<p>Good afternoon</p>
<p>An i7 CPU is very powerful and will have more than enough
capability but it depends on the exact tasks. I carry out all my
mapping with Pentium G CPUs in my computers (i1 equivalent) with
Debian as the OS.<br>
</p>
<p>I would think the amount of RAM you have is probably of more
significance than different models of i7. You can also choose a
distro or desktop environment that is resource efficient,
currently I prefer XFCE compared to some of the other resource
hungry environments.</p>
<p>You could also consider an SSD as being faster than a regular HDD
if disk swapping may occur. <br>
</p>
<p>If your laptop gets too hot it may not be designed for intensive
work and this is probably a factor of the laptop itself not the
workload. It is simply very difficult to fit a cooling solution
within most laptop chassis and a more powerful CPU will need more
cooling. A less powerful CPU may take longer but have less heat
output working at full power for long periods.<br>

<div dir="ltr">Hello,
<div><br>
</div>
<div>I'm thinking of buying a laptop and wondering about the
minimum and recommended specs for a laptop to run QGIS 3.x?
The plan is to use Ubuntu as the OS and the laptop for writing
scripts, working on Process Models, etc... with occasional
full blown tests using 'large' (+500,000 polygon) shapefiles.
My desktop is more than sufficient for this but I'm looking
for something to use when travelling. </div>
<div><br>
</div>
<div>I used to have a somewhat decent laptop but it is older and
gets crazy hot... and does not do well with larger shapefiles.
The old laptop case actually deformed slightly in the hot
areas which screams to me "fire hazard!" and therefore is no
longer used.<span

like to avoid those issues with the new laptop.</span></div>
<div><br>
</div>
<div>The laptops on the market seem to be mainly 7th generation
Intel processors with a wide variation in performance. Just to
keep this simple, let's consider i7 types. There are
designations ending with a "U" which use less power, create
less heat and used in lower performing computers. Then there
are the "H" and "HQ" processors <span
style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">in
higher end computers </span>which sound more capable and use
more power. </div>
<div><br>
</div>
<div>I'm guessing a "U" processor will be overtaxed by the
scenario in the first paragraph. So *if* it does not crash it
will run to the design limit and heat up. If using the "H" or
"HQ" processors it will likely not crash, produce lots of heat
but maybe not too much since it is designed for such intensive
applications? </div>
<div><br>
</div>
<div>Am I understanding the situation correctly? What else might
play a significant role in the heat issue? What about laptops
with built in cooling systems beyond the normal fans and heat
sinks? And most importantly... how to pick a computer /
processor / other items capable of running QGIS with large
datasets? How to find a reasonable middle between performance
and heat? ...and of course not cost too much? Gaming
computers????</div>

<div>Thank you, </div>
