I'm not familiar with laptops for chess, so what's the current best solution? Or should one wait and buy a laptop with a strong graphics card for lczero in a few months?

> laptops for chess


I always shudder when I hear that phrase.

Workstation laptops will have the best cooling, but they often stick older Quadros in which you definitely don't want for Lc0

well, same for me, but the problem is that it needs to work at tournaments with no internet connection...

In that case I'd go for a Dell Precision. But you'll probably get better value for money from a more local brand near where you live. Dell's after sales support is very good if you get a component failure (not out of the question when you combine "laptops" with "chess")

Probably high end gaming laptop at this point, the cpu will be as fast as they can fit into a laptop and whatever high end graphics card they put in there should be as good as can be expected for any of those AI based engines in the future. It *might* be the case that there is some workstation laptop with a xeon in it that would be faster but it couldn't be that much faster and definitely wouldn't have much of a graphics card, and also the price would be insane.

I suppose you could also just build a serious rig at home, get a cheap laptop and telnet or remote desktop into your home rig for analysis : p

any idea which manufacturers provide a good cooling? Maybe a solid laptop performing at a good speed is preferable over a high-end cpu overheating after a few minutes.

Hi Felix, What you can do is run an external GPU on a laptop ... I guess in theory you could rig up a https://www.overclockers.co.uk/pny-nvidia-tesla-p100-gpu-accelerator-16gb-hbm2-3584-cuda-core-gx-052-pn.html

Do a google search for something like `external GPU on laptop` https://bit.ly/2THuXd3 and you will find plenty of links plus videos, I think Linus did one last year

I cannot think otherwise how you would cool anything decent in a laptop, I have seems attempts at watercooling GPUs in laptops.

Tony

aha, that's interesting. For me it is difficult to judge in what period of time lczero will probably outperform stockfish (both running on a laptop).

Hi Felix, As you already know whatever latest generation CPU with its many cores you have in a laptop it will have cooling issues and start to throttle very quickly and do not perform better than say an i7 ... There is of course the option of water cooling a laptop https://www.youtube.com/watch?v=MWg0ZoJcD0A there is also lots of links there ... So maybe a water cooled Laptop and an external GPU .. Also depends how much money you want to throw at it .... Not to sure ATM how portable the setup would be dragging an external GPU and its fittings everywhere

Tony

I can just picture pulling that "thing" out in a café ...Student Union where Felix lives. That would be novel! :yell:

Privacy out the window! Where the hell do you plug that monster in?

$6000 for laptop computer chess! That's dedication! PLUS!

addendum:
OH GOD IT THROTTLES UNDER LOAD! :eek:  Computer chess should achieve that ditty!

Now! This is what I've found to work. If you download RealTemp and go into setup check "Disable Turbo" you are good to go!

Hi Tony,
I've also been researching for a laptop but not using the same criteria.
First off -you have to STOP looking for a laptop that will be equal to a desktop computing system-
Gaming laptops are fine for certain computer gaming, but full on computer chess analysis raises temps fast! It doesn't take long before you have a shutdown. Just get a decent processor with enough ram and SSD storage. You don't need top of the line graphics for computer chess. You have to remember that most users aren't into computer chess. Games focus on Graphics, ram, and processor to handle the bundle. Chess is heavy on computation.

You can get away with just a decent processor, ram and storage - speed of analysis -you may get 14,000 kN/s on a 6 core , decent laptop -for a short period of time before the heat temps catch up with you.

Addendum:
6 core i7-8750h

The really powerful GPU cards cannot be put into a laptop, because they consume over 250 watts.
Your pants would catch on fire.

my GTX 1060 uses under 120W of power

Hi Felix!

How are you doing? Long time ago since I spoke with you :-).

I never use a laptop for chess engines. Good old PC is still the best for me!

Kind regards, Jeroen

From my experience your biggest headache will be the cooling fan. Most are not ball bearing.  You buy a high end gaming laptop that has a cheap cooling fan that ends up in RMA within a short period of time when you use it for Chess purposes. Other gaming doesn't stress the laptop system as does computer chess.

Now, I ended up sending my laptop that was a gaming system -bought some 5 years ago to RMA after the fan burned out. It didn't take long for the replacement fan to end up repeating the high whining attempt to cool and final  burn out .

I ripped out the bottom of the laptop pulled the failed fan- connected wires here and there and... attached a 12 inch (YES!) house fan! Up side down to the bottom of that laptop -Styrofoam in each corner to give it some lift - When it booted tapped enter to bypass blab blab no cpu fan crap and entered into windows-

Got the best cooling on that gaming lap top ever! Made Tony's table Desktop look elegant!
(had to duct tape the battery into place, and SSD drive!) :)

Addendum:

You have to disable Turbo!

absolutely and 100% agree! I had to take my sons Asus Rog gaming laptop apart ...it reached 92-96C in gaming (hacked vBios and overclocked GPU, otherwise with the stock vbios and settings it throttled way to much), and with chess engine around 99-100C! I had to re-paste the CPU and GPU heatsinks ...well the result...a bit better, around 88-98 area ...but not the real thing....after all I drilled a bunch of holes on the bottom of the case -this laptops actually suck in air through some tiny holes under the keyboard- plus I bought and attached an external laptop cooler to have decent temps (under 70C) and avoid throttling.

Hi there,

If one needs a really high-end (and future proof as well) chess laptop, then maybe the so called "well established" notebook brands market are'n quite the best place to look around. And if the laptop might be used for leela zero too..then a really powerful (or two!) -and why not upgradable- GPU setup is needed.  I recommend to take a look at the laptops from Eurocom. Many does not even heard about the company, but they are really in the deep waters of making brutally powerful laptops. They too build SLI (dual) Geforce GTX 1080 models: https://www.youtube.com/watch?v=k56ZBYx4VEY.

And what is even best is that You can customize the model of your choice http://www.eurocom.com/ec/configure(2,385,0)SkyX9E2

Of course, this machines are not cheap, they consume more power (less than a similar desktop) but they can even outperform many dedicated and powerful desktops...
