gb/en/laptops/t ... 2TP2TT5800

^ Intel i7-8550U and no nasty NVIDIA cards to be seen :)

OK it's only the mobile version of the CPU but it should still do fairly well.

So we should buy AMD cards and put them on shelf ? :mrgreen:

Thanks! The Lenovo looks nice. You can add a discrete Nvidia card for $125 US :lol:, which would be useful for testing MX's Nvidia installer tool. With that, the i7-8650u, 16 GB RAM, backlist keyboard, and a 512 GB NVME SSD drive, it comes to $2000 and won't roast nuts.

Lenovo has awful support in Europe, don't know about US.

Kinda not what I was suggesting, though :)

I have two Dell Precision laptops; a first-generation and a fourth-generation i7. Both will heat up and throttle back when doing anything that's real processor-intensive (like rendering video or audio). The first-generation machine will trigger thermal protection if you max out *one* core for more than a few seconds; the 4th gen does a little better but will still bump up against thermal protection at 85°C when rendering video. I'm afraid you may lose any advantage that hotrod processor has if the thing throttles back because laptop cooling systems generally suck.

Your use case is processor-intensive; all that processor horsepower isn't gonna do much good if you're using more watts than fan and heat pipes can dissipate :(

Purely out of curiosity, what's stopping you from making a headless (eg, mini itx) build with, say, hostapd for direct access (or, if you're mobile at hotels or something, using the television for a monitor)? Wouldn't the power output and machine weight be comparable anyway? That way, you can also solve the cooling issue, and I don't see the disadvantage to a case like this if your laptop would be massive and heavy anyway.

(I personally just offload any heavy-lifting to a box at home.)

I do, but I also require my hardware to work properly.
This particular hair-shirt is still unacceptably itchy.

Cool. When it works as well as the Nvidia blob, and the actual hardware performs as well as the Nvidia cards (without bullshitting about their power consumption), then I'll use it.
My past experience with AMD/ATI GPUs has been severely lacking in both respects, and Intel doesn't make anything with the performance I want. That leaves one option.

Yeah, I guess all that power can go to waste if you can't run at full speed for more than a short time. I can run my current Acer i5-6200U laptop flat out building kernels for hours at a time and it never gets over 73 C, but I guess the only way to find this kind of stuff is to try and find an actual user review.

I found test results at the notebookcheck site...it seems like most with a "u" processor don't suffer temperature slowdowns. They do multiple runs of the Cinebench benchmark and see if they take longer the more runs they do.

But now I am wondering if it's worth waiting for the next versions of the Intel processors that are supposed to solve any Spectre and Meltdown vunerabilities, and if those will still be subject to the same performance loss with a hardened kernel that the current processors suffer. Those chips are supposed to be out in the next few months.
