[Qgis-user] Hardware Recommendations for a High-End PC for QGIS 3.40.14 “Bratislava”

[Zoltan Szecsei]

Hi,
How long is a piece of string?
You might get a more accurate answer to that question 🙂

So, to try to be more useful to you:

  * If Intel, at least i9 "top-end". Look at the number of CPU/threads
    but almost more importantly look at the CPU clock speed as the
    higher CPU counts can lead to slower clock speed. You can play
    around with CPU comparisons on a number of websites. (currently I
    would tend towards AMD, though)
  * Minimum 32GB, preferably 64GB or even 128GB if budget allows.
    Perhaps avoid ECC as it does run (noticeably???) slower.
  * In terms of motherboard design, take 'notice' of the number of PCIe
    lanes available and how fast/what Gen they are.
  * Only use NVMe 'drives', not SATA SSD or 'normal' HDs
  * Graphics cards? I am not sure where the price-break between gaming
    and 'professional' cards is - *maybe someone else on this list can
    help here*.
  * Don't forget to have a "few" decent USB ports - at least 3.2 Gen2 x
    2 (20Gbps) or USB 4 (40Gbps, even 80Gbps) - But remember that if you
    are transferring hundreds of small files (as in multiple File-GDBs)
    the file-system as formatted on the USB will have a major impact
    (downwards) on your transfer speeds.
  * Try to have at least 2.5Gbps network, if 10Gbps not affordable - but
    then to benefit from this you will need to connect to an appropriate
    network.


I run a 2023 Dell Mobile Precision Workstation 7780 with i9-1390HX, 
128GB CAMM non-ECC, RTX-A5000 Ada and a 1TB NVMe for system, plus 
another 3 * 8TB Sabrent PCIe 4 NVMe SSDs.
Overkill perhaps, but one gets used to this too quickly and still 
complains about "this slow piece of rubbish!!!" 😂😂

Not sure if you mean _/stereo/_ 3D visualisation - if yes, you could end 
up spending more on the (Pluraview?) 3D monitor.....

Hope I've helped a bit, at least.

Regards and have fun,
Zoltan
