[Qgis-user] RAM and processing speed requirements for QGIS

[Patrick Dunford]

As others have written it will depend on the tasks you are doing.

The performance of any computer can be significantly improved by 
replacing HDDs with SSDs. Modern computers using the NVMe standards for 
SSD (M.2 interface etc) can offer a great deal of speed improvement for 
SSD storage over SATA which is very significant when working on 
intensive projects that use a lot of resources.

The PC platform is significantly easier to expand if resource needs 
change. My seven year old system started out with 8 GB of RAM and 
currently has 32 GB, whilst the swap file performance (virtual memory) 
has been significantly improved with SATA and M.2 SSD storage (now at 
200 GB). The latter provides almost limitless performance capability 
enhancements to the system at modest cost without having to upgrade the 
entire system. I use Ubuntu as the operating system for this computer.
